Learning objectives
The course aims to enable the student to independently draw conclusions regarding the microbiological analysis for determining the safety and quality of raw materials for the agri-food industry in accordance with what is defined in the specific objectives of the study course. professionalizing Quality and Supply of Raw Materials for the Agri-Food and food microbiology area.
The expected learning outcomes are:
Knowledge and understanding: Knowledge of the analytical parameters to be determined and the methods to be applied for both qualitative and quantitative microbiological analysis of a food matrix also in reference to current regulations
Application skills: apply methodologies and techniques for the microbiological analysis of foods
Making judgements: evaluating the microbiological quality of a food based on the result of a microbial count of the raw materials
Communication skills: communication of a result of a microbiological analysis of a liquid and solid food also in reference to current regulations.
Ability to learn: Ability to critically consult current regulations and regulations, databases and websites relating to microbial counting methods for specific microorganisms
Prerequisites
Full knowledge and mastery of what has been learned from teaching the Laboratory of Microbiology of raw materials and microbiological analysis techniques and Microbiological Quality and Safety of Raw Material of Animal and Plant Origin
Course unit content
The course completes the contents of Quality and Microbiological Safety of Raw Materials of Animal and Plant Origin and concerns the application of microbiological analysis techniques to verify the safety and quality of raw materials for agri-food. There are 3 CFU of exercise which include 45 hours of lessons divided between classroom and laboratory exercises.
The first part of the exercises involves the preparation of the different types of selective media and then all the specific analyzes with qualitative and quantitative determination methods with direct and indirect culture-dependent and independent methods with particular attention to spore-forming bacteria. The second part of the exercises involves the study and application of the Challenge Test to raw materials of animal and plant origin.
Attendance of the hours of laboratory exercises is mandatory, unless justified by the teaching professor. The teacher will communicate to the students, at the beginning of lessons, the maximum number of absences allowed. Attendance is verified according to methods and criteria established by the individual teacher who makes them known to the students at the beginning of the lessons.

Slides of lessons
Teaching methods
Teaching will be through frontal exercises both in the classroom and in the laboratory. The lessons will be carried out with the aid of slides which will represent teaching material, in addition to the recommended texts. The slides will be available online on the Elly SAF website in pdf format for students and some videos useful for viewing the operational sequences of the plate count analysis. During the lessons, the appropriate use of technical language will be reiterated, and the connections between the various parts of the course will be underlined. The content of the exercise lessons, carried out both in the classroom and in the laboratory, individually and in groups, will be an integral part of the final evaluation.
Assessment methods and criteria
The content of this part of the teaching is an integral part of the assessment to verify the learning assessed for "Quality and Microbiological Safety of Raw Material of Animal and Plant Origin". In particular, 2 of the 10 questions of the first part and 10 of the 31 questions of the second part included in the written test are related to this part of the teaching. The questions relate to the entire program of activities carried out in the classroom and in the laboratory
