Pregnant bellyListeriosis is a food bourne infection resulting from the consumption of contaminated food.

Certain groups of the population are considered to be of greater risk of listeriosis.

  • Pregnant women & their unborn baby
  • Those who are unwell and/or have compromised immune function e.g. long term illnesses

Food safety can reduce the risk of developing serious illness as a consequence of infection with Listeria. Even foods kept cool in the fridge may contain Listeria, any foods kept longer than 2 days increase the risk dramatically.

Remember your summer food safety checks:

  • Keep cooked food separate from any ready to eat foods to prevent cross contamination and ensure freshly cooked foods are eaten as soon as possible after cooking
  • When reheating cooked food, ensure it is ‘piping’ hot and ensure that microwave foods are heated evenly through
  • Wash raw fruits and vegetables carefully
  • Wash hands, utensils and chopping boards properly to avoid cross contamination

If at risk, keep an eye out for and avoid…

  • Uncooked, smoked or pre-cooked fish or seafood products that are chilled or frozen. Reheated foods are fine if piping hot and eaten whilst hot
  • Pate
  • Cold pre-cooked chicken
  • Ham and other pre-cooked meat products
  • Stored salads and coleslaw
  • Unpasteurised milk
  • Surface ripened soft cheeses e.g. brie, camembert
