About

*** Dr. McMullen is not accepting any new staff or students as she has retired. ***

Degree

PhD, Food Microbiology, University of Alberta

Job/Research Area 

Food Microbiology


Research

Major Responsibilities/Research Interests 

Areas of interest include the use of lactic acid bacteria as biopreservatives in food systems, microbial ecology and its effects on sensory quality of foods, and detection of pathogens. Currently, the use of lactic acid bacteria and their bacteriocins as biopreservatives for controlling the growth of foodborne pathogens such as Listeria monocytogenes in packaged food is being investigated. Teaching responsibilities include food microbiology, food safety and food fermentation.

Courses

Providing students with an understanding of the principles of risk: benefit evaluations related to safety concerns about foods. Not to be taken if credit received for NU FS 427. Prerequisite: consent of instructor.


NU FS 361 - Food Microbiology

Environmental factors affecting the growth, activity and destruction of microorganisms in food and their application to control foodborne illness and spoilage in the food processing and food service industries. Not to be taken if credit received for NU FS 363. Prerequisite: MICRB 265.


NU FS 363 - Food Microbiology

Environmental factors affecting the growth, activity, and destruction of microorganisms in food and their application to control foodborne illness and spoilage in the food processing and food service industries. Not to be taken if credit received for NU FS 361. Prerequisite: BIOL 107, BIOL 108, or *3 MICRB.


NU FS 427 - Food Safety
