What is FOOD SAFETY?Preventing foodborne illnesses
aka FOOD POISONING
Why do foods spoil?Enzymes– chemicals within foods that help
them changeMicro-organisms – bacteria, yeast, mould, Oxidation– exposure of food to oxygen
Refrigeration Keep it Safe, Refrigerate!Refrigerate foods you’ll use quickly. Freeze
raw meat, poultry or fish you won’t use in a couple of days
Why? Safe fridge temps of 4º C or below prevent
most bacteria that cause illness from growing. Freezer temps of 0º C STOP bacteria!!!
Thawing FoodDon’t thaw food on the counter!Thaw in the fridge or microwaveWhy?Thawing starts from the outside
in, so bacteria can multiply to disease-causing levels before food has a chance to thaw!!!
Washing Your HandsWash hands before preparing foodWash hands & utensils again after contact with
raw meat and poultryWhy?Hands carry tons of bacteria!Raw meat & poultry may carry bacteriaNever rinse a chicken/turkey in a sink without
disinfecting it after!!!
Wash your hands before and after handling meat and seafood; after going to the washroom, blowing your nose, coughing, and sneezing
Use soap and warm water for 20 seconds
Cooking TemperaturesCook raw meat & fish to a temp of 160ºF &
chicken to 180ºF Always pierce the thighJuices should run clear on chickenFish should flakeUse a meat thermometerWhy?Hot cooking weakens bacteria found in raw foodsContinued heat destroys bacterial cell
membranes, destroying cell protein and causing cell death
KEEP FOODS OUT OF THE DANGER ZONE!
The Danger Zone
Dealing With LeftoversPromptly refrigerate or freeze leftoversUse small shallow containers for quick
coolingWhy?Dividing food into small containers promotes
even cooling
Leaving Food Out on the CounterNever leave perishable food out more than 2
hours!!!Dangerous foods include: Milk & milk products Shellfish Dressings Processed meats Gravies Puddings & whipped cream Cooked meat & salads made from them
Why?With moisture and bacteria can double in number every 20
mins’Bacteria do not reach dangerous levels in less than 2 hours
Keeping food cold slows the growth of bacteriaPerishables – Foods that will spoil (refrigerate)Buy them last at the grocery store
