Food Born Illness YOU could be next!!
What is food born illness? • Illness resulting from eating food contaminated w/ a bacteria or virus. • May cause outbreaks where many people become sick, with the same illness at the same time. (about 10% of a population) 1. Usually contaminated food comes from a location away from home (restaurant, baseball game etc.).
Epidemiology • The tracking of outbreaks of illness (not always food illness) to discover where the original source of contamination came from. • Why? • To PREVENT it from happening again!
Bacteria 1. Many types live in poultry & swine (birds & pigs) 2. Can be found in environment a. water b. soil c. insects d. animal feces 3. Found in undercooked meats, eggs a. 1 in every 3 eggs is contaminated! b. Illness can be avoided if eggs are cooked properly. Salmonella
3 Conditions BAC need to live • Warmth • Moisture • Nutrients
2 factors that kill BAC! • Extreme heat(this is BEST!) • Extreme cold Pasteurization - a heat treatment used to kill bacteria. (commonly used with milk & juice)
Symptoms • Nausea • Vomiting • Stomach cramps • Diarrhea • Fever • Headache • CAN be fatal - RARE!
After Ingestion of bacteria • Will be sick within 6-72 hours after eating contaminated food. (NOT usually sick immediately after eating!) • Symptoms usually last 4-7 days • Most recover without antibiotics • Diarrhea can be severe enough to hospitalize person (dehydration)
Bacteria that produces a powerful toxin & can cause severe illness. 1. Most strains harmless 2. Live in intestines of healthy humans & animals. 3. Found in undercooked ground beef & non-pasteurized milk. A. Meat can become contaminated during cattle slaughter. B. Bacteria on cow’s udders or on equipment can get into milk. E. coli
Cross Contamination - moving bacteria from one source to another. Vector - responsible party (object, machine) that actually carries the bacteria from source to source. Host - original source of contamination. IMPORTANT vocabulary!
All the same symptoms as Salmonella. PLUS you CAN have….bloody diarrhea! In children under 5 years old & in the elderly it can cause kidney failure, & destroy red blood cells - RARE, only 2-7% of cases. Symptoms
After Ingestion of E.coli • Illness usually lasts 5-10 days • Most people recover w/out antibiotics • Should NOT use anti-diarrhea medications. WHY? - keeps BAC in body & allows BAC to grow in warm, moist, conditions (& the BAC has lots of nutrients!) so it GROWS!
Cook all meat well a. Use meat thermometer b. Thickest part of meat should be - - 160° - beef - 170° - poultry c. If you don’t have a meat thermometer, cut into center of meat & make sure it is NOT pink! 2. Keep raw meats separate from ready-to-eat foods (salads, breads etc.) Wash hands, counter & utensils with hot, soapy water after touching raw meat. Never place cooked meat on the same plate that held raw meat. Prevention
Drink only pasteurized milk and juice. - Products that have been pasteurized… a. Will say “pasteurized” on the label b. May be sold at room temperature Wash fruits & vegetables well (dry with paper towel). Wash hands after using restroom or changing diapers to reduce risk of spreading infection. Prevention (continued)
