My hon. Friend will remember that I had some involvement in the problems at that time. It was important early on
to establish a threshold for contamination/adulteration that made sense. Otherwise, we would have been in the absurd position of testing every piece of meat and finding that it was contaminated simply because somebody in the room might be shedding human DNA or because the meat had been sitting in a butcher’s shop where beef or pork sausages were not in separate airtight compartments. The level of the threshold, it seems to me, was one of the most important early advances we made in understanding the issue and ensuring that we were not attacking the wrong problem.
