HYGIENIC CONTROL TECHNOLOGY AND HEALTH FOOD (MOD. 2)
Learning outcomes of the course unit
The course aims to provide students with a scientific approach to the problems of hygiene in food, with particular reference to microbial and parasitic contamination of foods of animal origin as well as skills relating to the application of rules of hygiene as a preventive measure in the context of HACCP (I and II descriptor of Dublin). They also include concepts for prevention during production, marketing and storage of food for food poisoning and parasites. The technologies of food production and related legislation (national and European) are treated with the aim of providing the student with the skills needed to draw up HACCP plans as part of food production (III, IV and V of Dublin descriptor). During the laboratory exercises will be explored methods for the official tests for the detection of microorganisms is particularly important for the hygiene and safety of food products.
