A guide to General Allergen Monitoring

What is a food allergy?

A food allergy is a medical condition in which exposure to food triggers a harmful immune response. This immune response, or allergic reaction, occurs because the immune system attacks proteins in the food that are normally harmless. The proteins that trigger the reaction are called allergens.

In the UK it is the law for food businesses to inform consumers if they use any of the following 14 key allergens as ingredients in the food and drink they provide:

  • celery
  • cereals containing gluten – including wheat, rye, barley and oats
  • crustaceans – such as prawns, crabs and lobsters
  • eggs
  • fish
  • lupin
  • milk
  • molluscs – such as mussels and oysters
  • mustard
  • tree nuts – including almonds, hazelnuts, walnuts, brazil nuts, cashews, pecans, pistachios and macadamia nuts
  • peanuts
  • sesame seeds
  • soybeans
  • sulphur dioxide and sulphites (if they are at a concentration of more than ten parts per million)


Allergens in Production facilities

Your production area should be designed to separate specific products. If this isn’t an option, you could schedule food production in order from least allergenic to most allergenic. This would be an effective method to manage cross-contamination.
In terms of storage, your facility should store raw ingredients containing food allergens away from the rest of the ingredients. Store them in sealed containers with a clear colour coded label.


Allergens in Kitchens

All allergen ingredients should be recorded on product specification sheets, included in recipes and everything should be kept in original packaging or labelled packaging. All ingredients should be kept up to date.
All kitchen staff should be aware of the risks and consequences of allergen cross-contamination. They should know the procedures put in place for example:

  • Prepared foods free from one or more allergens should have separate work surfaces
  • Storing all ingredients and prepared food in sealed labelled containers
  • Staff must wash their hands thoroughly before and after preparing foods with/without certain allergens
  • Utensils must be cleaned before every use (especially if they were used to prepared food containing allergies)

If allergen contamination is unavoidable, your customers must be informed at the start that you cannot provide them with an allergen-free dish e.g. before they order at a restaurant.

Allergens in non-packaged food

Food served at a restaurant or a takeaway should have allergen information available in written form before placing the order and receiving it e.g on a menu or website.
Foods sold loose in retail outlets, e.g. cheeses from a delicatessen and bread in a bakery should have personnel there for customers to ask ingredient information.

Allergens in packaged food

Any food packaged before it’s placed on sale must have an ingredients list. Packaged food which is:

  • Ready for sale
  • Either fully or partly enclosed by packaging
  • Can’t be altered unless the packaging is opened

Food made and packaged at the same premises for direct sales, such as pies and sandwiches, are expected to have personnel there for customers to speak to. Allowing them to ask any questions about ingredients.


Cleaning surfaces of allergens

Cleaning is extremely important when it comes to reducing the risk of cross-contamination. Something cleaning methods may prove ineffective for removing some allergens. Taking equipment apart and giving everything a good clean is a great way to ensure ‘hard-to-clean’ areas are allergen-free. Following and developing your cleaning regime will help you and your team keep on top of the risk of contamination. Ensure the surface is clean with an allergen swab. Across the UK, more food and drink businesses are looking for reliable products to show due diligence in preventing cross-contamination in production facilities and preparation areas. Gem Scientific supply a range of allergen-specific tests in both rapid lateral flow and ELISA formats. Our team of experts are on hand to provide guidance, training and support in relation to ATP, hygiene monitoring and management systems.

Training staff

Ensure all staff (including temporary staff and contractors) are aware of food allergens and the repercussions of their ingestion by sensitive individuals. Especially if they’re handling ingredients, equipment, packaging, and final food products.
They should all be trained to avoid cross-contamination of foods. As everyone has different tolerances, it is important food companies have a qualitative approach to allergen management and risk assessment.
