Nanotechnologies and Food: Science and Technology Committee Report

Baroness O'Neill of Bengarve Excerpts

Tuesday 13th July 2010 Lords Chamber

[Baroness O'Neill of Bengarve]

My Lords, I, too, was privileged to serve on the Sub-Committee on Nanotechnologies and Food. Not being a scientist, I found it challenging. Being chaired by the noble Lord, Lord Krebs, it was also fun. With the excellent support that we received both from the Clerks and our specialist adviser, Professor Stephen Holgate, I think that I ended up understanding a certain amount about nanotechnology. What I think I understand very clearly is why this is an important topic, and one where the new Government will have reason to take action on various fronts.

The debate takes place at a moment that may be either awkward or advantageous—I am not sure which—but it is at the very least unplanned. The Select Committee’s report on nanotechnology and food addressed a world in which the Food Standards Agency was the UK’s lead body with responsibility for food standards and safety. The Government’s response to the Select Committee’s report is the response of the previous Government, who showed considerable confidence in the Food Standards Agency, which they asked to co-ordinate that response.

It is far from clear that this confidence is shared by the coalition Government. Over recent days there have been numerous reports that the Government plan to abolish or dismember the Food Standards Agency. Headlines have ranged from the Mirror’s rather trenchant:

“Food Standards Agency watchdog is chewed up by ConDems”,

to the Atlantic’s more political—indeed, conspiratorial —revelation:

“How the Food Lobby Killed Britain’s FDA”.

That is of course not a misprint, and it is inaccurate to think that the Food Standards Agency corresponds exactly to the Food and Drug Administration in the US.

Perhaps inevitably, some commentators have begun to wonder whether the Government are unsure which FSA they want to reform and which they want to abolish. We are tonight concerned only with the Food Standards Agency. The Government have indicated that they have not yet reached a decision on what might be done. The Minister confirmed that this afternoon in responding to a Question from the noble Lord, Lord Krebs. However, there is a widespread sense that the Food Standards Agency may be in some danger. The main question—which I hope the noble Earl can answer—is: how far do the Government plan to stand by a response that is not of their making? Which commitments do the new Government seek to shed and which do they seek to strengthen? The coalition Government should welcome many of the committee’s recommendations and endorse much of the previous Government’s response. This was, after all, a report about cutting-edge research, emerging technologies and their application in a domain of daily concern to everyone. It is not an area from which any Government would wish to bow out.

The questions that are raised by the introduction of new technologies—in particular very novel technologies that are not well understood—into food processing link basic and applied scientific research, knowledge transfer, innovation in manufacturing, the fate of a very large part of the British economy and the daily consumption of food by each one of us. The human and economic consequences of getting matters wrong could be large, ranging from failure to adopt food technologies that may be useful for human health, to failure to co-ordinate work on the scientific basis of nanotechnologies, to failure to build on the achievements of UK scientists, to a considerable loss of competitive advantage by the UK food processing industry, not to mention the possibility of failure to adjust regulation to focus accurately on the risk assessment that will be needed.

I am no friend of excessive regulation, and like many who have run a small institution, I know its costs all too well. However, there are cases in which laissez-faire and market solutions will not work. Public health is a public good, often not achievable by the interplay of market forces and consumer choice alone. The long-running battle between the FSA and the food industry over labelling illustrates—if it illustrates nothing else—that there are those in the food industry who prefer to communicate, or at least pretend to communicate, in ways that demonstrably are not understood by many consumers and indeed may not be comprehensible to many consumers. Mere labelling will not be enough to secure public acceptance of food products containing nanoparticles, despite the fact that nanoparticles are found in many naturally occurring products, including traditional foods—and the sub-committee was told that ricotta cheese contains many of them. We need a more thoughtful approach.

I have mentioned some examples of matters that bear on success or failure in the use of nanotechnologies, in particular in the food industry, where, it seems to me, only Government and regulatory action can hope to be effective either in protecting consumers or in supporting the British food industry. First, there is the matter of securing agreement, including international agreement, on definitions. The noble Lord, Lords Krebs, has already mentioned this topic with his great expertise. There are those who seek to define nanoparticles simply in terms of their dimensions. Nanoparticles, they propose, should be defined as particles of which at least one dimension falls below an intrinsically arbitrary threshold of 100 nanometres. However, the reason why some nanoparticles are of interest to the food industry, as they are to other industries, is not simply that they are very small, intriguing as that may be, but that some, though not all, particles at nanoscale have functionally distinctive properties, so may offer nutritional or commercial advantages, though may also require additional risk assessment. Will the Government ensure that the regulatory definition of nanomaterials that must be built into the formulation of any requirements for additional risk assessment is functional and not merely metric? Will they work towards trying to ensure that EU regulation also settles on a functional and not a merely metric definition?

Secondly, there is the matter of ensuring that communication by companies to consumers is adequate. There has been a great deal of emphasis on communication by labelling. But I think that we all know that communication is genuine only where it is actually understood by the relevant audiences—in this case consumers. Transparency by itself is never enough. It is not enough because the fact that information is made available does not ensure that it will be noted, understood or taken into account by relevant audiences. Excessive reliance on consumer choice—when that choice is supposedly informed only by incomprehensible data delivered in the smallest print, on colourful packaging designed to emphasise other, more glorious matters—is not genuine communication. Only government can ensure that food marketing achieves genuine rather than pretended communication with consumers.

There are a number of important audiences for genuine communication in this area. There is the matter of ensuring that communication between companies about research at a precompetitive stage supports, rather than suppresses, the understanding of important information. There is the matter of ensuring that communication by food companies with the wider public is adequate. Possibly the most worrying finding of the sub-committee, alluded to by both previous speakers, is that food companies appear to be secretive about the research that they are conducting. They do not, as far as we could discover, have in place modes of exchanging information on precompetitive matters, and they do not foster public engagement.

The sub-committee was well aware that this secrecy may reflect awareness of the problems created just over a decade ago by a non-UK company when it trumpeted the advantages of its products incorporating the then new technology of genetic modification into plant varieties without adequate communication with, and in particular without listening to, the public. We all know the disaster that resulted for UK and EU plant-breeding companies. We all know that we now live in a bubble in which we pretend that the foods we eat contain nothing that is genetically modified—except of course by traditional methods such as evolution and selective breeding of animals and plants—although non-EU countries have adopted many of the genetically modified crop varieties without harm and to their advantage. But the way to avert another disaster for another British industry is not to be economical with communication about research on products that incorporate engineered particles at the nano scale. What will government do to seek better communication among companies and between companies and the wider public, with a view to fostering an effective and mature discussion of the real issues that need to be addressed if engineered particles at the nano scale are to be incorporated into our food?
