[Efficacy and critical implications of food handlers' professional training: analysis of an experience].

UNLABELLED

Our study aimed at both assessing the efficacy of the same training course in different contexts and training course repeated in the same context. We examined the most critical aspects, on which to develop further aimed course. In 1998 the Laboratory of Environmental Microbiology of the Institute of Hygiene (UCSC) has implemented 2 professional training courses both for food handlers of a refectory (course A) and of a hospital canteen (course B). Two years after a following course (C) in the hospital canteen. At the beginning and at the end of every course a questionnaire of 25 questions has been gathered in five areas. The data drawn by the questionnaires have been compared using the percentage of exact answers before and after the course. Correct answers beginning and end course: A 89% and 94%, B 68% and 77%, C 76% and 78%. The correct answers beginning course C and end course B are not significatively different (p = 0.1963). Critical areas of the C and B courses have been "microbiological risks" and "correct temperatures"; at the end of the training both the areas had sensitive improvements (C 40% to 59%, 60% to 78%-B 31% to 69%, 45% to 78%).

CONCLUSION

Food handlers professional training have been effective both in the same context and in a different context; the training should be based on both the operator's knowledge and difficulties met during the training; knowledge obtained by training is kept unchanged for some years, and it is supposed to repeat the course after one or two years; the analysis of the areas has confirmed the existence of critical problems, common causes of epidemics in collective catering services.
