Long-term exposure to OP insecticides puts farmers at high risk of diabetes

18 Mar

Richard Bruce, who has suffered severely for many years following exposure to pesticides in the course of his work, sends news of research by a team from Madurai Kamaraj University, published in Genome Biology and is generously accessible to all readers. The paper may be accessed here.

Megha Prakash, in an article in ‘Down to Earth’, highlights the case of a 12-year-old boy reported from Mysuru, Karnataka. In 2011 the boy had eaten tomatoes from a field without washing them only a few hours earlier. Krishnan Swaminathan, an endocrinologist and president of the Coimbatore-based Kovai Medical Centre and Hospital, says that it was due to this impact of the chemical on the body’s insulin function that he first thought there could be a link between OP exposure and diabetes.

The observations in this and other cases mentioned in the article formed the premise of a study, conducted by a team from the Madurai Kamaraj University, to investigate the high prevalence of diabetes being reported from rural areas. Previous studies had shown a high prevalence of diabetes in rural Tamil Nadu, but this is the first one to link pesticide exposure to the disease.

Megha Prakash writes: “The researchers surveyed 3,080 people from seven villages in Thirupparan-kundram block of Madurai district. Participants were above the age of 35 years. Almost 55% of them were from the farming community and were, hence, more likely to be exposed to OPs. Based on the blood test results, it was found that the prevalence of diabetes among the farming community was three times higher (18.3 per cent) than that in the non-farming community (6.2 per cent), despite the low level of typical risk factors such as obesity, high cholesterol and physical inactivity”.

After countries started regulating or banning DDT in the 1970s due to its effects on the environment, OP insecticides came to account for 40% of the global pesticide market.

Ganesan Velmurugan, the lead researcher filed a Right to Information request against some of the state’s agricultural universities which listed these banned pesticides on their websites and even recommended their use.

But the response to his queries was not satisfactory. Kalpana Ramasamy, assistant professor at Agriculture College and Research Institute of the Tamil Nadu Agriculture University told Down To Earth that though agriculture universities are now recommending green-labelled pesticides (a green label means “slightly toxic”) to farmers, a complete ban will not be successful until an alternative to OP pesticides is found.

Prakash continues: “In India, pesticide use is regulated by the Central Insecticides Board and Registration Committee (CIBRC) and the Food Safety and Standards Authority of India (FSSAI). As of October 20, 2015, the CIBRC has completely banned two OP pesticides and regulated the use of four others. Of the four are methyl parathion, which is banned for use on fruits and vegetables, and monocrotophos, which is banned for use on vegetables”.

The study’s authors insist on the importance of spreading awareness about the effects of OP insecticides, especially in an agrarian country like India. “One must educate farmers about measures such as washing and soaking vegetables before use and wearing appropriate gear before spraying the pesticide. If awareness is not created now, in the next 10 years, the burden of this problem will be immense,” says Swaminathan.

But has effective protective clothing at last been designed? In one of many allegations,  sheep dip insecticide was alleged to contain chemicals which attacked the rubber in gloves making them porous. The effect was to render the protective clothing useless. Current advertisements say these suits only ‘reduce’ risk

Our informant Richard Bruce comments; “Of course OPs have been known to change blood sugar levels for a very long time but this confirms the diabetes link. Diabetes is rising in the general population in Britain because we are all exposed to these poisons in our food and environment.

 

 

 

 

An ‘epidemic’ of childhood tooth decay in the fluoridated Republic of Ireland

28 Feb

Background information: Ireland, the only country in the European Union with a nationwide mandate for water fluoridation -via the Health (Fluoridation of Water Supplies) Act 1960, which mandated compulsory fluoridation by local authorities. 3,250,000 Irish people receive artificially-fluoridated water.

Geren Island Water Treatment FacilityThe agent used is hydrofluorosilicic acid. Corrosive to most metals it eats through concrete and Hazmat suits (impermeable whole-body garments must be worn to handle it as a gas may be released which damages the lungs. This and other adverse health effects are listed by NIOSH (US government agency).

private member’s bill to end fluoridation was defeated in the Dáil on 12 November 2013. It was supported by Sinn Féin and some of the technical group and opposed by the Fine Gael-Labour government and Fianna Fáil.

Early in 2014, Cork County Council and Laois County Council passed motions for the cessation of water fluoridation. In Autumn 2014, Cork City Council, Dublin City Council and Kerry County Council passed similar motions.

irsih-jda-coverToday, Aaron Rogan in The Times reports that a study by University College Cork published in this month’s Journal of the Irish Dental Association found that 60% of the 347 Irish children who required dental treatment under general anaesthetic before they turned five needed teeth extracted.

Michaela Dalton, president of the HSE dental surgeons group describes it as an ‘epidemic of tooth decay’. “Juices and yoghurts are rotting babies’ teeth but are being sold as replacements for fruit. Sugary cereal bars are sold as healthy snacks. They’re labelled as no-added sugar and all-natural but they have concentrated fruit sugars, which are really acidic and rotting teeth” Dr Dalton said.

Another significant finding was that despite a long-established link between economic disadvantage and dental problems, there was no significant class difference for preschool children requiring treatment under general anaesthetic.

“Disadvantaged children have a higher risk of requiring a dental general anaesthesia in their lifetime; however, this is not occurring in isolation, with their equivalents in the higher social group also placing a strain on the system,” the study said.

The programme for government explicitly mentioned that preschool oral health intervention would save the taxpayer money – but the expensive water fluoridation programme already compulsory in Ireland is universally ‘sold’ as an oral health intervention. 

 

 

 

Agrichemical industry resists OP pesticides ban proposed by U.S. Environmental Protection Agency

19 Feb

In January EcoWatch reported that the U.S. Environmental Protection Agency (EPA) released its first nationwide assessments of the effects of three pesticides, all organophosphates, on endangered species. It found that 97% of 1,800 animals and plants protected under the Endangered Species Act are likely to be harmed by malathion and chlorpyrifos, two commonly used pesticides. The World Health Organization last year announced that malathion and diazinon are probable carcinogens.

TRAUDT AERIAL SERVICE

Another 78% are likely to be hurt by the pesticide diazinon. The results are the final biological evaluations the EPA completed as part of its examination of the impacts of these pesticides on endangered species. (See April draft here).

The three pesticides are all organophosphates, a class of insecticides which researchers at the University of California at Berkeley found in 87% of human umbilical-cord samples.

In 2015, the Environmental Protection Agency proposed to ban chlorpyrifos, a widely used insecticide sprayed on a variety of crops including oranges, apples, cherries, grapes, broccoli and asparagus. The pesticide, in use since 1965, was linked to illnesses among farm workers and neurodevelopmental problems in children. However, Dow AgroSciences and others in the agrichemical industry successfully resisted the proposal.

ecowatch-2-logoEcoWatch reports that Chemical & Engineering News (paywall) states the EPA is under a court order to make a determination about the use of chlorpyrifos by March 31 — about a decade after the agency initially failed to respond to a petition raising concerns about the chemical from environmental advocates.

Following these final evaluations from the EPA, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service will issue final biological opinions to identify mitigation measures and changes to pesticide use by December 2017 to help to ensure that chlorpyrifos, malathion and diazinon will no longer potentially harm any endangered species in the U.S. when used on agricultural crops.

“We’re now getting a much more complete picture of the risks that pesticides pose to wildlife at the brink of extinction, including birds, frogs, fish and plants,” said Nathan Donley, senior scientist at the Center for Biological Diversity:

“The next step will hopefully be some commonsense measures to help protect them along with our water supplies and public health.”

 

 

 

 

MSM downplays EU ban/delay on use of glyphosate, a probable carcinogen, for 18 months

9 Feb

TRAUDT AERIAL SERVICE

On February 8th, Agranet reported that the European Citizens Initiative (ECI) was launched in several European cities. It calls on the commission to propose a “ban on glyphosate, to reform the pesticide approval procedure, and to set EU-wide mandatory reduction targets for pesticide use”.

Its main objectives: Ban glyphosate-based herbicides, exposure to which has been linked to cancer in humans, and has led to ecosystems degradation; ensure that the scientific evaluation of pesticides for EU regulatory approval is based only on published studies, which are commissioned by competent public authorities instead of the pesticide industry; set EU-wide mandatory reduction targets for pesticide use, with a view to achieving a pesticide-free future.

In January this year, the Farmers Weekly recorded the European Commission’s registration of petition calling for a ban on the use of glyphosate, the key ingredient in Monsanto’s top-selling weedkiller. The initiative was formally registered on 25 January, starting a one-year process for the collection of signatures in support of the proposal. If the proposal receives the support of a million people from at least seven member states, the Commission will be obliged to consider a legislative response and provide justification for its decision.

The FW article adds that the European Chemicals Agency is undertaking a review into glyphosate and will consider whether it should be classified as a carcinogen by the EU. The review is due to be published this summer. It comes after a study, led by Michael Antoniou, at King’s College, London, linked glyphosate to non-alcoholic fatty liver disease in rats. Monsanto maintains glyphosate, when used according to label directions, “does not present an unreasonable risk of adverse effects to humans, wildlife or the environment”.

On 2nd February William Bowles blogged The EU has refused to give Monsanto’s glyphosate the green light. It’s delayed the decision for 18 months while glyphosate is re-evaluated” adding ruefully:

“(Banned) but not, it seems in Lambeth in London where the stuff is sprayed regularly on the pavements in my neighbourhood”.

 

 

Links between exposure to organophosphate pesticides and the onset of diabetes

26 Jan

As the government’s Food Agency is diligently warning the public of possible harm from burnt toast, will it heed a new concern raised by Indian scientists?  

British governments have a poor record when there is a conflict of interest between public health and large arms related/chemical/pharmaceutical companies.

Successive governments resisted acknowledging the harm done by early nuclear tests, Gulf War medication, thalidomide, mercury in infant vaccines and infected imported blood products – even, in the 70s and 80s compelling farmers to use organophosphate-based sheep dip and to this day encouraging the addition of a toxic chemical to drinking water.

The number of diabetes cases in Britain is causing concern; the Medical Research Council (above, a publicly funded government agency) reported in 2015 that there are 3.9 million people living with diabetes in the UK and quotes estimates that more than one in 16 people in the UK has diabetes (diagnosed or undiagnosed).

Richard Bruce sends a link to a report from India by Pallava Bagla published on Tuesday. It records that scientists at Madurai Kamaraj University in Tamil Nadu have found links between the use of pesticides and the high prevalence of diabetes in India (65 million people, second only to China).

They found the prevalence of diabetes in people regularly exposed to insecticides was three-fold higher (18.3 per cent) than in unexposed people (6.2 per cent).

Their results were published in the peer-reviewed journal Genome Biology. They also conducted experiments on mice, in which they found that exposure to pesticides upsets the micro-flora of the gut, leading to the onset of diabetes. Read quite a detailed account here: http://genomebiology.biomedcentral.com/articles/10.1186/s13059-016-1134-6

The team – which had been conducting the research in rural areas of South India – suggests that if people are continuously exposed to common OP pesticides like Malathion and Chlorpyrifos, they can get diabetes even when they do not have the other risk factors – obesity and high cholesterol.

ops-2-used-in-agric-india

This was a departure from traditional findings: the 3,080 people surveyed were physically active and did not have the better known risk factors for diabetes like obesity and high cholesterol.

OP pesticides are widely used in agriculture. Malathion is used even in urban areas to control mosquitoes and termites. They are known to affect memory and concentration, cause depression, headache and speech difficulties. The US Environmental Protection Agency (at risk under the new president?) publishes findings that these are amongst several classes of toxic chemicals that can harm children; researchers say OPs could be a contributing factor in learning disability and behavioural problems in children.

The scientists at Madurai Kamaraj University suggested that, in view of the high occurrence of diabetes in India, the use of OP (organophosphate) pesticides should be reconsidered.

 

 

 

Farewell Brenda Sutcliffe

23 Jan

We remember with affection and admiration, Brenda Sutcliffe, the gallant award-winning campaigner who, with her family, was seriously harmed by an OP pesticide. She died on January 18th.

brenda-award

In the picture above, we also recognise campaigners Tom Rigby (2nd left) and Peter Evans (far right – though not politically) in this picture.

brenda We celebrate Brenda’s vigorous campaigning and know that she would have been most interested in the next article – news of yet another organophosphate concern.

By coincidence a 2013 account of her work was top post this week. On the days her article was visited, the readers came from these countries on the left.

Read more about her work and that of other activists on the Sheep Dip Sufferers website set up by Tom.

 

 

 

It’s time to stop farming salmon

23 Jan

Quartz announces, “Lox lovers and sashimi devotees, prepare to shell out this year. According to the Nasdaq Salmon Index, salmon prices are at historic highs—and it’s all because of one tiny, nefarious little creature.

The culprit behind the rising price of salmon is about the size of an aspirin: a parasite known as the sea louse, or salmon louse. Acute outbreaks in Scotland and Norway this year have, er, eaten into the global supply of farmed Atlantic salmon. Norway, the planet’s biggest salmon producer, exported around 5% less by volume than in 2015. Globally, production fell around 9%.

Mark Macaskill reported in The Times that the use of toxic chemicals on Scottish salmon farms to fight sea lice has soared in the past decade, according to official data. Between 2006-16, farmed salmon production increased by 35% while the use of toxic chemicals to control flesh-eating lice rose 932%.

salmon-sea-lice

The sea louse is a parasite that kills millions of farmed fish every year cause serious fin damage, skin erosion and deep open wounds that are prone to infection. 

The latest figures, obtained under freedom of information from the Scottish Environment Protection Agency (SEPA), show that Scottish salmon farms used 45kg of chemicals in 2006 but this increased to 467kg in 2016. Since 2002, nearly four tonnes of chemicals have been dumped into the seas around Scotland

“Scottish salmon farming is fighting a losing battle against chemically resistant sea lice,” said Don Staniford of the Global Alliance Against Industrial Aquaculture. “The drugs don’t work anymore.

Treatments used by Scottish salmon farms included cypermethrin, a pesticide that was abandoned in 2012 after sea-lice developed resistance. Scientific studies have suggested that it impairs fertility in wild salmon. SEPA records also show that just over two tonnes of azamethiphos, an organophosphate insecticide  has been used in the past decade by salmon farmers. A paper published last month by scientists in Canada raised concern that azamethiphos poses a serious health risk to marine wildlife; tests on lobsters found repeated exposure can impair the nervous system and cause death.

Efforts are underway to reduce the use of chemicals to control sea lice. Scottish Sea Farms, one of the country’s leading producers of farmed salmon, recently bought a Thermolicer, a £4m delousing device. Fish are pumped into the machine and pass through heated water that kills the lice. Quartz reports, “the scalding-hot bath kills off the sea lice—and also, sometimes, the fish themselves. Last year, salmon-farming giant Marine Harvest inadvertently cooked 95,000 caged salmon with a thermolicer. Though that killed 95% of the sea lice, it also left the company with 600 tonnes of dead salmon to incinerate. Along with rampant salmon deaths from pesticide treatments, the thermolicer incident caused a 16% drop in the company’s Scottish salmon output for 2016”.

Just before Christmas, Salmon & Trout Conservation Scotland called for some of Britain’s leading supermarkets to ban the sale of farmed salmon from parts of Scotland where sea lice infestations are “rampant” and pose a threat to the survival of wild salmon and sea trout.
