uring pregnancy, a woman's immune system is compromised and she is at an increased risk of infection and illness. 1 Therefore, safe, proper food handling and preparation techniques that minimize the risk of food-borne illness are even more important during pregnancy than during other periods of adulthood. It is estimated that pregnant women are 20 times more likely than other women of reproductive age to contract listeriosis, a food-borne illness caused by Listeria monocytogenes. 2 While the symptoms of listeriosis tend to mild and flu-like for the mother, L. monocytogenes can be passed via the placenta to the fetus, where the consequences are more serious. 3 Depending on when fetal infection occurs, listeriosis can lead to spontaneous abortion, premature delivery, stillbirth, or neonatal meningitis and septicemia. 3 The 2008 outbreak of L. monocytogenes in deli meats reminded Canadians of the inherent risks in our food supply. The first known Canadian listeriosis outbreak occurred in 1981, affected 34 pregnant women, and resulted in 5 spontaneous abortions, 4 stillbirths, and 23 seriously ill premature and full-term infants. 4 Since that time there have been eight additional outbreaks, three of which have involved pregnant women. 5 The most recent outbreak involving pregnant women was in the fall of 2008. 6 Of the 38 confirmed cases, 13 women were pregnant, 5 delivered prematurely, and 3 lost their babies at birth or shortly thereafter. 6 Considering the seriousness of the consequences associated with fetal listeriosis and that more than 380,000 babies were born in Canada last year, 7 the importance of educating pregnant women about the dangers of high-risk foods and ways to minimize foodborne illness risks cannot be overstated. However, in Canada, it is not clear who is responsible for counselling pregnant women on listeriosis or other food safety issues during pregnancy such as Salmonella, Vibrio, and Escherichia coli O157:H7 infections or the importance of regulating fish consumption to limit mercury exposure. 8 Thus, it is possible that many women are not receiving proper guidance on how to minimize unnecessary food safety risks for themselves and their babies. Food safety knowledge for pregnancy An Australian study of 562 mothers revealed that only 59% received information on food safety during their pregnancy. Fortytwo percent received information directly from their doctor or midwife and 8% from prenatal education classes. 9 When asked to identify foods that should be avoided during pregnancy because of listeriosis, mothers correctly identified soft cheeses (81%), chicken liver pâté (68%), deli meats (64%), cold smoked salmon (61%) and coleslaw (50%). Interestingly, 72% of mothers incorrectly identi
