Course ID: | FDST 7060E. 3 hours. |
Course Title: | Microbial Hazards in Food: Assessment and Control |
Course Description: | Common infectious agents and toxins associated with food.
Potential for these agents to enter the food supply, strategies
for control, the development of microbiological criteria,
sampling strategies, and interpretation of data will be
discussed. This course will provide microbiological background
for the development and implementation of HACCP programs. |
Oasis Title: | Microbial Hazards in Food |
Nontraditional Format: | This course will be taught 95% or more online. |
Prerequisite: | FDST 7020E or permission of department |
Semester Course Offered: | Offered spring semester every even-numbered year. |
Grading System: | A-F (Traditional) |
|
Course Objectives: | 1. Describe the uses and limitations of analytical methods used
to detect microorganisms in foods
2. Describe the biochemical basis for selective and
differential reactions used to detect and characterize
food-borne pathogens
3. Apply statistical concepts to the interpretation of
microbiological analytical data and the development of
sampling strategies
4. Understand the effects of heat, acid, and low water activity
on survival of microorganisms in foods and apply this
understanding to modified food formulation and preservation
processes
5. Describe the growth and survival characteristics of
microorganisms associated with food-borne illness
6. Analyze food processing and distribution systems to
determine practices and designs associated with foodborne
illness
7. Justify the use of microbiological indicator tests and
microbiological criteria in food purchase and product
release decisions
8. Apply microbiological testing to HACCP systems and
prerequisite programs |
