In choosing to focus on emerging microbiological food safety issues, IFT hoped to emphasize the complex, everchanging nature of microbiological food safety. Pathogens evolve, people’s behaviors and susceptibilities differ and change, and production and processing developments modify the microbial environment. We cannot expect to “solve” the problem of microbiological food safety to the point of having a zero-risk food supply. On the other hand, we have the opportunity to look forward and address issues before they become pervasive.
