Evaluation of food safety training on hygienic conditions in food establishments

Food handlers' training is fundamental in order to ensure the safety of the foodstuff. However, the success of training programs that provide only information is unclear and changes in improper food practices are not usually achieved. Food training programs based on theoretical as well as practical activities have been revealed as an important tool in which food handlers can put information into practice. Thus, the objective of this study was to assess the influence of food safety training, based on both theoretical and practical approaches, on the microbiological counts of food contact surfaces, food tools, food equipment surfaces and hand washing in canteens and cafes of one university campus. After food safety training, total plate counts decreased about 60% in the case of canteens and almost 45% in cafes while moulds and yeasts decreased approximately 65% in canteens and 55% in cafes. In terms of location, the microbiological reductions observed were higher for food equipment in canteens and for food tools in cafes. The microbiological counts of food handlers' hands decreased after both food safety training and disinfection. Food safety training influenced the reduction of overall microbiological parameters. Parametric t-tests (after vs before training) indicated that reductions were statistically significant before and after disinfection for total plate counts. The decrease observed for total coliforms and Enterobacteriaceae, were statistically significant only before disinfection. The food safety programs cannot be based entirely on a theoretical approach but also on adequate training which includes a practical approach. The success of the microbiological reductions in the study was associated to the practical lessons which let the handler put into practice the knowledge acquired in the theoretical part.
