Evaluation of food safety knowledge, attitudes and self-reported hand washing practices in FOODSAFE trained and untrained food handlers in British Columbia, Canada

The purpose of this study was to examine food safety knowledge of trained food handlers certified under the FOODSAFE training program in British Columbia, Canada and to evaluate food safety knowledge, attitudes and self-reported hand washing practices in trained and untrained food handler groups. Data gathered in a telephone survey demonstrated knowledge scores significantly decreased in FOODSAFE trained workers over a 15 year period post-certification. Knowledge scores were significantly higher in trained compared with untrained food handlers. No differences were noted between groups based on sex. Supervisory status and years of experience resulted in improved knowledge scores in both trained and untrained groups, but increasing age was important for improved knowledge in only the untrained group. Food handlers' place of employment and level of education were also associated with significantly improved knowledge scores. FOODSAFE trained food handlers' reported significantly better hand washing practices and attitudes compared with the untrained food handler group. These results support a requirement for recertification of trained food handlers and demonstrate a need for education of untrained food handlers with a food safety training program such as FOODSAFE.
