  1. CPT Joseph Hout, Assistant Professor,MSPH, REHS Winter, 2008 FOOD PROTECTION

  2. Learning Objectives • Be familiar with definitions used in class • Know various foodborne allergens, bacteria, viruses, parasites, and toxins as well as the illnesses they are associated with • Know the difference between foodborne infection and intoxication • Know how to conduct a foodborne illness investigation • Be familiar with the HACCP process • Know the employee health, work practice, structural, food procurement/storage, and food preparation controls discussed in the 2005 FDA Food Code

  3. Definitions • Critical Control Point – point or procedure in a food system where loss of control may result in a health risk • Food – raw, cooked or processed edible substance, ice, beverage, or ingredient used for human consumption including CHEWING GUM • Food Establishment – operation that stores, preps, packs, serves, vends or otherwise provides food for HUMAN consumption (restaurant, market, vending location, caterer, etc) which gives food directly to consumer or indirectly through a delivery service (includes home delivery of groceries) • Includes trans vehicle and central prep facility that supplies a vending location UNLESS the vending or feeding location is permitted • Includes mobile, stationary, temp, and perm facilities regardless of where food is consumed and regardless of cost of food

  4. Definitions • Not a Food Establishment • Offers only prepacked foods that are not potentially hazardous • Offers whole, uncut fruits and vegetables • Food processing plant • Kitchen in private home • Cannot provide potentially hazardous foods to consumers • Can provide non pot hazardous foods at functions if allowed by law • Sign stating prepared in a non regulated/inspected home kitchen • Location above goods are sold is not a food establishment • Kitchen in private home functioning as a daycare • Private home that receives catered or home delivered food

  5. Definitions • Major Food Allergens • Milk • Eggs • Fish • Bass • Flounder • Cod • Shellfish • Crab • Lobster • Shrimp • Tree nuts • Almonds • Pecans • Walnuts • Peanuts • Soybeans • Wheat • Ingredients that contain • protein from any of these

  6. Definitions • Potentially hazardous food – Food that requires time/temperature control for safety (TCS) to limit pathogenic microorganism growth or toxic formation • Ratite – flightless bird such as an emu, ostrich, or rhea • Spoilage – Damage to organoleptic (smell, see, touch taste) qualities of food • Sanitary – Free of HARMFUL levels of disease causing organisms • TCS – Time/temperature control for safety – is equivalent to PHF • Unsanitary – Contains HARMFUL levels of disease causing organisms

  7. Potentially Hazardous Foods • Food that requires time/temperature control for safety (TCS) to limit pathogenic microorganism growth or toxic formation • Includes: • Raw or treated animal food • Heat treated plant food • Raw seed sprouts • Cut melons • Cut tomatoes or mixtures* • Excludes: • Air cooled hard boiled egg with intact shell • Pasteurized intact raw shell egg • Food in unopened hermetically sealed container • Product assessment showing pathogens don’t grow • Are excluded due to Aw or pH or interaction of both*

  12. Foodborne Health Hazards • Bacteria • Thermophilic (optimal growth ~50-70 C) • Mesophilic (optimal growth ~37 C) • Psychrotrophs (optimal growth ~ 15 C) • Viruses • Most heat resistant • Do not multiply in food • Parasites • Helminths (Nematode) • Protozoa • Toxins • Bacteria produced • Fungi produced • Naturally occurring

  13. Food Borne Illnesses • Infection: • Live bacterial cells are ingested • Cells grow in the digestive tract and cause symptoms – Slower onset • Intoxication: • Food that contains a toxin produced by bacteria – Not produced in the body • Toxin causes symptoms – Fast onset • Toxin Mediated Infection: • Live bacterial cells are ingested which then produce toxins in the body • Toxin causes symptoms - Mid onset
