 PHO Grand Rounds: Listeriosis in Ontario

In 2008, Ontario experienced the largest listeriosis outbreak ever recorded in the province. Since then, the Ministry of Health and Long-Term Care, Public Health Ontario and local public health units have been collaborating with the Public Health Agency of Canada to conduct enhanced surveillance for this disease.

Surveillance of enteric diseases is one of the core mandates of Public Health Ontario and is the primary means of obtaining better data on behavioural risk factors in order to inform prevention and control measures.

This presentation provides a summary of listeriosis in Ontario from 2008 to the present. We focus on behavioral risk factors that have been identified among cases over this time period. We also highlight a recent Health Canada study which examines consumer behavior, knowledge and attitudes regarding listeriosis.

We conclude with a discussion of potential opportunities to address health behaviors that can reduce the risk of acquiring listeriosis.
