MICR331 Food Microbiology

The fundamentals of food microbiology and its importance to the community; food preservation; food allergies; food-borne infections; the microbiological analysis of foods including data interpretation.

Food production is New Zealand's biggest commercial operation. Its success is dependent on the consistent delivery of high quality products. Consistently delivering high-quality food requires: an in-depth knowledge of the microflora associated with each product, the application of systems designed to inhibit the growth of pathogenic and food spoilage organisms, and the ability to identify unsatisfactory product. Currently in New Zealand there is a shortage of experienced food microbiologists.

Appropriate for students studying Microbiology, Food Science, Health Sciences, Human Nutrition or Public Health.

Teaching staff

Convenor: Dr Daniel Pletzer

Other Lecturers: Professor Phil Bremer and Professor Roslyn Kemp

Paper Structure
Lectures address the following issues:
  • What pathogenic microorganisms may be present in food
  • Food intolerance and food allergies
  • What technologies are available to limit the growth of microorganisms in food
  • What management options are available to keep our food supply chain safe
  • What technologies are available to detect microbes in food
These concepts are further explored in laboratory exercises.

  • A hazard and assessment (HACCP) plan presentation 15%
  • A laboratory skills test 15%
  • Final exam 70%
Teaching Arrangements
There are two lectures per week for all weeks of the first semester. There may be two laboratory sessions per week, with each laboratory session divided into two streams to create timetable flexibility for students. Students can leave labs to attend lectures if required. The laboratory classes run in weeks 9-12 of the first semester.

Textbooks are not required for this paper.
There are excellent web-based resources, and the University Science Library has an extensive collection of relevant material.
