Learning outcome

The course is relevant for everyone working with food production, quality assurance or inspection. Implementation of appropriate hygienic measures is imperative for the prevention of foodborne diseases as well as losses due to microbial spoilage or pests. The course provides an understanding of the scientific aspects of food hygiene from processing to the consumer and enables the student to evaluate and design hygienic measures in food and food ingredient productions.

Upon completion the student should be able to:

- Define the elements in Good Hygiene Practise/pre-requisite programmes
- Give an overview of the role of hygiene in food safety and spoilage
- Describe the contamination routes of major hazards
- Describe the scientific principles in cleaning and disinfection
- Describe the principles in hygienic factory layout and equipment design
- Provide an overview of major water safety issues and personal hygiene issues
- Describe major pests and intervention strategies related to food hygiene
- Describe methods to monitor hygienic measures

- Evaluate food process hygiene with focus at the post-harvest and post-farm level and identify major flaws
- Design and implement appropriate hygienic measures in the food, food ingredient and related industries

- Take responsibility for basic food hygiene programmes from the processing steps to the consumer
- Discuss and communicate hygienic problems and interventions orally and in written form


Lectures, theoretical and experimental practicals, seminars. The lectures will encompass the theoretical background, introduce problems and present cases. The students will through the theoretical exercises and the interaction during lectures and seminars, work with different aspects of hygiene.

See Absalon for specific course literature.

The students are expected to have basic knowledge in food microbiology, food technology, and food chemistry.
