COURSE DESCRIPTION
This course is designed to introduce students to various aspects of food microbiology, organisms
associated naturally with foods and those responsible for spoilage. Conditions favouring the
growth, death and survival of microorganisms in foods will also be studied; their immediate and
long range effects on foods will be discussed. Issues of foodborne diseases, food spoilage and
preservation will be treated. Topics to be covered include Introduction to food microbiology;
factors that affect interactions of microorganisms with foods; microorganisms important in foods:
1
bacteria, moulds, yeast, viruses, protozoa, algae - their classification and growth characteristics. Also
included are food spoilage and preservation; food-borne diseases - infections and intoxications;
public health and sanitation and microbiology of water.
COURSE OBJECTIVES
The objectives of this course are to:
 introduce students to the use of computers for various academic activities; and
 provide students with opportunities to develop basic computing skills with respect to
preparation of documents, use of spreadsheets, making PowerPoint presentations, and
efficient use of the Internet.
COURSE LEARNING OUTCOMES / COMPETENCIES
Upon successful completion of this course, students should:
(Knowledge based)





be familiar with intrinsic/extrinsic conditions affecting the growth, survival and death of
microorganisms in foods;
recognize names and taxa of important bacteria and have an understanding of their
properties (environmental, biochemical, physiological) as they pertain to spoilage, safety
and industrial importance;
be familiar with hurdle technology and other preservation techniques relative to food
safety and spoilage;
be able to distinguish between microbial foodborne intoxications and infections; and
understand the etiologic agents of microbial foodborne diseases

GENERAL INSTRUCTIONS
Attendance: It is expected that every student will be in class for lectures and also participate in
all practical exercises. Attendance records will be kept and used to determine each person’s
qualification to sit for the final examination. In case of illness or other unavoidable cause of
absence, the student must communicate as soon as possible with any of the instructors, indicating
the reason for the absence.
Academic Integrity: Violations of academic integrity, including dishonesty in assignments,
examinations, or other academic performances are prohibited. You are not allowed to make
copies of another person’s work and submit it as your own; that is plagiarism. All cases of
academic dishonesty will be reported to the University Management for appropriate sanctions in
accordance with the guidelines for handling students’ misconduct as spelt out in the Students’
Handbook.
Assignments and Group Work: Students are expected to submit assignments as scheduled.
Failure to submit an assignment as at when due will earn you zero for that assignment. Only
under extenuating circumstances, for which a student has notified any of the instructors in
advance, will late submission of assignments be permitted.
Code of Conduct in Lecture Rooms and Laboratories: Students should turn off their cell phones
during lectures. Students are prohibited from engaging in other activities (such as texting,
watching videos, etc.) during lectures. Food and drinks are not permitted in the laboratories.
