The World Health Organization (WHO) has developed five keys to food safety. This study aimed to determine the relation between the knowledge, attitude, and behavior of food handlers by determining the keys for Escherichia coli (E. coli) contamination on food served at a canteen. The research used a cross-sectional by interviewing 98 food handlers selling food at a campus canteen and by examining the E. coli samples in the sold food and beverages. The dependent variable in this study was E. coli contamination on food served at a campus canteen, while the independent variables were the knowledge, attitude, and behavior of food handlers, as developed from the WHO's five keys to improving food safety. Each independent variable was grouped into five sub-variables: key one, key two, key three, key four, and key five; these refer to the five keys to improving food safety. The data were analyzed using chi-square and logistic regression tests. The results showed that food handlers’ knowledge of appropriate cooking methods had a statistical relation with E. coli contamination on food served (p = 0.54 [p < 0.05]; OR = 2.990; 95% CI: 1.093 – 8.180). Furthermore, the food handlers’ attitude toward proper cooking methods had a statistical relation with E. coli contamination on food served (p = 0.58 [p < 0.05]; OR = 0.385; 95% CI: 0.157 – 0.944). There were two factors related to E. coli contamination on food served at the canteen: the food handlers’ knowledge of and their attitude toward the third key of the five keys to food safety.
