Baseline knowledge survey of restaurant food handlers in suburban Chicago: do restaurant food handlers know what they need to know to keep consumers safe?
In the U.S., foodborne disease causes millions of illnesses annually, resulting in thousands of deaths. To reduce food poisoning, restaurant food handlers need accurate knowledge of food safety principles as a starting point for the outcome of optimal food safety behavior. The study described in this article determined food safety knowledge gaps among suburban Chicago restaurant food handlers. A cross-sectional survey of 729 food handlers at 211 suburban Chicago restaurants was conducted from June 2009 through February 2010. A 50-question survey was administered by a trained interviewer in either English or Spanish. Mixed-effects regression analysis identified risk factors associated with an overall food safety knowledge score. The mean overall knowledge score was only 72% and substantial knowledge gaps related to cross contamination, cooking, and holding and storage of food were identified. Spanish-speaking food handlers scored significantly lower than English-speaking food handlers (p < .05). Although certified food managers scored significantly higher than noncertified food handlers, their score was only 79%. These data provide targets for educational interventions to remedy knowledge gaps in food handlers in order to prevent food poisoning from restaurants.
