Food Safety & Foodborne Illness

 Keeping Food Safe Chapter 2 What is a Foodborne Illness? Foodborne illnesses are caused by agents that enter the body through the ingestion of food.  Two or more people get the same illness after eating the same food  No long-term health threat to average person  Reaction may occur in a few hours or up to several days after exposure Symptoms  Abdominal cramps, headache, vomiting, diarrhea (may be bloody), fever, death High Risk Populations Affected  Those that have a higher risk of getting a foodborne illness:  Immune system is the body’s defense system against foodborne illnesses  Elderly people  Infants and pre-school aged children  Pregnant women  People with cancer or on chemotherapy  People with HIV/AIDS  Transplant recipients What is the Cost of Foodborne Illness?  Loss of customers and sales  Negative media exposure  Lawsuits and legal fees  Increase insurance premiums  Loss of reputation  Lowered employee moral  Employee absenteeism  Staff retraining What is the Impact of Foodborne Illness?
