Bacterial contamination of hands increases risk of cross-contamination among low-income Puerto Rican meal preparers.

OBJECTIVE: To examine the association of microbial contamination of the meal preparer's hands with microbial status of food and kitchen/utensil surfaces during home preparation of a "Chicken and Salad" meal. DESIGN AND SETTING: Observational home food safety assessment. Before starting meal preparation, participants' hands were tested to estimate total bacterial and coliform counts and the presence of Campylobacter, Salmonella, Listeria, and Staphylococcus aureus (S. aureus). Microbiological testing was conducted on samples from kitchen/utensil surfaces, and on food ingredients obtained before and during meal preparation. PARTICIPANTS: Sixty Puerto Rican women residing in inner-city Hartford, CT. MAIN OUTCOME MEASURES: Total bacterial and coliform counts, and presence of S. aureus in target samples. ANALYSIS: Bivariate tests and multiple logistic regression. RESULTS: Participants considering food safety as "very important" were less likely to test positive for S. aureus on hands (P < .05). S. aureus on post-handling chicken, counter/cutting board, and salad was positively associated with S. aureus on participants' hands (P < .05). Coliform count on the counter/cutting board and sink was significantly higher at baseline when participants' hands tested positive for coliform before starting meal preparation. CONCLUSIONS AND IMPLICATIONS: Meal preparer's hands can be a vehicle of pathogen transmission during meal preparation.

Comparison between self-reported and observed food handling behaviors among Latinas.

The study was conducted to compare and identify the magnitude of differences between self-reported and observed food safety behaviors among women preparing a chicken and salad dish at home. The observed food safety practices also were compared according to sociodemographic variables and prior food safety education. Sixty Puerto Rican women who were the main meal preparers for their households were recruited in Hartford, Conn. Three household visits were made to (i) deliver food ingredients to prepare the chicken and salad meal, (ii) conduct household observation, and (iii) conduct a self-reported survey. The difference between self-reported and observed behaviors varied across food handling and sanitation behaviors. There was a high level of inaccuracy for socially desirable behaviors such as hand washing; the vast majority of participants reported practicing these behaviors but they were not observed doing so. Cutting board washing also was considerably overreported, questioning the validity of these self-reported data for regression analyses. There was a significant association (P < 0.05) between proper thawing method and prior food safety education, use of cutting board and higher income, and washing tomatoes and having a positive attitude towards food safety. Results revealed that overreporting errors must be considered when analyzing and/or interpreting data derived from self-reported food safety consumer surveys and that food safety education and positive food safety attitudes are associated with recommended food safety behaviors.
