Each year, Australia records an estimated 4.67 million cases of food poisoning. Adhering to food safety guidelines is crucial to minimize the risk of food-related illness, particularly with leftovers during warmer months.

Key Food Safety Guidelines

Temperature Control

  • Ensure foods are heated to correct temperatures to eliminate harmful bacteria. Poultry and meats should reach at least 75°C.
  • Hot foods served buffet-style should be maintained above 60°C.
  • Utilize a meat thermometer to confirm adequate cooking of protein-rich foods.

Reheating Practices

  • Cooked meat should ideally be reheated only once, reaching 75°C.
  • Refrigerate cooked poultry within two hours to prevent bacterial growth. Bacteria commonly multiply rapidly between 4°C and 60°C.

The "Five-Second Rule" Myth

  • There is no scientific basis for the "five-second rule". Food that falls on the floor should be discarded.

Handwashing Importance

  • Thorough handwashing with soap and water for several minutes is the most effective method to reduce germ transmission, especially before meals.

Preventing Cross-Contamination

  • Store fresh foods, such as salads and seafood, in sealed containers and at appropriate temperatures.
  • Use separate knives and chopping boards for raw and fresh foods. Wash boards immediately after use with hot water and detergent.

Safe Defrosting Methods

  • Defrost food in the refrigerator within a container to prevent drips and contamination.
  • If using a microwave for defrosting, cook the food immediately afterward. Do not refreeze it unless it has been fully cooked.

"Grazing-Style" Food Safety

  • Perishable items like raw eggs, cheese, processed meats, and seafood should not be left unrefrigerated for extended periods.
  • Serve smaller portions on platters and replenish as needed to limit the time food sits out.
  • Discard any fresh foods left out for more than two hours.

Leftover Duration

  • Consume most leftovers within three to four days.
  • Fresh items such as meat, seafood, and eggs should be consumed within one to two days.
  • Discard any leftovers that exhibit an off odor.

Foods to Avoid Keeping as Leftovers

  • Avoid reheating raw eggs and uncooked seafood.
  • Rice and potatoes pose a higher risk of microorganism development if left at room temperature.
  • Reheating vegetables like beetroot and leafy greens (e.g., spinach) can lead to the formation of potentially harmful chemicals due to their natural nitrate content; these are best consumed fresh.
