Microbial contamination and good manufacturing practices in school kitchen

Abstract

AbstractThis study evaluated microbial contamination and good manufacturing practices (GMP) in school kitchens. Thus, the kitchen of four municipal schools have been assessed through microbiological analysis performed in their cutting boards (n = 12), kitchen sinks (n = 12), dish cloths (n = 12), hands of food handlers (n = 22), kitchen sponges (n = 12), milk (n = 10), and water (n = 10). A questionnaire was also applied to food handlers in order to access their profiles and get to know their daily practices inside school kitchens. The results this study showed that all samples (surfaces, cutting boards, kitchen sponges, milk, and water) were contaminated with heterotrophic bacteria. Staphylococcus aureus was found on the surface of sinks, dish cloths, cutting boards, and on the hands of food handlers. Fecal coliforms were found on sinks, water, and milk. Results from the survey reveal that food handlers know about GMP, but they do not perform these activities in school kitchens.Practical applicationsThe presented study shows that the schools there are failures in good manufacturing practices (GMP), which increase the risks of food contamination. In addition, we also showed microbial contamination on surface, cutting boards, kitchen sponges, and in food (milk and water) on schools which it make a risk for the development of foodborne diseases, since children have a relatively lower immunity than adults, additional safety measures are needed to protect them from foodborne pathogens and high microbial contamination in school. The microbial contamination in schools show that although the food handlers know about GMP, but there is a necessity for correct surface cleaning in food preparation to avoid foodborne illnesses proliferation in schools
