Lord Krebs (CB)

My Lords, I will speak very briefly and in so doing declare my interest as a scientific adviser to Marks & Spencer. I do not want to repeat what has been said, and I agree with the noble Lord, Lord Lansley, that much of the debate this evening has been a repetition of what we heard in Committee and on Report of the primary legislation. However, I just want to recap on the question of mandatory labelling, which has cropped up in a number of noble Lords’ contributions. The noble Lord, Lord Rooker, made the point that it would be very difficult to enforce mandatory labelling because you cannot tell the difference. That is the whole point: precision-bred organisms, as defined in the Bill, are organisms that could be produced by conventional breeding. So, if I were an enforcer, I would not know where to start. My noble friend Lord Cameron of Dillington made the point that in due course, these gene-edited, precision-bred products will be pervasive in the food chain. Once there is a wheat that could grow without application of pesticides or could grow more effectively in our climate, it will become pervasive in the food chain. So where does the labelling start and end? My third point, which was made by my noble friend Lady Freeman, is that it may be up to retailers, on a non-mandatory basis, to label the benefits. So: “Here is a tomato that is better for you”—and it may be labelled like that. It is not the process but the end product that matters. But if we insist on the process, and I agree with what the noble Earl, Lord Caithness, said, we should be equally willing to put labels on conventionally bred organisms—apples, bread or other products—that says, “This product has been produced by bombarding gametes with nuclear radiation”. That is a process: it is the equivalent of gene editing but on the other side of the fence. My final point is about cross-contamination. If I were a farmer producing gene-edited wheat, I would be really worried about cross-contamination from the neighbouring organic farmer. I would want guarantees that that organic farm was not going to contaminate my gene-edited crop. At the same time, the organic farmer is looking at me and saying, “I don’t want his stuff contaminating my crop”. It is in the interests of both sides to figure out ways of reducing or minimising the risks of cross-contamination. So it is not a one-way street, and I strongly support this secondary legislation.
