Introduction Throughout the world food safety and quality is a topic of public concern. Wellpublicized and widespread foodborne disease outbreaks have created an awareness of potential threats to human health from food products. Much of the concern about foodborne disease is related to the changing nature of outbreaks. Traditionally, outbreaks of foodborne disease were acute and highly local in nature, often following a social event in a community. The more recent events have been the result of low-level contamination of widely distributed commercial food products. Instead of a local food handling error, recent large epidemics have generally been the result of an error in the industrial chain of food production.
