Learning objectives
The course aim is to provide the skills to assess the quality and health of food of animal origin, starting from the production process up to the level of the final consumer.
Expected learning outcomes
At the end of the course the student must be able to know the main rules governing the conformity of food of animal origin destined for human consumption and the main contaminants in the food chain of animal origin. It must also be able to control and manage the processes of production, preparation, processing, packaging and preservation of food of animal origin for the purpose of preventing and controlling the health risk associated with the various production phases.
Course syllabus and organization

Single session

Responsible
Lesson period
First semester
Prerequisites for admission
Knowledge of chemistry, biochemistry, microbiology, infectious diseases, nutrition, toxicology and physiology are required.
Assessment methods and Criteria
Oral question on all topics of the course (theoretical and practical) carried out in the year in which the student had followed the course
Evaluation parameters: ability on the part of the student to critically evaluate them and to understand their hygiene and health problems in the sector in order to implement prevention and risk assessment means, based on national and European regulatory references
In particular, the ability to report on the topics covered and to combine the theoretical part with the practical part will be assessed; ability of critical reasoning, quality of exposure and competence in the use of an appropriate language.
