As part of an allergy management plan, many sites use different coloured production and hygiene utensils for different types of allergens (often called 'colour coding').
By having a clearly visible difference between allergen and non-allergen, and between allergens themselves, this prevents cross-contamination when handling different ingredients. IndeliMarking has also proved a useful method for further increasing control of plastic and stainless steel items in a food-safe and hygienic way.
