Cross-contamination
Cross-contaminationOccurs when traces of allergens get into products accidently. happens when traces of allergens get into products accidently.
This can be prevented by:
- Having separate work surfaces, chopping boards and utensils for foods prepared with or without allergens and cleaning all of them before and after use.
- Storing ingredients and prepared foods separately in closed and labelled containers.
- Keeping ingredients that contain allergens separate from other ingredients
- Washing hands thoroughly between preparing dishes with and without certain allergens.
Cross-contamination can happen through using the same cooking oil. For example, gluten-free chips can't be cooked in the same oil which has been previously used for cooking battered fish because of the flour in the batter.
If you can鈥檛 avoid cross-contamination you should tell customers that you can鈥檛 provide an allergen-free dish.
All staff involved in handling ingredients, equipment, utensils, packaging and final food products should be aware of and aim to minimise the possibilities of cross-contamination with allergens.
Very small amounts of some allergens can cause severe allergic reactions in sensitive people. It is so important to clean thoroughly in a way that reduces the risk of cross-contamination.
Some methods of cleaning may not be adequate for removing some allergens. Dismantling equipment and cleaning each individual part with water (if appropriate) by hand is a good way to make sure that 鈥榟ard-to-clean鈥 areas are free from allergen contamination.
Handling food allergens in the kitchen

- Recorded on product specification sheets (Recipe Sheets).
- Included on ingredients labels and ingredients should be kept in original or labelled containers.
- Included in recipes or explanations of the dishes provided 鈥 any changes to recipes must be written down.
- Up to date.
Staff must be trained so they know:
- Procedures and policies regarding food allergens.
- How to handle allergy information requests and be able to guarantee that allergen-free meals are served.
- How to reduce the risk of cross contamination when serving food.
- Understand the information regarding allergens shown on the menu and provide additional information to customers.
