- ANFS 102 - Food For Thought
- ANFS 230 - Foodborne Disesases: Outbreak Investigation
This course will explore the "hows" and "whys" of foodborne outbreak investigation. This includes examining current outbreaks and real-life situations using principles of epidemiology; while highlighting the importance of all investigative roles, including the epidemiologist, public health worker, and laboratory scientist. Also, through individual and group problem solving and research, participants will examine case studies while learning to use surveillance, detection, and investigative skills to solve an outbreak. Additionally, ways in which this information should be communicated to the public will be addressed. - ANFS 315 - Food Safety from 'Farm to Fork'
This course will examine the major food production systems in animals and plants (dairy, beef, swine, poultry, and seafood). Today's modern food production systems are full of controversial issues of scientific, political, and personal importance. We will consider pathogenic bacteria, viruses, and parasites, government regulations, the use of antimicrobials in food animal production and plant production, natural hazards in food plants, pesticide residues, and organic farming to name just a few. Additionally, we will explore the consumer's perception of biotechnology and its use in food production, organic farming, and the relationship of post-harvest handling of agricultural commodities and food products to food safety.
