| Course abstract | |
| The study course examines the potential microbial contamination of food products and its effects on the health of the consumer. Students acquire theoretical and practical skills in determining contamination in food products and the regulation in legislation, and are able to analyze the possibilities of preventing such contamination. Master students independently analyze literature about possible contamination of a food product and propose the options to limit it. | |
| Learning outcomes and their assessment | |
| Knowledge of microbiological safety of food products and microorganisms causing their spoilage – lectures and written test
Skills to assess microbiological contamination of food products according to standard methods – lectures and lab works Competence to choose appropriate methods for analysing microbiological safety of food and competent evaluation of the obtained results – lab works and independent work |
|
| Course Content(Calendar) | |
| 1.Characterization of the types of contamination of food products. Risk analysis.
2.Regulatory enactments on food safety. Definitions and terminology. 3.Overview of the classification of micro-organisms.

|
| Requirements for awarding credit points | |
| For accumulative exam student has to particiapte in all laboratory works, successfully pass theoretical test (grade 4 or above), and defend both indipendent work presentations. | |
| Description of the organization and tasks of students’ independent work | |
| Independent analysis of literature on possible contamination of a food product – two presentations (one on plant based product and one on animal based product).
Each presentation should include the following chapters (structure of individual work): 1.Problem statement 2.Characteristics of the chosen product 3.Microflora of the chosen product 4.Factors and risks which affect microbial safety 5.Sources of microbial contamination 6.Food-borne illness and food contamination cases 7.Main possible pathogens in chosen product 8.Detailed characterisation of one pathogen (possible in chosen product) 9.Ensuring microbiological safety of chosen product 10.Mandatory safety and quality requirements 11.Detection methods of microorganism/s 12.Summary 13.References Each presentation should contain references that are given at the end of the presentation in the “References” slide. At least 60% of the literature sources (not including images or other graphs / tables) should be scientific publications in order to receive the maximum score. Volume of report - presentation of at least 14 slides (students can use a template file on Moodle: course-paper_template). |
|
| Criteria for Evaluating Learning Outcomes | |
| The examination mark is formed as the mean arithmetic of the tests results and the presentations of the independent work. The test is successfully written if at least 50% of the answers are correct. | |
