That is a tough question, partly because all the time we are seeing pathogens emerging. For example, we have E. coli 0157, which not even been heard of 30 years ago. We have Cryptosporidium, which had not been heard of 25 years ago. We are being presented with new challenges all the time. If we look at the more conventional pathogens, however, such as salmonella, if anything British farming is doing a good job. Salmonella-contaminated eggs have virtually been eliminated under that scheme, and the quality of the poultry sold by supermarkets appears to be a lot better. These are good things.
