Genetically Modified Foods • What are genetically modified foods? • “crop plants created for human or animal consumption using the latest molecular biology techniques.” (Whitman, 2000) • Used since late 1980’s • Rapidly expanding around the world. • Most common crops in the U.S. • Soybean, corn, cotton, canola
GMO Benefits • Enhanced plant growth • Decreased pesticide and fertilizer use • Increased nutrient potential • Increased crop yields
GMO Risks • Emerging allergens • Herbicide-resistant weeds / “superbugs” • Ethical / moral concerns • Decreased biodiversity
GMO Regulation & Labeling • U.S. FDA “currently requires labeling of GE foods if the food has a significantly different nutritional property; if a new food includes an allergen that consumers would not expect to be present; or if a food contains a toxicant beyond acceptable limits.” (Byrne, 2007) • FDA proposed voluntary guidelines for labels in 2001
Mandatory labeling? • Pros • Consumer rights • Identification of food issues • Americans support mandatory labels • At least 22 other countries require labels • Ethical concerns • Cons • Label may imply warning • Increase costs to consumers • GE-Free food already an option for consumers • Difficult to separate
Food Safety • What is food safety? • Prevention of foodborne illnesses • Protection of food supply • Safe handling
Foodborne Illnesses • “caused by consuming contaminated foods or beverages” (CDC, 2005) • There are over 250 different foodborne illnesses • Bacteria, viruses, parasites • Difficult to diagnosis • Vague symptoms
Common foodborne illnesses • Campylobacter (cdc.gov) • Salmonella • Science.nasa.gov • E. coli (foodpoisonjournal.com) • Calicivirus • http://nabc.ksu.edu/images/uploads/norovirus.jpg
Foodborne illnesses • Signs & Symptoms • Fever, vomiting, diarrhea • Diagnosis • Treatment • Fluids • May need to see your doctor
Foodborne Illness Outbreaks • How are outbreaks detected and tracked? • Illnesses happen in a group of people • Reports go to health department • CDC starts investigation • Outbreak ends • Contaminated food is gone, food product is recalled, restaurant is closed or food processing plant is closed • http://www.fda.gov/Safety/Recalls/default.htm
