DDT news: Ethio Sun reports, “Ethiopia and Botswana in banned DDT pesticide deal”

January 12, 2012

How many hoax claims of Steven Milloy, Roger Bate and other DDT advocates are exposed in this one news story?

Somebody count.  The story reveals

  1. African nations still use DDT.
  2. There’s a lot of DDT in Africa to be used.
  3. Some nations don’t use DDT due to fear of health effects on people; they appear to have weighed the alternatives, and found better ways to fight malaria without DDT.
  4. DDT is cheap in Africa (US$4.50/kilogram).
  5. Despite the U.S. ban on DDT use on U.S. crops, some nations in Africa kept using DDT (the article misstates the case for a worldwide ban — there has never been a worldwide ban).
  6. DDT use is not assumed in Africa to be a great way to fight malaria.

I don’t mean to suggest EthioSun as a sterling source of information; but it’s not difficult to find stories like this with frequency, out of Africa.  Each of them refutes the case for more DDT, so that there really is no good case to be made for more DDT, anywhere.

Ethiopia and Botswana in banned DDT pesticide deal

Posted By On Thursday, January 12, 2012 06:32 AM.

Ethiopia is set to export about 15 tonnes of the banned pesticide, DDT, to Botswana, it has been revealed.

This follows a recent suspension on the use of the pesticide by the Horn of Africa nation, which cited adverse effects of human health and the environment as reasons for the decision.

Adami Tulu Pesticide, a state owned company has huge stocks of DDT, which it will reportedly sell to Botswana at US$4.50 per kilogramme.

It is estimated the company has 450 tonnes of DDT in stock.

The US led a worldwide ban on the use of DDT as a pesticide in 1972 following reports of adverse side effects on humans.

However, Ethiopia along with a few other countries continued the use of DDT in the fight against malaria.

Activists have demanded that the ban be lifted, in order to allow the use DDT in the elimination of malaria, especially in developing countries.

More than half of the estimated 80 million people in Ethiopia are said to be at risk of contracting malaria.

According to the World Health Organisation some countries still use DDT to fight malaria.

The disease killed over half a million people worldwide last year, most of them in Africa.

There was no immediate confirmation from Botswana about the planned export.

Steve Milloy, Roger Bate, Richard Tren, Henry I. Miller and others hoax us when they say DDT can save mankind, or even help save mankind.  See also Tim Lambert’s takedown of Goklany’s post.


More misunderstanding of the case against DDT

December 21, 2011

Well-meaning but misinformed dog breeder Terrierman (a guy who goes by the handle PBurns, too)  is just the latest to fall victim to false and nearly false claims about DDT and its effects on birds.

One of the claims made by pro-DDT and anti-environmental protection, anti-science groups is that DDT is not the bad guy in bird deaths.  The late DDT-nut Gordon Edwards said DDT had nothing to do with eagle deaths, and pointed to the 300-year decline in eagle populations from the time European settlers began shooting at them.  This idea has been touted by the chief junk science purveyor, Steven Milloy, and by many others over the years.

So, in one of his several posts slamming eagle conservation efforts that include stopping the use of DDT, Terrierman said:

What’s the story? Simple: that Bald Eagles and Osprey were pushed to the edge of extinction by DDT.

Not True.

Actually, that is true.  Terrierman got it wrong.  DDT was, indeed, threatening the very existence of the bald eagle.  While it is true that there were other pressures, some long-standing, it is also true that once those problems were cleared, DDT still barred the recovery of the eagle, plus other species like osprey, peregrine falcons, and brown pelicans.

What is the story?  The story is that eagles have been under assault since Europeans found America.  By 1900, eagle populations across North America were dramatically and drastically reduced.  A federal law in 1918 made it illegal to shoot eagles, but it had little effect.  A tougher law passed in 1940 finally got some traction.

But eagle recovery didn’t take off.  In the late 1940s and early 1950s bird watchers, and bird counters like those volunteers who contribute to the annual Audubon Christmas Bird Count, noticed that young eagles disappeared.  Simply, adult, breeding eagles were not able to produce young who survived to migrate, mature, and breed later.

The culprit was DDT.  DDT kills young eagles in three ways, known in the 1960s.  It poisons them so they cannot grow in the egg.  It poisons them so they die after a period of growth.  It poisons them so they are unable to eat and digest properly, so they die shortly after they hatch.

DDT can also screw up the sexual organs of young birds, so they are unable to breed — perhaps a fourth way DDT kills young, by simply preventing their creation.

Then, in the 1970s, we found another way DDT kills species:  DDT makes the eagle hens unable to form competent eggshells.  The young die because the eggs cannot survive incubation.

DDT also kills adult eagles, especially migrating birds.  DDT accumulates in fat tissues, those fats that migrating birds burn.  When the birds migrate, the DDT comes out, and it can literally stop the heart or brain of the bird in flight.  (It kills bats the same way.)  Birds lost in migration rarely get found for necropsy.   The bird count simply falls, the population sinks one individual closer to extinction.

Does the dog breeder know all of this?  I can’t tell — I tried to correct his errors at his blog site, but after I provided a link to an article that showed DDT appears to be harming California condors as well — in a post he has censored in moderation and which will never see the light of day at Terrierman, I predict — it’s clear he’s not up to gentle correction.

One more blog from which I am banned from telling the facts.

PBurns, if you’re bold enough to comment here, your comments won’t be censored (so long as not profane).  We need robust discussion, and I encourage it.

Below the fold — my final post to Terrierman, which he won’t allow through moderation.

Annals of DDT: No DDT produces benefits in Thunder Bay, Ontario

December 4, 2011

My news grabbers frequently take in articles about the recovery of some wild species in some far-flung place, a benefit of our having stopped the use of DDT in the area.

It occurs to me these stories should be filed away somewhere for future reference.

For example, here’s a letter to the editor of The Chronicle-Journal, in Thunder Bay, Ontario:

Let’s not reverse gains in falcon population

Saturday, December 3, 2011

I grew up in this town in the 1960s and ’70s never having seen nor heard a bald eagle or Peregrine falcon. I could only listen as my father (an MNR game warden) treated me to stories of the magnificent raptors previously living along the Nipigon River, Sibley and the Nor’Westers. I was 25 years old before I saw my first bald eagle and that was in Minnesota.

Decades of DDT use decimated the predator bird population to almost extinction in Ontario. The government eventually recognized the problem and corrected it by banning DDT in 1970. With the help of local groups, finally the birds are back.

In 1989, the Thunder Bay Field Naturalists, with support from the Ministry of Natural Resources, launched Project Peregrine “in an attempt to reintroduce this species to the Superior north shore . . . In 1993, successful nesting peregrines were recorded for the first time in the last quarter-century . . . due to an abundance of excellent habitat.”

A mere 20 years has gone by. Are we going to allow another crime against these species?

Allowing Horizon Wind to rape the escarpment for a few megawatts that we do not need now or in any foreseeable future is falling into a bully trap.
Parties have stated there will be no harm to the birds or to the escarpment. Au contraire. The blasting alone, not to mention the construction and roads, can be compared to demolishing the whole north core downtown and building a skyscraper no one intends to occupy.

Leave the birds and the escarpment alone. Go home, Horizon Wind.

Art historians do better than conservatives on the history of DDT

November 11, 2011

The art historians at least get the facts right — why can’t conservatives and erstwhile scientists like Steven Milloy get it right?  This is from “The War Against Bugs,” by Steven Heller at imprint:

The War Against Bugs, by Print Magazine -- a Neocide ad from European media.

The War Against Bugs, by Print Magazine — a Neocide ad from European media.

With all due respect to entomologists, there is nothing aesthetically pleasing about bugs (insects by any other name). These little monsters certainly have ecological significance, but don’t tell me they are fun to have crawling around. Hence, chemical manufacturers have made it their business to find he most efficient means of ridding the pests while retaining the fine upstanding species. Too bad that anything designed to kill will doubtless have ill effects on he eco-system. In he 50s DDT was the magic bullet against such varieties as various potato beetles, coddling moth, corn earworm, cotton bollworm  and tobacco budworms (eeeecccchhhh!). Then in 1972, the US Environmental Protection Agency curtailed all use of DDT on crops. The ban did not take hold in other countries until much later, and DDT was vociferously promoted through eerie calls to arms like this poster by Savignac.

Nota bene Mr. Heller does not claim DDT use against malaria-causing mosquitoes was ever banned.  He focuses instead on the promotion of DDT.

Naomi Oreskes on the political need for truth-telling in climate change

November 11, 2011

The too-often odious Huffington Post features an interview with Naomi Oreskes, one of the authors of Merchants of Doubt.

You should read the interview (and the book, if you haven’t yet):

[Kerry Trueman]:The real mystery, then, is how to persuade American skeptics that we face profound disruptions in our own lifetime and that of our children. Can you describe, in a lay-person friendly way, some of the scenarios we might anticipate?

[Naomi Oreskes]: Well, the best example is the “monster storm” that just hit Alaska, described by one media outlet as a storm of “epic proportions.” Climate change is underway, it is affecting American citizens, and it is going to become increasingly costly and disruptive.

We are no longer talking about the future, about people far away in time and space. We are talking about us, now. I think this is what Americans do not yet understand. But if current trends continue, they will soon. Climate change is all around us, and most of it is not good.

More, there.

Burt Folsom’s blog distorts history of DDT

October 13, 2011

I hadn’t thought Burt Folsom, author of FDR Goes to War, much of an ideologue, but a post at his blog makes me wonder about whether he is so grossly inaccurate on other things, too.

The post, written by Anita Folsom, said:

Fast-forward to the post-World War II period. In 1962, Rachel Carson published her best-selling text, Silent Spring, in which she protested the effects of pesticides on the environment.  Ten years later, DDT was banned.

Thomas Sowell points out that such bans, while passed with the best of intentions, have unleashed growth in the numbers of mosquitoes and a huge recurrence of malaria in parts of the world where it had been under control. The same is true of modern pesticides in the U.S. today.  One reason for the rise in the incidence of bedbugs, which bite humans and  spread disease, is that the federal government has banned the use of chemicals that were effective against such insects.

The issue is one of balance.  While it is every citizen’s responsibility to take an interest in a clean environment, it is also a responsibility to avoid over-zealous regulators who cause harm by banning useful chemicals.  Perhaps what is needed is a substance that will cause bureaucrats to leave citizens alone, both immediately and in the future.

Perhaps the trouble comes from relying on Thomas Sowell as a source here — on DDT and Rachel Carson, Sowell appears to be  just making up false stuff.

Thomas Sowell has come unstuck in history, at least with regard to DDT and malaria.

Thomas Sowell has come unstuck in history, at least with regard to DDT and malaria.

First, the “DDT ban” mentioned here was by U.S. EPA.  Consequently, it applies ONLY to the U.S., and not to any nation where malaria is a problem.

Second, the order banning DDT in the U.S. restricted the ban to agricultural use on agricultural crops, almost solely cotton at the time.  DDT use to fight malaria would still be legal in the U.S.

Third, the order banning DDT use in the U.S. specifically exempted manufacture of DDT — so in effect, the order more than doubled the amount of DDT available to fight malaria mosquitoes because all U.S. production was dedicated to export, specifically to allow DDT to be used to fight malaria.

Fourth, and probably most critically, it is simply false that malaria resurged when DDT was banned.  By 1972, malaria infections were about 500 million annually, worldwide.  Malaria deaths were about 2 million.  Even without U.S. spraying DDT on cotton crops in Texas and Arkansas, and to be honest, without a lot of DDT use except in indoor residual spraying as promoted by the World Health Organization (WHO), malaria infections have been reduced by 50%, to about 250 million annually — and malaria deaths were reduced by more than 50%, to fewer than 900,000 annually, worldwide.  WHO estimates more than 700,000 African children were saved from malaria deaths in the decade from 2001 through 2010.

Malaria deaths and malaria infections decreased after DDT was banned in the U.S., and continue to decline.

dsc4436-nosmile-300x200

Burt and Anita Folsom should have checked Sowell’s claims on DDT, rather than accepting them as gospel.

Fifth, while it is true that reports generally claim that DDT limited bedbug infestations in the 1960s, the truth is that bedbugs became immune to DDT in the 1950s, and DDT is perfectly useless against almost all populations of the beasties today, and since 1960, 51 years ago.  Also, the evolution to be immune to DDT primed bedbugs to evolve resistance to other pesticides very quickly.  DDT didn’t stop bedbugs, and lack of DDT didn’t contribute to bedbug infestations after 1960.

(Maybe worst, and odder, 111 people have been injured by pesticides used to control bedbugs, one fatally, in the past ten years.  Which is worse?)

Sixth, bedbugs do not spread disease, at least not so far as is known to medical and entomological science.

Sowell’s claims endorsed by Folsom are exactly wrong, 180-degrees different from the truth.  Sowell and Folsom are victims of the DDT Good/Rachel Carson Bad Hoaxes.

Since malaria has been so dramatically reduced since the U.S. banned the use of DDT, perhaps Rachel Carson should be given full credit for every life saved.  It’s important to remember that Carson herself did not suggest that DDT be banned, but instead warned that unless DDT use were restricted, mosquitoes and bedbugs would evolve resistance and immunity to it.  DDT use was not restricted enough, soon enough, and both of those pests developed resistance and immunity to DDT.

Ms. Folsom urges restraint in regulation, she says, because over-enthusiastic banning of DDT brought harm.  Since her premise is exactly wrong, would she like to correct the piece to urge more regulation of the reasonable kind that EPA demonstrated?  That would be just.

Good sources of information on malaria, DDT, and Rachel Carson and EPA:

Africa had a surplus of DDT from 1970s through 1990s, creating a massive toxic cleanup problem for today. This FAO photograph shows

Africa had a surplus of DDT from 1970s through 1990s, creating a massive toxic cleanup problem for today. This FAO photograph shows “TN before: 40 tonnes of 50 year old DDT were found in Menzel Bourguiba Hospital, TN.” DDT was not used because it was largely ineffective; but had any nation wished to use it, there was plenty to use.

Regulation works

September 21, 2011

Jim Weygand writing at the Twin Cities Daily Planet in Minnesota, defends government regulation:

For example there is not an industry today that is not safer than it was prior to the Occupational Safety and Health Act (OSHA) in 1970. Since OSHA was created in 1970, workplace fatalities have decreased 60% despite the more than doubling of the work force. Job related injuries and illness rates have decreased by 40%. And, yes government regulation has increased.

We can also credit the Environmental Protection Agency (EPA) for the restrictions on DDT that have brought our eagle and ospreys back from the edge of extinction as well as protecting us from its effects.

It has worked to prevent future Love Canal type environmental disasters. Government controls on nuclear power have prevented a Chernobyl disaster in this country.

Sideshow of DDT and malaria

August 23, 2011

Not exactly a DDT/Malaria carnival.  Just enough for a sideshow.

First, the controversy over use of DDT in Uganda continues, even as DDT is applied daily there.  This demonstrates that DDT remains freely available for use in Africa.  It also demonstrates that Africans are not clamoring for more DDT.

Uganda offers a key proving ground for the propaganda campaign against environmentalists, against scientist, against medical care officials, and for DDT.  Though malaria plagues Uganda today and has done so for the past 200 years at least, it was not a target of the World Health Organization’s (WHO) campaign to eradicate malaria in the 1950s and 1960s, because the nation lacked the governmental structures to mount an effective campaign.  DDT was used to temporarily knock down mosquito populations, so that medical care could be improved quickly and malaria cured among humans.  Then, when the mosquitoes came roaring back as they always do with DDT, there would be no pool of the disease in humans from which the mosquitoes could get infected.  End of malaria problem.

Plus, for a too-long period of time, Uganda was ruled by the brutal dictator Idi Amin.  No serious anti-malaria campaigns could be conducted there, then.

Uganda today exports cotton and tobacco.  Cotton and tobacco interests claim they cannot allow any DDT use, because, they claim, European Union rules would then require that the tobacco and cotton imports be banned from Europe.  I can’t find any rules that require such a ban, and there are precious few incidents that suggest trace DDT residues would be a problem, but this idea contributes to the political turmoil in Uganda.  Businessmen there sued to stop the use of even the small amounts of DDT used for indoor residual spraying (IRS) in modern campaigns.  They lost.  DDT use continues in Uganda, with no evidence that more DDT would help a whit.

Malaria campaign posters from World War II, South Pacific - Mother Jones compilation

Much of the anti-malaria campaign aimed at soldiers, to convince them to use Atabrine, a preventive drug, or to use nets, or just to stay covered up at night, to prevent mosquito bites. Mother Jones compilation of posters and photos.

Second, the website for Mother Jones magazine includes a wonderful 12-slide presentation on DDT in history.  Malaria took out U.S. troops more effectively than the Japanese in some assaults in World War II.  DDT appeared to be a truly great miracle when it was used on some South Pacific islands.  Particularly interesting are the posters trying to get soldiers to help prevent the disease, some done by the World War II-ubiquitous Dr. Seuss.  Good history, there.  Warning:  Portrayals of Japanese are racist by post-War standards.

Third, a new book takes a look at the modern campaigns against malaria, those that use tactics other than DDT.  These campaigns have produced good results, leading some to hope for control of malaria, and leading Bill Gates, one of the biggest investors in anti-malaria campaigns, to kindle hopes of malaria eradication again.  Here is the New York Times  review of  Alex Perry’s Lifeblood: How to Change the World One Dead Mosquito at a Time (PublicAffairs, $25.99).   Perry is chief Africa correspondent for Time Magazine.

This little gem of a book heartens the reader by showing how eagerly an array of American billionaires, including Bill Gates and the New Jersey investor Ray Chambers (the book’s protagonist), are using concepts of efficient management to improve the rest of the world. “Lifeblood” nominally chronicles the global effort to eradicate malaria, but it is really about changes that Mr. Chambers, Mr. Gates and others are bringing to the chronically mismanaged system of foreign aid, especially in Africa.

These three snippets of reporting, snapshots of the worldwide war on malaria, all diverge dramatically from the usual false claims we see that, but for ‘environmentalist’s unholy and unjust war on DDT,’ millions or billions of African children could have been saved from death by malaria.

The real stories are more complex, less strident, and ultimately more hopeful.


DDT fanatic a former Monsanto lobbyist?

August 4, 2011

Sometimes in unexpected places you stumble across a factoid that makes sense out of a lot of other factoids, turning them into enlightening, and perhaps useful, information.

Steven Milloy used to be a Monsanto lobbyist?  Is that accurate?

Among the allegations, that Monsanto aggressively protects its patents on seeds and other products sold to farmers, and that the company may not be above a bit of skullduggery to push farmers and, in this case, milk processors, to use Monsanto products.  Watch for Steven Milloy’s name to pop up in the last paragraph.  The site quotes a Vanity Fair  article on Monsanto from 2008.

Even if Monsanto’s efforts to secure across-the-board labeling changes should fall short, there’s nothing to stop state agriculture departments from restricting labeling on a dairy-by-dairy basis. Beyond that, Monsanto also has allies whose foot soldiers will almost certainly keep up the pressure on dairies that don’t use Monsanto’s artificial hormone. Jeff Kleinpeter knows about them, too.

He got a call one day from the man who prints the labels for his milk cartons, asking if he had seen the attack on Kleinpeter Dairy that had been posted on the Internet. Kleinpeter went online to a site called StopLabelingLies, which claims to “help consumers by publicizing examples of false and misleading food and other product labels.” There, sure enough, Kleinpeter and other dairies that didn’t use Monsanto’s product were being accused of making misleading claims to sell their milk.

There was no address or phone number on the Web site, only a list of groups that apparently contribute to the site and whose issues range from disparaging organic farming to downplaying the impact of global warming. “They were criticizing people like me for doing what we had a right to do, had gone through a government agency to do,” says Kleinpeter. “We never could get to the bottom of that Web site to get that corrected.”

As it turns out, the Web site counts among its contributors Steven Milloy, the “junk science” commentator for FoxNews.com and operator of junkscience.com, which claims to debunk “faulty scientific data and analysis.” It may come as no surprise that earlier in his career, Milloy, who calls himself the “junkman,” was a registered lobbyist for Monsanto.

If accurate, it’s a sort of “origins” story — I don’t think it explains Milloy’s current advocacy of DDT and almost all other things anti-environmentally-wise.  Nor does it explain Milloy’s penchant for making things up whole cloth.  Does Fox News disclose this anywhere?

It does suggest his dirty tricks chops against environmentalists and scientists get exercised more than I had imagined.

The story is an interesting and odd footnote in the debunking of the unholy War on Science that claims Rachel Carson was wrong, and DDT is harmless and right.

Poisoning the children: Study shows mothers give DDT to their children from breastmilk

July 29, 2011

Too many in the U.S. bury their heads in the sands about the issues, but researchers in Spain and Mozambique wondered whether indoor residual spraying (IRS) with DDT, to fight malaria-carrying mosquitoes, might produce harms to children in those homes.  They studied the issue in homes sprayed with DDT in Mozambique.

It turns out that young mothers ingest DDT and pass a significant amount of it to their children when the children breast feed.

The study itself is behind Elsevier’s mighty paywall, but the abstract from Chemosphere is available at no cost:

Abstract

Breast milk concentrations of 4,4′-DDT and its related compounds were studied in samples collected in 2002 and 2006 from two populations of mothers in Manhiça, Mozambique. The 2006 samples were obtained several months after implementation of indoor residual spraying (IRS) with DDT for malaria vector control in dwellings and those from 2002 were taken as reference prior to DDT use. A significant increase in 4,4′-DDT and its main metabolite, 4,4′-DDE, was observed between the 2002 (median values 2.4 and 0.9 ng/ml, respectively) and the 2006 samples (7.3 and 2.6 ng/ml, respectively, p < 0.001 and 0.019, respectively). This observation identifies higher body burden intakes of these compounds in pregnant women already in these initial stages of the IRS program. The increase in both 4,4′-DDT and 4,4′-DDE suggest a rapid transformation of DDT into DDE after incorporation of the insecticide residues. The median baseline concentrations in breast milk in 2002 were low, and the median concentrations in 2006 (280 ng/g lipid) were still lower than in other world populations. However, the observed increases were not uniform and in some individuals high values (5100 ng/g lipid) were determined. Significant differences were found between the concentrations of DDT and related compounds in breast milk according to parity, with higher concentrations in primiparae than multiparae women. These differences overcome the age effect in DDT accumulation between the two groups and evidence that women transfer a significant proportion of their body burden of DDT and its metabolites to their infants.

Highlights

► DDT increases in pregnant women at the start of indoor spraying with this compound. ► Rapid transformation of DDT into DDE occurs in women after intake of this insecticide. ► The DDT increases in breast milk of women due to indoor spraying are not uniform. ► Breast milk DDT content in primiparae women is higher than in multiparae women. ► Women transfer a high proportion of their DDT and DDE body burden to their infants.

“Primiparae” women are those with one child, their first; “multiparae” women are those who have delivered more than one child.

Without having read the study, I suggest there are a few key points this research makes:

  1. Claims that DDT has been “banned” from Africa and is not in use, are patently false.
  2. Spraying poisons in homes cannot be considered to have no consequences; poisons in in very small concentrations get into the bodies of the people who live in those homes.
  3. We should not cavalierly dismiss fears of harms to humans from DDT, because it appears that use of even tiny amounts of the stuff exposes our youngest and most vulnerable children.
  4. Beating malaria has no easy, simple formula.

Women, even poor women in malaria-endemic areas, should not have to worry about passing poisonous DDT or its breakdown products to their children, through breastfeeding.  The national Academy of Sciences was right in 1970:  DDT use should be stopped, and work should be hurried to find alternatives to DDT.

DDT “costly for Uganda”

July 22, 2011

To aid researchers looking for news from Africa on malaria and DDT, I’ll reproduce the entire news story from Uganda’s New Vision here.  Stories from this outlet frequently trouble me, in the unquestioning way writers take quotes from people where a more probing reporter might be more skeptical.  I am not sure of the status of New Vision among Uganda’s media, but it’s one of the few available to us here on a regular basis.

So, here’s the story, on DDT usage to fight malaria.  A couple of points we need to remember:  First, it’s clear that DDT is not banned in Uganda, and that DDT usage goes on, despite the crocodile tears of Richard Tren, Roger Bate, and the Africa Fighting Malaria, Astroturf™ group; second, this story relates difficulties in using DDT, including cost.  It’s not that the stuff itself is expensive.  DDT doesn’t work on all mosquitoes anymore, and it’s dangerous to much other wildlife.  Malaria fighters must do serious work in advance to be sure the populations of mosquitoes targeted will be reduced by DDT — that is, that the bugs are not immune to DDT — and care must be taken to control the applications, to be sure it’s applied in great enough concentrations, and only indoors, where it won’t contaminate the wild.

Here’s the story from New Visions:

DDT spraying costly for Uganda

Tuesday, 5th July, 2011

By Raymond Baguma and Gerald Kawemba

INDOOR residual spraying as a strategy to control malaria in Uganda is too costly and has affected the programme countrywide.

According to Dr. Seraphine Adibaku, the head of the Malaria Control Programme, this is why other malaria control strategies such as use of insecticide-treated nets and Artemisinin-based combination therapy are considered to be ahead of indoor residual spraying.

The Government is implementing the indoor residual spraying using pyrethrum-based and carbon-based insecticides in 10 malaria-endemic districts in the northern and eastern regions.

They include Amolatar, Apac, Kitgum, Kumi and Bukedea.

“About three million people in the 10 districts have been covered. We have reached over 90% of the population,” Adibaku said.

She added that under the Presidential Malaria Initiative, the budget for indoor residual spraying is sh4.5b per district each year.

Adibaku said it would be much cheaper if the ministry distributed insecticide-treated mosquito nets.

She, however, said indoor spraying has an advantage of delivering immediate impact compared to treated nets.

Adibaku disclosed that the health ministry is re-evaluating the effectiveness of using DDT for malaria control.

Dr. Joaquim Saweka, the World Health Organisation (WHO) resident representative in Uganda, said indoor residual spraying is highly effective and has been successful in Zanzibar and Rwanda.

He, however, added that it is capital intensive and needs a lot of money for each application done twice a year.

Saweka cited his previous posting in Ghana during which a town of 300,000 inhabitants required $3m for spraying each year.

He said with the high cost of spraying and low financial resources available, Uganda needs to prioritise usage of insecticide-treated mosquito nets.

Saweka added that Uganda is on the right path to eradicating malaria with efforts in prevention, diagnosis and treatment as well as universal coverage of insecticide-treated nets.

Health minister Dr. Richard Nduhura yesterday kicked off a nationwide programme to distribute 11,000 bicycles to health volunteers who will diagnose and treat malaria in homes. The programme is supported by the Global Fund.

It is part of the Government’s home-based management of malaria, which is part of a larger national strategy to deliver treatment to children within 24 hours after diagnosis.

 


PestAway: Exterminator deals with DDT, honestly

June 29, 2011

Here’s a cool breeze:  Pest Away Exterminators in New York explains, patiently, that DDT no longer works against bedbugs, and is otherwise ill-advised in most applications.

Try to find an error in this short post:

DDT

The truth about DDT…

  • It was highly effective when it was first introduced.
  • It nearly wiped out bed bugs in America.
  • It is NO LONGER effective in treating bed bugs.
  • It is more dangerous than people realized.

In 1939, DDT (Dichloro-Diphenyl-Trichloroethane) was introduced as the “miracle pesticide.” It was effectively used in military and civilian arenas to control lice, malaria, mosquitoes and bed bugs. It nearly wiped out all bed bugs in an allegedly “safe” method, but by the 1960’s, bed bugs had built up a resistance and potential immunity to DDT.

In 1962, Rachel Carson wrote Silent Spring, which essentially demonized DDT and helped launch the environmental movement. By 1972, DDT was banned in the USA, but DDT is still used very effectively in other countries to control Malaria. Although there is a public outcry to bring DDT back, it’s very unlikely that it would have any meaningful effect on controlling bed bugs.

Jeff Eisenberg founded the company in 1991, after a career with a large accounting firm.  It appears his training on the importance of accuracy in numbers, and honesty in facing tough situations, carried over to his new business.  Good on him.


Sowell wrong about DDT and Rachel Carson

May 16, 2011

Thomas Sowell bolloxed it up at National Review Online:

Who blames Rachel Carson, an environmentalist icon, because her crusading writings against DDT led to the ban of this insecticide in countries around the world — followed by a resurgence of malaria that killed, and continues to kill, millions of people in tropical Third World countries?

To which I responded:

Rachel Carson Homestead painting of Ms. Carson: Rachel Carson, a child of the Allegheny Valley, was a writer and an ecologist. There have been great writers whose descriptions of natural history and stories of the natural world charm and delight readers; and there have been scientists whose work excites the public attention. Rachel Carson rises to a heroic stature because her conscience called for action, not only words. (Painting by Minette Bickel)

Who blames Rachel Carson?

Only someone ignorant of malaria and DDT, or someone with a real political axe to grind.

Malaria did not “resurge” when DDT was banned on cotton crops in the U.S.  The U.S. ban did not extend to Africa, and DDT has never been banned in Africa nor most of Asia.

Malaria deaths have declined steadily over the past 50 years, generally as DDT use was reduced.  In 1959 and 1960, the peak years of DDT use, 4 million people died from malaria, worldwide.  WHO cut back on DDT use in 1965 when mosquitoes began showing serious resistance and immunity to the stuff, but by 1972, when the U.S. banned agricultural use of DDT (but continued exports), about 2 million people died annually from malaria.

Today, largely without DDT, malaria deaths are down to under 900,000 — a 75% reduction in deaths from peak DDT use.

Instead, since 2000 we’ve been using integrated vector management (IVM) to hold mosquito populations down, and we’ve been using improved medical care to treat humans who have malaria.  IVM and beefed up medical care was what Rachel Carson recommended in her book, Silent Spring, in 1962.

So, there is no cause-effect relationship between Ms. Carson and the U.S. ban on DDT, nor between that ban and malaria deaths.  In fact, there are fewer malaria deaths now than when DDT was used irresponsibly.

Carson was right.  It’s a good thing wise people listened to her.

Who knows what comments see the light of day over there?

How many times will conservative commentators of all stripes abuse the DDT/Rachel Carson story before they start getting it right?  How much does that skew their views from the accurate and wise view?


Heritage Foundation urges that Africa be poisoned

May 7, 2011

Oh, not outwardly anti-Africa, but stupidly so.

The extreme right-wing Heritage Foundation lashed out at health care workers and scientists fighting malaria in Africa and Asia for World Malaria Day, April 25 (HF’s post showed up on May 5).  If these malaria fighters really were smart, HF’s Jane Abel wrote, they’d just poison Africa with DDT instead of protecting children with bednets and working to improve medical care.  According to Abel, DDT is safe for everyone but mosquitoes, and more effective than anything else malaria fighters use — so they are stupid and venal, she asserts, for not using DDT.

Here’s her post:

Environmentalists celebrated World Malaria Day last week (and Earth Day the week prior). Meanwhile, thousands of African children died of malaria.

While these activists may make themselves feel like they’re saving the world, they are ignoring the best possible solution to Africa’s malaria problem: the use of DDT to wipe out the Anopheles mosquito.

Even though the World Health Organization resumed promotion of DDT in September 2006—realizing it had the best track record for saving the lives of 500 million African children—environmentalists are still emphasizing the use of bed nets instead. DDT treatments almost completely eradicated the disease in Europe and North America 50 years ago, but today an African child dies every 45 seconds of malaria.

Providing sub-Saharan Africans with bed nets has had far from acceptable success in delivering the amount of protection needed from mosquitoes. The World Bank touts the fact that 50 percent of children in Zambia are now sleeping under nets as a good thing, but what about the other half who are left defenseless against a killer disease? The Democratic Republic of the Congo had only 38 percent of children under nets in 2010.

One would question why, in the 21st century, people should have to live inside of a net in order to be safe from malaria. The world has a better solution, and it’s not the quarantine of African infants. Dr. John Rwakimari, as head of Uganda’s national malaria program, described DDT, which is nontoxic to humans, as “the answer to our problems.”

World Malaria Day 2011 had the theme of “Achieving Progress and Impact” and aims to have zero malaria deaths by 2015. If the world really wants to make progress and increase the number of lives saved from malaria, it needs to embrace for Africans the best possible technologies available today, and that means DDT.

Here’s my response, which I predict will not show up at HF’s blog in any form*:

DDT is toxic to humans — just not greatly and acutely so.  Ms. Abel should be aware of recent studies that indicate even limited, indoor use of DDT in the end produces a death toll similar to malaria.  But we digress on just one of the errors assumed by Ms. Abel.

If DDT could wipe out malaria-carrying mosquitoes, WHO would not have slowed or stopped its use in 1965, years before anyone thought about banning the stuff.  By 1965 it was clear that overuse of DDT in agriculture had bred mosquitoes that are resistant and even immune to DDTJonathan Weiner noted in his Pulitzer Prize-winning book, The Beak of the Finch, that today every mosquito on Earth carries at least a few copies of the alleles that allow mosquitoes to digest DDT as if it were a nutrient.

DDT cannot be a panacea for malaria.

Please do not forget that malaria is a parasite disease, and that mosquitoes are only the carriers of it.  To truly eradicate malaria, we need to cure the humans — and if we do that, the mosquitoes do not matter.  With no infected humans, mosquitoes have no well of disease to draw from.  Without infected humans, mosquitoes cannot spread malaria.

Only 38 percent of children in Congo sleep under bednets?  I’ll wager that’s twice the percentage of kids that were ever protected from malaria in Congo by DDT.  In actual tests in Africa over the past decade, bednets have proven to reduce malaria by 50 to 85 percent; DDT, on the other hand, reduces malaria only 25 to 50 percent under the best conditions.  If we have to go with one and not the other, bednets would be the better choice.  Nets are much, much cheaper than DDT, too.  DDT applications must be repeated every 6 months, at a cost of about $12 per application per house.  Nets cost about $10, and they last five years.  Nets protect kids for $2 a year, better than DDT; DDT protects kids for $24 a year (that’s 12 times the cost), but not as effectively as nets.

Also, it’s important to remember that DDT has never been banned in Africa.  DDT non-use is much more a result of the ineffectiveness of DDT in many applications — why should we expect Africans to throw away hard-earned money on a pesticide that doesn’t work?

Finally, it’s also good to understand that, largely without DDT, malaria deaths are, today, at the lowest point in human history.  Fewer than 900,000 people a year die from malaria today.  That’s 25% of the death toll in 1960, when DDT use was at its peak.

Ms. Abel assumes that all Africans are too stupid to use DDT, though it might save their children.  He states no reason for this assumption, but we should question it.  If Africans do not use DDT, it may well be because the local populations of mosquitoes are not susceptible; or it could be because other solutions, like bednets, are more effective, and cheaper.

Ms. Abel has not made a case that DDT is the best solution to use against malaria.  DDT cannot improve a nation’s medical care delivery systems, to quickly diagnose and appropriately treat malaria in humans.  DDT cannot make mosquitoes extinct, we know from 66 year of DDT use that mosquitoes always come roaring back.  DDT cannot prevent mosquitoes from spreading malaria as effectively as bednets.

Maybe, just maybe, as evidenced by the dramatic reductions in malaria deaths, we might assume that modern Africans and health care workers know what they’re doing fighting malaria — and they do not need, want, or call for, a lot more DDT than is currently in use.

It’s too bad Heritage Foundation fell victim to so much junk science, and that the otherwise august press release operation pushes the grand DDT hoaxes.  Just once, wouldn’t it be nice if these conservative echo chambers would, instead of recycling the old, wrong press releases of other conservatives, would do a little research on their own, and get the facts right?

*  It’ll be fun to watch.  I sent my response early, early in the morning while rushing to get a presentation ready, and I made a couple of egregious typos, including identifying Jonathan Weiner as “Stephen Weiner.”  If HF wished to embarrass me, they’d publish that one out of their moderation queue — but I’ll bet that even with my typos, they can’t allow the facts through.  Also, for reasons I can’t figure, some guy named Thurman showed as the author of HF’s piece on May 5.  So I had referred to Mr. Thurman instead of Ms. Abel.  Interesting technical glitch, or story, there.

Update, May 8:  As we should have expected, Steven Milloy’s Junk Science Side Bar also went on record as favoring the poisoning of Africa rather than the fighting of malaria.  Milloy makes claims that DDT will beat malaria (ostensibly before it kills all life in Africa), but his sources don’t support the claim.  Milloy is always very careful to never mention that, largely without DDT, the death toll from malaria is at the lowest point in human history.  Instead he notes that while malaria fighters promoted World Malaria Day, lots of African kids died of malaria.  That’s true, but misleading.  Because of the malaria-fighting efforts of those Milloy tries to impugn, far fewer African kids die.  Contrary to Milloy’s insane and offensive claims, it’s not alright that “only people” die.  Milloy asserts implicitly that, but for environmentalists, thousands or millions of children would survive that do not know.  That’s not true:  Because of the work that Milloy denigrates, millions fewer die.  It wasn’t environmentalists who overused DDT and rendered it ineffective in the fight against malaria, it was Milloy’s funders.  Follow the money.
