  • Etiological factors of foodborne diseases
    The various microorganisms that cause foodborne illness and their relationship with food.
  • Introduction to epidemiology
    What is epidemiology and what is the purpose of epidemiological studies. The history of epidemiology. Terminology. The basic principles of descriptive and analytical epidemiology.
  • Epidemiology of foodborne diseases
    Analysis and comparison of epidemiological data from Greece, Europe and the rest of the world. The investigation of temporal and geographical changes in the incidence of foodborne diseases.
  • Factors affecting the incidence of foodborne illness
    Causes of real and apparent changes in incidence.

  • Microbiological food safety
    Overview of the European Union Food Safety Legislation and System. Basic scientific concepts of food safety, history and principles of food safety isk assessment, data collection and processing. Hazard identification, Hazard characterization, Exposure Assessment, Risk Assessment. Introduction to microbiological risk assessment (MRA). Identification and hazard characterization of pathogenic microorganisms in food and water. Exposure assessment and risk characterization in microbiological risk assessment. Risk management and risk communication using print and electronic media.

Educational Goals

The aim of this course is to train students in basic concepts of Epidemiology and the relationship of foodborne infections to public health. In addition, they will delve into basic scientific concepts of food safety, such as food hazard assessment through hazard identification, hazard characterization, hazard exposure assessment, and hazard probability characterization.

General Skills

The students will be familiarized with the use of mathematical models and formulae form  the prediction of the behaviour of pathogenic microorganisms under different conditions and processes.

Teaching Methods

Face to face:

  • Lectures (theory and exercises) in the classroom.

Use of ICT means

  • Lectures on PowerPoint slides using PC and projector.
  • Notes and solved exercises in electronic format.
  • Use of videos and online applications in teaching.
  • Post course material and communicate with students on the Moodle online platform.
