Learning unit contents
Lectures (including online course):
The first part of the course will be structured as follows:
- Introduction to foodborne illnesses and their importance in public health.
- Main foodborne pathogens: helminths, protozoa, bacteria, viruses, mycotoxins, marine biotoxins, biogenic amines, unconventional transmissible agents.
- Characteristics of the main bacteria responsible for foodborne illnesses: Salmonella, Yersinia, enterohaemorrhagic E. coli O157, enteropathogenic Yersinia enterocolitica, Campylobacter, Vibrio cholerae, Vibro parahaemolyticus, Vibrio vulnificus, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus, Clostridium botulinum , Listeria monocytogenes and other agents.
- Main organisms responsible for spoilage or used to transform or preserve food.
- Management of the microbiological shelf life of foods by producers including predictive microbiology.
- Principles of microbiological analysis of food: sampling plans, sampling, sample management, test sample, counts, detections, identifications, typing.Alternative methods in food microbiology, including genetic methods.
- Applications of the microbiological analysis of foods and significance of the flora detected or counted.
- Accreditation of laboratories and recognized methods.Definitions, development and use of microbiological criteria.
Practical work consisting in the counting and research of the main micro-organisms contaminating food by traditional method of culture, by immunodiagnosis and genetic method; control of water, air and surfaces.
Organization of a food microbiology and biosafety laboratory.
Tutorials:
Tutorials consisting of exercises in predictive microbiology and the setting of microbiological criteria and the interpretation of the results of microbiological analyzes in relation to the criteria in place.
Learning outcomes of the learning unit
At the end of the first part of this teaching given mainly online, the student will have to know the main characteristics of biological agents in food: taxonomy, physiology, virulence, reservoirs, sources of contamination, associated foods, control measures. He must also be able to propose solutions to fight against pathogenic and spoilage agents and to promote the flora sought in the main categories of foodstuffs.
At the end of the second part of this course and the practical exercises associated with it, the student should be able to understand the techniques implemented by food microbiology laboratories and to choose the methods best suited to each situation. He will be able to choose the optimal flora to be counted or searched for according to the objectives set and to interpret the results obtained according to microbiological criteria.
Prerequisite knowledge and skills
Basic knowledge in microbiology required for a proper understanding of education.
Planned learning activities and teaching methods
This Teaching Unit essentially aims to acquire knowledge through traditional face-to-face or distance learning integrating formative assessments. The practical application of the concepts taught via practical work in the laboratory and exercises carried out during the tutorials will allow you to consolidate the knowledge acquired.
Mode of delivery (face to face, distance learning, hybrid learning)
Blended learning
Further information:
Blended learning
Additional information:
This is a hybrid course based on a set of online media (MOOC, Podcasts, reference sheets) which will serve as the basis for face-to-face lessons and for carrying out the exercises.
16 hours of lectures, 16 h of eLearming, 16 h of practicals and 8 hours of tutorials
Course materials and recommended or required readings
Platform(s) used for course materials:
- eCampus
Further information:
All teaching materials will be accessible via eCampus from the beginning of the academic year. They will be of various types (MOOCs, Podcasts, Powerpoint materials, reference documents available on eCampus or via links on the Web).
The ANSES summary sheets covering the main risks of biological origin transmitted by Food (https://www.anses.fr/fr/content/fiches-de-dangers-biologiques-transmissibles-par-les-aliments) are the main knowledge bases for this subject.
