Allergens are a growing concern for food producers and people suffering from allergies. European regulations state that any of the designated allergens must be declared on the food packaging if these are contained in the ingredients list.
Allergens can already have a serious impact on allergy sufferers even at very low levels, and, consequently, their unintended presence due to cross contamination is a key concern for the food industry. Allergen control in food and food production requires sound risk management systems (for both prevention and reduction) and surveillance through reliable analyzes with adequate sampling and control. For safety assessment or troubleshooting, the relative contamination in the production chain needs to be determined at several locations and time intervals.
