Exploring historical Canadian foodborne outbreak data sets for human illness attribution.

摘要: Human illness attribution has been recently recognized as an important tool to better inform food safety decisions. Analysis of outbreak data sets used for that purpose. This study was conducted explore the usefulness three comprehensive Canadian foodborne covering 30 years estimating in cases gastrointestinal illness, providing estimates from a historical perspective. Information concerning microbiological etiology and vehicles recorded each standardized between sets. The agent-food vehicle combinations were described analyzed changes over time by using multiple correspondence analysis. Overall, 6,908 outbreaks available decades (1976 through 2005), but agent identified only 2,107 these outbreaks. Differences found distribution cause, vehicle, location or size Multiple analysis revealed association Clostridium botulinum wild meat C. seafood. also highlighted generated most up-to-date values salmonellosis (29% associated with produce, 15% poultry, other than pork, beef), campylobacteriosis (56% poultry 22% dairy products fluid milk), Escherichia coli infection (37% beef, 23% cooked multi-ingredient dishes, 11% pork). Because inherent limitations this approach, main findings should be considered policy making. use human approaches may provide further clarification.
