How does food become hazardous? Food becomes hazardous by contamination. Contamination is the unintended presence of harmful substances or microorganisms in food. Food can become contaminated from: Chemical hazards Physical hazards Biological hazards
  3. 3. What is “cross contamination?” Cross-contamination is the transportation of harmful substances to food by: What conditions encourage bacteria to grow? Warm Neutral-slightly acidic pH Moist Protein-rich 41°F (5°C) and 135°F (57°C)

  8. 8. F A TIMETIMET O M Foodborne microorganisms need sufficient time to grow! They are capable of doubling their population every twenty minutes. If potentially hazardous food remains in the temperature danger zone for four hours or longer, foodborne microorganisms can grow to levels high enough to make someone ill.
  9. 9. F A T T OXYGENOXYGENM While most microorganisms need oxygen to grow, some do not! Examples of foods that are associated with bacteria that do not need oxygen to grow are: o Cooked rice o Untreated garlic-and-oil mixtures o Baked potatoes
