Allergen Monitoring Hub Page Header

Allergen testing is a vital safeguarding process required for all food production, manufacturers, and any kind of hospitality or industry working in or around food consumption. By law, any presence of food allergens must be labelled on a pre-packaged food item and businesses selling loose food must also specify potential allergens. This also means that the potential for any cross-contamination must also be mentioned.

 

What is a food allergen and is it an intolerance?

It is important to remember that food intolerances are different from food allergies even though the symptoms can similarly present themselves. Food intolerances occur when the body reacts to eating and digesting a particular food. An allergic reaction is caused by the immune system reacting to a harmless substance, which is known as an allergen. 

Food allergens are substances that provoke allergic reactions when consumed in food, drink, sauces, and sometimes even just by exterior physical contact. Symptoms of a moderate to severe food allergy can vary to include respiratory difficulties, swollen or itchy mouth, lips, tongue and throat, nausea and/or vomiting, bloating, diarrhoea, and even hay fever-like symptoms such as itchy or red eyes and a runny nose. If you think you are having an allergic reaction to a food, it is important to identify the source of this reaction to avoid any short or long term effects. 

While technically, any food can be classed as an allergen if it causes an allergic reaction, there are 14 main allergens that UK food business must list under food law. As legislation requires that the presence of food allergens be clearly labelled on packaging, allergen management to eliminate and prevent cross-contamination is crucial.

The 14 allergen groups are:

  • Celery and celeriac.
  • Cereals containing gluten, wheat, rye, barley, spelt, kamut and hybrid species.
  • Crustaceans and shellfish.
  • Eggs.
  • Fish.
  • Lupin seeds and flour, which are commonly used in pasta, bread, and pastries.
  • Milk and dairy products.
  • Molluscs. 
  • Mustard and mustard seeds.
  • Peanuts
  • Nuts such as almonds, hazelnuts, walnuts, cashews, pecan nuts, pine nuts, Brazil nuts, pistachios, macadamia nuts, and peanuts.
  • Sesame seeds and oils.
  • Soybeans (edamame beans) and soya-based products including soya lecithin found in most food items.  
  • Sulphur Dioxide and sulphites (often used to preserve food).

How to ensure your organisation is safe from food allergens.

Taking the necessary precautions to manage and prevent any contamination caused by allergens is vital. Risk assessments, line management, and careful monitoring must be implemented, along with regular hygiene monitoring and allergen testing in the hospitality and manufacturing industries. 

The use of specific allergen testing allows you to target and identify specific allergenic protein residues on surfaces after cleaning has taken place. Antibody-based rapid lateral flow device (LFD) tests can be used for detection or enzyme-linked immunosorbent assay (ELISA) tests to quantify proteins present on a surface. 

Where multiple allergens are handled on-site, different methods of detection, cleaning and validation may be required, and the effectiveness of cleaning procedures must be validated and documented. Validation should be done by accredited testing methods and wherever possible quantifiable. Lateral flow tests and ATP testing can be used but are suitable for verification only.

As well as being used for environmental monitoring, many LFD allergen tests from Hygiena™ and 3M™ can be used on a raw product, liquid and solid end-product and CIP rinse water to detect allergen residue.
