We've put together some general advice on food safety.

Cross Contamination

Updated: Aug 19, 2019

Cross-contamination is when bacteria spread between food, surfaces or equipment. It is most likely to happen when

  • raw food touches (or drips onto) other food

  • raw food touches (or drips onto) equipment or surfaces

  • people touch raw food with their hands

By avoiding cross-contamination, you can stop bacteria spreading.

What you need to do

  • keep raw and ready-to-eat foods separate

  • clean surfaces and equipment thoroughly before you start to prepare food and after they have been used with raw food

  • wash your hands thoroughly after touching raw food

How to check

  • supervise cleaning and food handling

  • check that raw and ready-to-eat foods are kept apart when they are stored, prepared and displayed

  • make sure that your staff know how to avoid cross-contamination

Easy ways to prevent cross-contamination include:

  • Use different chopping boards and different knives for raw and ready-to-eat food. Try using one colour for chopping boards and knives used with raw food and another colour for those used with ready-to-eat food.

  • Regular hand washing

  • Storing food correctly

  • Use disposable cloths and change aprons when preparing raw food especially meat
