Thanks to the Minister, the sheep dip sufferers group now has access to documents including medical records from the poisons unit at Guy’s hospital, which show what many sufferers have known for years: there were long-term health impacts of using sheep dip. Will he meet us again so that we can act for those who still suffer?

The hon. Lady will be aware that I met her and others about a year ago, when we looked at this issue in depth. I subsequently went back through all the submissions that came from the chief veterinary officer in the early 1990s to establish precisely why we stopped using sheep dip, and it was not because of health concerns; it was because of a belief that it was not possible to tackle the disease. I note that she has now got the documents, but I simply say that the committee on toxicity looked at this issue exhaustively, examining 26 different studies over a period of more than a decade, and concluded that in the absence of acute poisoning there would not be meaningful long-term effects.

DEFRA monitors retail food prices through the consumer prices index. Year on year, food prices have continued to fall, with a 2.8% fall in the year to May 2016. We also monitor trends in household expenditure on food through the family food survey. Following a period of higher food price inflation, retail food prices have fallen by 7% since their peak in February 2014.

Last week I visited a very successful food supplier in my constituency that told me that it was already putting up its prices because of changes in the exchange rate hitting imports, and predicted food inflation of up to 8% within months, following the leave vote. Clearly there are real impacts now. How will the Minister respond to a spike in UK food prices, which is a crucial issue for consumers?

George Eustice Portrait George Eustice

As I explained earlier, one of the factors that has an influence on food prices is exchange rates. A number of analysts have been saying that in fact the pound has been unsustainably high against the euro for some time, caused by concerns about the weaknesses of the eurozone, and that the correction we have seen was overdue anyway. Exchange rates go up and down, but the crucial thing is that we have a competitive food supply industry in this country.

It is worth looking further at the science, because the committee’s statement was also endorsed by the medical and scientific panel, which is a sub-group of the independent Veterinary Products Committee. A cross-Government official group on organophosphates also endorsed it. It is worth highlighting some extracts from that detailed report. I have read the report, which is very scientific; I recommend it to anyone with an interest.

The report highlighted that, since 1999, 13 new papers have been published on the relation of low-level exposure to organophosphates and peripheral neuropathy, which added to the 13 studies already available at the time of the previous COT report. Having reviewed all 26 of those studies, the report concluded:

“The current balance of evidence suggests that there is no long-term risk of clearly demonstrable peripheral neuropathy from exposure to organophosphates”.

I know my constituent well and, having gone through his case in great detail, I am absolutely convinced that his health condition was caused by his exposure to sheep dip—the link is all too clear. Has the Minister also had a chance to review the independent academic research by Sarah Mackenzie Ross, an academic at University College London, who has reviewed all the existing studies and concluded that there is a considerable association between low-level exposure to organophosphates and impaired neurological function?

George Eustice Portrait George Eustice

I am aware that that report was reviewed by the Committee on Toxicity and that, in fact, part of the COT’s report does concede that there may be some effects in some cases. I will return to that. However, just to stick to the COT report, it highlighted that 22 investigations published since 1999 had looked for neuropsychological consequences of low-level exposure. When the committee looked at those, in addition to the nine published previously, it concluded:

“Overall, there is no consistent evidence that low-level exposure to organophosphates has adverse effects on any specific aspect of cognitive function. If organophosphates do cause long-term neuropsychological impairment in the absence of overt poisoning, then the effects, at least in the large majority of cases, must be minor and subtle.”

In relation to Parkinson’s disease, the report concludes:

“The overall balance of evidence from 11 studies suggests no increased risk of Parkinson’s disease from exposure to organophosphates that is insufficient to cause overt acute poisoning”.

However, it did acknowledge that

“a small elevation of risk cannot be ruled out.”

The report does acknowledge—this links to the point that the hon. Lady was making—that

“Despite limitations of individual studies, current evidence suggests that there is an excess of multiple neuropsychiatric symptoms in people who have been exposed to organophosphates at levels insufficient to cause overt acute poisoning. However, it does not support the existence of a specific syndrome of ‘chronic organophosphate-induced neuropsychiatric disorder’, as has previously been hypothesised.”

In its conclusion, the report states:

“Collectively, the evidence reviewed is reassuring. It suggests that exposures to cholinesterase-inhibiting organophosphates that are insufficient to cause overt acute poisoning do not cause important long-term neurological toxicity in adults”.

The reason why I have outlined those points—with long medical words that I am not used to pronouncing—in some detail is that it is important to acknowledge that there have been dozens and dozens of studies about this issue for more than 20 years. After the first COT report in 1999, the Government commissioned additional research into the subject, which was considered along with all the other evidence gathered since 1999 as part of the COT report last March. The committee has reached its conclusion based on the science.

I will try to make some headway, and then perhaps give way later on.

The hon. Lady will be aware that in November 2001 a group of farmers took a case to the High Court seeking damages for OP poisoning. In the event, the case was struck out, because the claimants could not prove that their symptoms were caused directly by exposure to OP dips. The decision was upheld by the Court of Appeal in November 2002.

I turn now to the issue of the HSE report that the hon. Lady mentioned. The report was commissioned in 1990 and published in 1991; there has been some discussion of whether it has been covered up, so it is important to note that it was published at the time. Since December 2014 there has been increased media attention on possible health effects experienced by people who used sheep dips, focusing on what was known about the substances by Government at the time, as sheep dipping was compulsory until 1992.

An FOI request was received from Tom Rigby of the Sheep Dip Sufferers Support Group at the beginning of February this year, seeking a copy of the HSE report. The HSE was initially unable to locate one; it informed Mr Rigby, who then stated that he held a copy from another source and further requested sight of any correspondence between the HSE and the MAFF in relation to the contents of the report. As no such correspondence was found, the HSE sent a nil response. However, a misfiled copy of the 1990 survey report was subsequently located elsewhere and passed on to Mr Rigby.

I know Mr Rigby still has outstanding FOI requests relating to some documents. The documents in question are HSE-commissioned reports into cholinesterase and the chronic effects of dipping sheep in OP products dating from the mid-1990s. Some are publically available and Mr Rigby has been pointed towards those; the HSE is currently looking into the status of others. To clear up any concerns, I am happy to say that we will place a copy of the 1991 report in the Library for hon. Members to look at.

It is clear that there are significant documented records from around 1993 that indicate considerable cross-Government work taking place on the subject of OP dips at the start of the decade. The 1990 survey appears to have been prompted by reports from farmers that they believed dips were making them ill. The research was focused on the extent to which operatives were exposed to organophosphates, the efficacy of their personal protective equipment and the dipping systems used. Although the report refers to known toxic effects of organophosphates, it does not focus on whether dips were causing ill health, nor does it look at whether dips can cause the long-term ill health that is the focus of the existing sufferer groups.

Will the Minister tell us why compulsory dipping was stopped in 1992?

George Eustice Portrait George Eustice
- Hansard - -

The Government recognise that organophosphates are potentially dangerous substances whose use needs to be controlled to minimise the risks to humans. Government policy is, and always has been, based on the best scientific advice. Safety warnings on the products reflected the known risks at the time. It is Government practice regularly to review the controls in line with the latest scientific advice and to carry out research to provide more information where required.

The 1991 report—it is important to recognise that that report was published at the time—was a survey of farmers who self-reported symptoms. We should bear two things in mind. First, it was not a scientific report; all the reports that the Committee on Toxicity has looked at are scientifically robust research projects. The other thing to note is that the focus of the 1991 report was whether farmers had the correct protective equipment to prevent acute poisoning. We must make a distinction between actual poisoning—organophosphates are poisonous substances that cause tetanus-like symptoms if acute poisoning takes place—and the separate issue of whether exposure to low levels of organophosphates that does not cause overt poisoning nevertheless contributes to long-term conditions. The conclusion of the report is that it does not. We must make that distinction. The report of 1990-91, which as I say was published at the time, was about the concerns about overt poisoning, not possible long-term conditions.

The sale and supply of OP sheep dips have been restricted to appropriately trained and certified users since 1995, reflecting concerns at the time about their toxicity. In addition, the Veterinary Medicines Regulations 2006 introduced a requirement for dipping to be supervised by a holder of a certificate of competence; that requirement remains in force.

Sheep scab is a severe disease with profound and sometimes fatal welfare implications for affected animals. There are currently still two sheep dips containing organophosphates that are authorised for use in the UK. There are other authorised veterinary medicines available to protect sheep against scab, but dips remain the most clinically effective treatments for the mite that causes it.

The Minister is being very generous in giving way, and I thank him for that. Will he agree to meet a group from the Sheep Dip Sufferers Support Group to go through some of the outstanding issues they have raised?

George Eustice Portrait George Eustice
- Hansard - -

Yes—I was going to conclude by saying just that. The hon. Lady put that challenge to me and I am more than happy to meet members of the group to discuss their concerns. I am also aware that she raised the specific issue of her constituent’s medical records, which she suggested were evidence that sheep dip might have contributed in his case. If her constituent agrees, I am happy to make that information available to the Veterinary Medicines Directorate, which regulates these products on our behalf, and the Health and Safety Executive, which has been the lead on the issue.

This has been a long-running saga. The interventions in the debate have shown that many hon. Members have constituents who associate their condition with OP sheep dips. I reassure Members that we are not hiding anything. The 1991 report was published at the time, but for the sake of completeness I am happy to ensure that we put a copy in the Library.

Question put and agreed to.
