Co-requisites:

Modules excluded:

Current from:

2004

Aims:
(i) To provide basic information on the roles of microorganisms in food spoilage and food-borne diseases and their significance to the food industry and society.
(ii) To provide information on the nature of microbiological quality assurance in the food industry and to give training on the application of the Hazard Analysis Critical Control Points system
(iii) To give practical experience of working with microorganisms in the laboratory

Assessable learning outcomes:
At successful completion of the module the student should be able to:
1. describe the basic properties of bacteria, yeasts and moulds
2. identify an organism as a bacterium, yeast or mould in the laboratory
3. select appropriate method(s) for assessing the microbial flora of foods
4 evaluate the results of microbiological tests in relation to the nature of the food and its previous history
5. describe the effects of environmental conditions on microbial growth and food spoilage and their use in food preservation
6. describe measures for the control of food poisoning bacteria
7. be able to use recognised methodologies for identifying the major food poisoning bacteria
8. describe the principles of microbiological QA and methods used to control the microbiological safety and quality of foods
9. be able to apply the HACCP system to ensure the safety of processed foods

Additional outcomes:
Develop skills in: making accurate observations; recording accurately what was done; interpreting observations and data; communicating orally and in writing; working in a team.
