Cross contaminationWhen food that is gluten-free comes into contact with food that has gluten in it, and so is no longer gluten-free. can occur in storage, preparation and serving. Here are some tips to help prevent the problem occurring:
- gluten-freeWhen a food has less than 20 parts per million (ppm) of gluten so it is safe for people with coeliac disease to eat. foods must never be prepared on a wheat-floured surface or in a floury atmosphere
- wash down surfaces before preparing glutenA protein that is found in the cereals wheat, barley and rye. -free food
- wash hands before handling gluten-free food (especially after other food preparation)
- use separate utensils, for example, a separate toaster for gluten-free bread; separate bread boards; separate containers for butter, margarine, chutney, pickle, jam etc, as knives can transfer crumbs from regular bread
- cook and serve gluten-free foods in separate dishes
- do not deep-fry gluten-free foods in oil which has been used for foods that contain gluten such as batters or breadcrumb coatings.
