Main themes
The following themes will be addressed, in an integrated way:
- Starting from the diversity of the microbial world, development of the notions of commensal, opportunistic and pathogenic micro-organisms (virus, bacteria and fungi) associated with food matrices. Study of the genesis of microbial contaminations in foodstuffs.
- Description and illustration of physicochemical parameters associated with the survival, development or elimination of micro-organisms (and their toxins) in foodstuffs.
- Description of the main entero-pathogenic bacteria in human and the molecular and microbiological methods implemented for their detection, characterization and discrimination.
- Strategy to implement for the prevention of microbial contaminations and intoxications, to limit their development and, when necessary, to counteract their effects.

Specific formulation of L.O. for this activity, in the program At the end of this activity, the student is able to: 1. Identify, describe and distinguish bacterial and viral pathogens and opportunists, as well as protozoa and helminths involved in food toxi-infections. 2. Identify, describe and distinguish bacterial involved in food spoilage. 3. Recognise, on the basis of symptoms and syndromes displayed by sick or affected persons, the pathogens potentially involved in food toxi-infections. 4. Recognise, on phenotypic bases, micro-organisms potentially involved in the alteration and spoilage of foodstuffs or the modification and degradation of the organoleptic quality of food matrices. 5. Determine and recommend the conventional and/or molecular methods to be implemented in the detection and discrimination of pathogenic, opportunistic and spoilage micro-organisms in food matrices. 6. Choose, argue and justify the use of normalized reference methods (ISO) to be used in the protocols for the detection of pathogenic and opportunistic micro-organisms. 7. Recommend the most appropriate physicochemical and/or biochemical methods to control/prevent pathogenic, opportunistic or spoilage micro-organisms in food matrices. 8. Display a strict confidentiality, a complete impartiality and a total independence in the treatment of analytical data and client/customer reports. |

Teaching methods
- Main activity given as ex cathedra courses, which includes many practical examples and case studies.
- Participation of invited speakers (scientific colleagues and/or colleagues from the agro-food sector).
- Practical work (mandatory activity):
> Groups of 2 to 3 students,
> Case study under the supervision of an assistant/technician team,
> Directed team work on a computer,
> Writing of brief reports.
- Excursions and guided visits in Agro-Food enterprises and/or routine laboratories for microbiological analyses.

Evaluation methods
- Written exam with four parts, evaluated on a total of 17 points:
> Resolution of a foodborne problem and/or a case analysis,
> A theoretical development of a specific section of the course,
> A section in the form of a multiple choice question (MCQ),
> A series of definitions/concepts calling for short answers.
- Evaluation of the reports of the practical work performed by the student, on a total of 3 points.
