Abstract This study aimed to assess the food safety criteria of services used to preparation, cooking, holding and serving meals for (the female students, department) in the Cairo University Dormitory Restaurant and to adopt hazard analysis and critical control point (HACCP) system during the period of 2017-2019 in order to assure a secure supply of food for colleges students. A total of 1950 random food and swab samples throughout production chain then analyzed and monitored hazards microbiologically , chemically and physically. The HACCP system in this study implemented throughout roasted chicken (n=240), fried rice (n=240), cooked potatoes (n=240), peas (n=180), pickles (n=180) and food additives(n=300) entire production chain. Swabs of work surfaces conduct (n=480), and the handlers hands (n=90) in catering services within the university dormitory meals to assure a secure supply of food for college students. The hygienic practices assessed during the handling of raw food and cooking equipment on-site observations were done .Evaluating food’ handlers knowledge, attitude and their practices .Food safety training program were developed for improving safe food handling practices The results obtained appeared no contamination with L. monocytogenes, Salmonella spp., Shigella spp., and Clostridium perfringens before the applying of the HACCP system. While the fluctuation within the microbial numerous total viable bacteria, total molds, and yeasts, B. cereus, Staph. aureus, spore-formers, and coliforms in served meals ascribed to inadequate handling or processing procedures, multiplication of microorganisms during some production steps of meals, poor hygiene of utensils, and equipment as well as the survival of microorganisms to the cooking process. The examined food samples in boiling, roasting, frying and cooking steps were free from any detectable levels of microorganisms before and after HACCP application. All the products showed a high level of microbial load before applying the HACCP system were to undetectable count or decreased in number considerably after application of HACCP system. Application of the HACCP framework shows a low rate of examined microorganism with a decreasing percentage reached 100% of 1 or more microbial groups in serving step and p<0.05 which demonstrates a critical impact of HACCP application. Swabs samples analysis which taken before and after HACCP application from handlers, utensils, equipment and work surfaces observed different levels of significance in the reduction of microbial load in one or more of selected examination. A significant improvement was demonstrated for knowledge about personal hygiene and related to rules for preparing safe food after the training food safety program.
