Bad decisions on organophosphates – 28: why doesn’t government act on reports by DEFRA, the Lancet and toxicology research, 1999-2012?
Has the state exposed sheep farmers and soldiers to OP poisoning?
Dr Virginia Harrison (Open University), co-author of the most recent UK study (cover opposite) on the subject very briefly summarised the problem a few days ago; a number of occupational groups have expressed concern that their health has been affected by exposure to organophosphates, including sheep farmers, who between 1988 and 1991 were required by government to dip sheep yearly in pesticide formulations containing OPs. Between 1985 and 1998 more than 600 reports of ill health following exposure to sheep dip were received by a government adverse reaction surveillance scheme.
Despite this, the government appears to have ignored research findings ranging over the last fifteen years, including:
The Lancet : Volume 354, Number 9173, 10 July 1999 85-172, page 133 … Prolonged, low-dose exposure to organophosphorus sheep dips is linked with chronic ill-health—the most risky occupational activity seems to be handling of concentrated pesticide. These are the main findings of a report published by the Institute of Occupational Medicine (IOM; Edinburgh, UK).
The Lancet Neurology, Volume 3, Issue 12, Page 702, December 2004. A top-level US advisory Panel has reported that the neurological symptoms associated with Gulf War syndrome are probably caused by low-level exposure to various toxins that soldiers were exposed to during the war in 1991. The findings of the Panel, which was appointed by the Department of Veterans Affairs (VA) in 2002, support those of an ongoing series of reviews undertaken by the Institute of Medicine (IOM).
The finding of one of these reviews – well worth reading – was that evidence strongly and consistently indicates that one of the Gulf War neurotoxic exposures causally associated with Gulf War illness was pesticide use during deployment. Evidence includes the consistent association of Gulf War illness with pesticides across studies of Gulf War veterans, identified dose-response effects, and research findings in other populations.
Research published by DEFRA revealed the extent to which even low level exposure to organophosphate (OP) sheep dip appears to have caused health problems in farmers. An extensive study involving 132 farm workers with a history of using OPs before 1991 found they are suffering today from a range of physical, mental and emotional problems. Dr Mackenzie-Ross, of University College London, said “Defra’s advice should stress OPs should be a last resort and that other chemicals can be used.”
Defra appeared to dismiss its findings, commenting: “The results of this report do not definitively demonstrate organophosphates cause chronic ill-health, but suggest that a relationship may exist.” It ruled out using taxpayers’ money to compensate victims ‘when the current independent advice is that a link between long-term, low-level OP exposure and ill health has not been proven’.
March 2012: VMD and OGOP – not a dynamic duo:
An update from the government’s Veterinary Medicines Directorate, informed the Official Group on Organophosphates that the VMD awaits new residues data from the manufacturer of Osmond’s Goldfleece. The last update from the manufacturer suggests that their report may be ready by April 2012. The VMD reminded OGOP that the change was separate from the issue of whether the use of OPs was linked to ill-health in humans. ACTION: OGOP Secretariat to arrange the next meeting for October 2012 if the OP review was completed. Searches show no sign that the review has been completed or an October meeting held.
Earlier this month the farming press reported that a systematic review of the literature carried out by researchers at UCL, in London and the Open University, with the same lead author, found that low exposure to the chemicals damages ‘neurological and cognitive function’. The research was published in the journal Critical Reviews in Toxicology.
Powerbase reports that some prominent European Food Safety Authority regulators have conflicts of interest, holding positions in organisations that are funded by the same companies whose products they are supposed to regulate – pesticides, genetically modified (GM) foods, and food contaminants.
This report shows that over a period of many years, influential EFSA managers and regulators have been heavily involved with a US-based organisation called the International Life Sciences Institute (ILSI), which is funded by multinational pesticide, chemical, GM seed,and food companies. The independence of EFSA’s risk assessment processes on pesticides and food safety has been seriously compromised by its close involvement with industry, chiefly represented by ILSI.
Is our government also closely involved with industry as we so often report?
Are they also bowing to the industry’s interests at the expense of many, including farmers, soldiers and pilots?
