OVERVIEW

The module studies the principles to ensure food safety for the protection of public health. Central themes are both the prevention of microbiological and chemical contamination in the phases of production, transformation, distribution of food and in food preparations for community use. The course also deals with aspects related to official controls, according to the provisions of food legislation, carried out to protect public health.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide students with the acquisition of knowledge about the characteristics of food in terms of hygiene and health. In particular, food-borne diseases, epidemiological surveillance methods and the study of food-borne outbreaks will be dealt with. Knowledge will be provided on the methodologies of health risk analysis and assessment during food production, distribution and in food preparations for collective use. The main methodologies for the prevention of microbiological and chemical contamination and food preservation techniques will be explained.

AIMS AND LEARNING OUTCOMES

Attendance and active participation in the proposed training activities and individual study will allow the student to:

  • - learn the principles of food safety
  • - know and understand the methods for epidemiological surveillance related to foodborne epidemics
  • - achieve knowledge of the main food-borne diseases of relevant impact in Italy and internationally
  • - know the principles of food legislation aimed at guaranteeing the safety of products and the health of the consumer;
  • Learn the principles of development and application of control systems (HACCP and official controls), to guarantee hygiene and safety of food products along the production and distribution chain

TEACHING METHODS

The module consists of lectures carried out by teachers in presence

Please refer to the AulaWeb specific teaching request for any updates due to changes in the health and epidemiological situation.

EXAMS

EXAM DESCRIPTION

The exam is composed by a written (Multiple Choice Question test) and an oral assessment (power point presentation);

Please refer to the AulaWeb specific teaching request for any updates due to changes in the health and epidemiological situation.

The final mark is given by the arithmetic average between the scores of the two assesments. The oral examination can be sustained both in the same session as the practical test or in subsequent sessions published on the UNIGE website.

ASSESSMENT METHODS

The written exam will verify the actual acquisition of basic knowledge; the oral examination will mainly focus on the topics covered during the frontal lessons and will aim to assess not only whether the student has reached an adequate level of knowledge, but also the ability to analyze and deepen the topics and quality of exposition.

Details on preparation of the exam will be given during the lessons and described in aulaweb.
