UK Stomach bugs cause 11 million working to be lost each year according to joint research by the FSA and the University of Manchester. With Campylobacter and Norovirus being the two major causes. There has already been interest shown in testing food products for viruses and this type of data will only add to the pressure for looking at testing food for viruses. It also emphasises the FSA campaign for reducing Campylobacter levels in raw poultry in the UK.
