October 4, 2021

Since the founding of the United Nations Food and Agriculture Organization (UNFAO) on October 16th of 1945, World Food Day has been celebrated every year and worldwide to raise awareness of global food issues. In light of 2021’s theme “Safe food now for a healthy tomorrow”, let us check out some tips advised by The Centre for Food Safety (CFS) on cooking and reheating food safely!



  • Purchase from hygiene and reliable source of food
  • Check the storage temperature and conditions before purchasing
  • Check the expiry date of the pre-packaged food before purchasing



  • Wash hands with soapy water for 20 seconds before and after food preparation
  • Wash utensils and worktops with hot water and detergent after food preparation


  • Separate raw food from other foods especially ready-to-eat items in grocery cart and bags
  • Store raw food under cooked food or ready-to-eat food in refrigerator compartments
  • Use separate knives, cutting boards, containers and tableware for raw food and other items




  • Ensure the core temperature of food reaches at least 75°C
  • Bring soup and stews to a complete boil for at least one minute
  • Check that juices of poultry and meat are clear, not red
  • Check that egg yolks are not runny
  • Reheat leftovers thoroughly before consumption and reheat once only



Safe Temperature

  • Check and keep refrigerator at 4°C or below; freezer at -18°C or below
  • If not consumed immediately, keep cooked food above 60°C
