Neonicotinoid Pesticides

Debate between Martin Caton and James Paice

Tuesday 25th January 2011 Westminster Hall

[The Minister of State, Department for Environment, Food and Rural Affairs (Mr James Paice)]

I, too, congratulate the hon. Member for Gower (Martin Caton) on securing the debate. I say that seriously, despite the fact that I am in the position of having to reply.

None of us, as MPs, is unaware of the widespread concern, which has existed for a number of years, about our bee population. As the hon. Gentleman has rightly said, colony collapse disorder is not something new. Soon after the Labour Government were elected in 1997, I took part, in my earlier incarnation as Opposition spokesman challenging the Government, in a debate about bee health, on the specific issue of varroa. Unfortunately, the Government took no notice at all, and the varroa mite is now widespread—some would argue endemic—with the real long-term impact unknown.

The issue to which the hon. Gentleman has specifically drawn our attention—neonicotinoids—has recently returned to the headlines, and he is absolutely right to raise it. I certainly do not want to portray any suggestion of complacency on the matter. I will not go over the points, which we all fully understand, about the importance of honey bees and other non-vertebrate pollinators to our agricultural crop and horticultural industries. We must not be complacent; we must take things very seriously.

I appreciate that the hon. Gentleman was running short of time, but he concluded his speech by rushing off a long list of questions, which I am afraid I did not have time to write down. I will happily undertake to respond to them when I read them in Hansard, but forgive me if I do not reply to them all now. One thing that is probably blatantly obvious, but which underlines all this, is that all pesticides are toxic. Even the naturally occurring ones that are approved in organic farming are toxic at some level. The question is about the level of usage, the accumulation and the other factors that determine whether that toxicity is a threat. Of course we accept that neonicotinoids, as much as any other pesticide, are toxic at certain levels and in certain doses.

[Martin Caton]

The fundamental point is that we have very strong evidence that even in tiny doses those particular systemic pesticides contribute to the demise of invertebrate populations. That has to be of great concern, and it often cannot be picked up in field trials, on which, understandably, most of our assessment is based.

[Mr Paice]

I have taken the hon. Gentleman’s point on board. I understand it and will try to deal with it as best I can, because I certainly do not want in any way to imply that I am ignoring it or, to use his words, that the Government are being complacent about it. As he and others have said, the Government take pesticide regulation very seriously. All pesticides are rigorously assessed before they are approved for use, although I accept the point made by the hon. Member for Brighton, Pavilion (Caroline Lucas) that much of that information comes from the industry that developed them. However, the matter is open to public scrutiny after that by the advisory committee and the regulators, so if there were any implication that somehow those trial results were distorted intentionally, it would quickly come to light.

The conditions of use of a pesticide are set so that pesticides do not pose an unacceptable risk to people or to the wildlife in the countryside, which, of course, includes bees and other pollinators. I emphasise that there is a statutory code of practice about guidance to people who use pesticides on minimising the exposure of bees, including notifying local beekeepers 48 hours before their use.

We continue to fund research on pesticides and pollinators and in relation to monitoring the real-world impact of pesticides on bees. It is being considered as part of the wildlife incident investigation scheme, and we are adding those neonicotinoids that are not already covered to the programme of residues monitoring for honey.

The hon. Gentleman has rightly and understandably referred to the 2009 Buglife report. As he has said, Buglife basically took all the information that was available and reviewed it before publishing the report. The then Government fully reviewed that report and took advice from the independent Advisory Committee on Pesticides, and all the key research references were scrutinised and the implications considered. That involved drawing on the regulatory data set and any other publicly available information. The conclusion drawn at that time was that the Buglife report did not raise new issues—it would have been surprising if it had, given that it was simply going over all the information already held—and that it did not require changes to pesticide approvals.

[Martin Caton]

Is the Minister not concerned that we have discovered this month that the chemicals regulation directorate of the Health and Safety Executive, which was given the job, on behalf of the Government, of assessing the Buglife report, has still not completed its report and has not even completed collating the data? If we are really serious about dealing with this problem urgently, that is an appalling record. I do not blame the current Government alone—it is a failure of government.

[Mr Paice]

I shall write to the hon. Gentleman on the detail. His assertion is news to me, and I shall have to take it away with me. As he obviously appreciates, this is not my normal portfolio; I am covering for my noble Friend Lord Henley, who normally deals with bees.

What the Buglife report did do—there is no question about this—was indicate a gap in our knowledge on the effects of neonicotinoids on over-wintering bees. The point about that was right. We have supported the addition of studies on that issue to the European data requirements for pesticide regulation.

We continue to work with other regulators and to consider all the new evidence that emerges. We have discussed with James Cresswell of Exeter university his work on sub-lethal pesticide doses and bees, especially in relation to over-wintering. That is of interest, but as he himself fully acknowledges, questions remain about the environmental relevance of predominantly laboratory-based results. That is particularly relevant to the work to which the hon. Gentleman has referred by Henk Tennekes.

We are also, of course, aware of the work by Jeff Pettis in the United States, which is the origin of the article in The Independent to which the hon. Gentleman has referred. However, we have to recognise that Dr Pettis himself has challenged The Independent publicly about some of the assertions that it made. He has published the points on a website on that newspaper’s own blog. Forgive me, Mr Williams, but I think that I need to read out some aspects of that. Dr Pettis has stated:

“I noticed in your article that there is an implication that my research findings are perhaps being suppressed by the chemical industry. As the author of this study, I can tell you that the truth is that the review process on the paper has simply been lengthy, as is often the case, due to various factors, but that no outside forces are attempting to suppress this scientific information. The findings of an interaction between low level pesticide exposure and an increase in the gut pathogen Nosema were not unexpected; many such interactions are likely within the complex life of a honey bee colony. It is not possible to make a direct comparison with a lab study and what might occur in the field. Lab studies can give us insights into what may be occurring with beehives but we have yet to make this link. Honey bee health is complex and our findings support this. They do not provide a direct link to CCD colony losses but these results do provide leads for further study.”

I say that not to reject what has been claimed, but to put it into proportion. Even the work’s author rejects some aspects of the article that has caused so much understandable public concern recently.
