It is extremely challenging to know how many people are made
sick by food, which foods are at fault, which pathogens are most
widespread or dangerous, and where those pathogens entered the food
production system. In such a situation, where should research,
prevention and education efforts be directed? In this report, each step
in our complicated food production and supply system is described,
highlighting key points of vulnerability, and making it clear that
providing safe food is a shared responsibility.
