Foodborne Illness • Contaminants- substances that make food unfit for use • Foodborne illness- sickness caused by eating food that contains a harmful substance • 75 million Americans per year • Children, pregnant women, elders, chronically ill are most at risk • 5,000 deaths
Foodborne illness cont… • Microorganisms- living creatures that are visible only through microscope; most cases can be traced to them • Bacteria-single cell organisms • toxins- poisons produced by bacteria that cause illness • Spores – protected cells that develop into bacteria under the right conditions (food, warmth, moisture)
Food Safety • Food safety- keeping food safe to eat by following proper food handling and cooking practices. • Keep yourself and your kitchen clean • Don’t cross-contaminate • Cook food thoroughly • Refrigerate food promptly
Personal Hygiene • Keep yourself clean to avoid transferring harmful bacteria when handling food • 20-second scrub • Tie hair back • Sneeze or cough • Clean clothing • Open wounds
Clean Kitchen • NO PETS ALLOWED! • Wash work surfaces • Wash tops of can • New taste = new spoon • Change dishtowels often
Clean up time!!!!! • Clean as you go along! • Washing dishes by hand • Scrape and rinse • Order by likeness • Glasses,flatware, plates and bowls, kitchen tools, serving pieces and containers, cookware • Keep sharp knives separate • Soak, wash, rinse • Hot water!
Cross-Contamination… • Occurs when harmful bacteria spread from one food to another • Uncooked food -> cooked food • Raw meats -> fruits and veggies • Used tools and equipment -> food
DANGER zone • 40 degrees – 140 degrees • Cook to proper internal temperature • Temperature registered at the center of the thickest part of the food • Usually 160 degrees • Taste until fully cooked • Never partially cook • Watch for cool spots in microwave • Reheat to 165 degrees
Serving Food Safely • Three magic rules • Keep hot foods hot! Aim for over 140 degrees • Keep cold foods cold! Aim for below 40 degrees • 2-hour rule...perishable foods shouldn’t sit at room temp for more than 2 hours • If temperature is over 90 degrees throw it out after 1 hour!
Thawing Food • Under running cold water • In microwave • In refrigerator
Spoiled Food Magic Rule #2 When in doubt …. Throw it out!!!!!!!!
Storing food • Buy only what you want • Follow package directions for storing item • First in … first out • Write purchase date if there is no sell or use-by date • Used canned food within a year • Clean storage areas regularly

Food that will not spill Food that will not spill Raw meats, stocks, soups, sauces, juice Fruits and veggies Fruits and veggies
Freezer Storage • Temperature at 0 degrees or lower • Fairly full freezer functions best • High water content foods don’t freeze well • Freezer burn – moisture loss caused when food is improperly packaged or stores in freezer to long • Tough, grayish brown spots • Stale taste and aroma • Ice crystals
Agencies and Administrations • FDA – Food and Drug Administration • In charge of overall safety of the food supply • GRAS list – items that are generally recognized as safe • HAACP- Hazard Analysis and Critical Control Point is designed to predict and prevent threats to food safety at various points in food processing and service. • Irradiation- process of exposing food to high intensity energy waves to increase its shelf life and kill harmful microorganisms. • Recall- immediate removal of a product from store shelves.
EPA • Environmental Protection Agency • Environmental impact of food production • Pesticides • Disposal of wastes • Protects nation’s water supply • Chemical residues
CDC • Centers for Disease Control and Prevention • Protects health and safety of people • Foodborne and waterborne diseases
