Food Microbiology Lab Practices

This seminar will focus on current topics in food safety and quality as related to pathogens of concern and spoilage organisms, techniques in testing, and whole-genome sequencing.  Common sources of laboratory contamination and error, as well as best practices to avoid, will be discussed throughout the seminar. Delivered in partnership with Merieux NutriSciences.


This two day course provides participants with a thorough understanding of the basic factors that influence microbial growth and survival in the food processing environment. 

  • Explore various microbiological organisms in food
  • Discover the various physical and chemical agents used to control microorganisms in food
  • Learn about food related illness from microorganisms
  • Determine microorganisms that can cause food spoilage

As this is not part of the certificate program, there is no test required.
