PART
II
Texts/References:
No text. As required, handouts of pertinent information and
research articles will be distributed as reading assignments.
Lecture notes will be distributed as Powepoint slide handouts.
Focus: Principles and issues of food safety
particularly as they relate to the perception and relative
risk of chemicals in food as causes of human cancer.
Learning
Objectives
• Understand food safety issues, and appreciate the
difference between perception and reality, risk and benefit
• Know how to define terms related to food safety
• Understand complexities of assessment and interpretation
of food safety risk
• Demonstrate knowledge of areas of concern with respect
to food toxicology
• Become knowledgeable concerning the relative risks
of many natural and synthetic food constituents and outcomes
related to food processing
