INTRODUCTION: Food safety has become increasingly importance worldwide. Food borne diseases have impacts on public health and socioeconomic factors, accounting for hospital costs in treatments and hospitalizations. People involved in food production can be carriers of enteroparasites and contaminate food, causing food borne diseases OBJECTIVE: The aim of this study was to investigate the presence of enteroparasites in food handlers in Ribeirão Preto, SP, proposing measures to ensure the sanitary quality of food. METHODS: From July to December 2000, 429 food handlers (248 women and 181 men), aged between 16 and 77 years, underwent coproparasitological analysis as a mandatory professional requirement. Fecal samples were analyzed by the Kato's and spontaneous sedimentation methods. Cryptosporidium spp oocysts were investigated in 7.0% of diarrheic fecal samples using the formalin-ether concentration technique. RESULTS: The results showed enteroparasitosis in 33.1% of food handlers, including 20.0% cases of multiple parasitic infections. A higher prevalence of infections (68.0%) was detected among the individuals involved in direct food handling activities. CONCLUSIONS: Considering these results, it is necessary to provide sanitary education and training to food handlers, and to implement the method of Hazard Analysis and Critical Control Points (HACCP) in all stages of the food chain so as to ensure food safety for consumers.
