Why it matters

  • Food poisoning: illness caused by eating food with harmful bacteria, toxins or chemicals. Signs are vomiting, diarrhoea and stomach pain.

Safe temperatures

  • Danger zone: 5 to 63 degrees Celsius. Bacteria multiply fastest here.
  • Fridge: 5 degrees Celsius or below. Hot holding: 63 degrees Celsius or above.
  • Cook poultry to a core temperature of 75 degrees Celsius.

Good habits

  • Wash hands with soap before cooking, after the toilet and after touching raw meat.
  • Cross contamination: germs move from raw food to cooked food. Use separate boards and knives.
  • Thaw meat in the fridge, not on the counter. Reheat leftovers until piping hot.
  • Pests: flies, rats and cockroaches spread germs. Cover food and bin waste.
