Why allergen control matters
Food allergies are not a personal preference, but a global public health concern. For some, exposure to even small amounts of protein from an allergen can lead to severe – sometimes life-threatening – reactions. That is why regulators and authorities around the world have developed legislation, standards, and guidance documents to govern how allergens must be managed and declared on food products.
For food businesses, allergen control is not optional; it’s fundamental.
Why your business needs to control allergens
There are three primary reasons every food business should take allergen control seriously:
- Consumer protection – To prevent harm to consumers, and by extension, to protect your brand’s reputation.
- Regulatory compliance – To meet national and international food labelling requirements.
- Food safety compliance – To align with recognised food safety certification schemes and standards such as HACCP, BRCGS, FSSC 22000, SQF and IFS.
Allergen control is therefore both a legal and a food safety obligation, and an ethical responsibility.
Understanding food allergies, intolerances, and coeliac disease
Although these three conditions are often mentioned together, they are distinct in their causes, mechanisms and health implications.
Food allergies are abnormal immune responses to otherwise harmless food proteins – for example, peanut protein. The immune system mistakenly identifies the protein as a threat, and launches a defensive response to neutralise it.
Allergic reactions can vary widely, from skin irritation and digestive discomfort to severe systemic responses such as anaphylaxis. Most allergic reactions occur soon after consuming or even coming into contact with the allergenic food.
Food intolerances, on the other hand, do not involve the immune system. They occur when the body struggles to digest or process certain food components. Reactions are often dose-dependent – the more you consume, the stronger the reaction.
There are three main types of food intolerance:
- Enzymatic intolerances – e.g. lactose intolerance, caused by a deficiency in the enzyme lactase.
- Pharmacological intolerances – reactions to active components such as histamine, which can cause scombroid poisoning.
- Undefined intolerances – a broad group including reactions to food additives such as sulphur dioxide and certain colourants.
While intolerances are rarely life-threatening, their symptoms can mimic those of food allergies, making diagnosis and management challenging.
Coeliac disease is an autoimmune disorder, not an allergy or intolerance. It is triggered by gluten, a group of proteins found in wheat, barley, rye, and spelt, and it causes the body’s immune system to attack the small intestine. Over time, this damages the intestinal villi responsible for nutrient absorption, leading to malnutrition, diarrhoea, weight loss and fatigue. If left unmanaged, it can increase the risk of developing certain cancers.
Unlike allergies, for coeliac disease the symptoms may not appear immediately, but worsen with continued gluten exposure.
The impact on consumers
There is currently no cure for food allergies, intolerances, or coeliac disease. The only management strategy is strict avoidance of the offending food or ingredient. This means consumers and caregivers rely on accurate allergen labelling to make safe purchasing choices. If allergen information is missing, unclear or incorrect, the consequences can be serious – both for consumers and for food businesses.
The impact on food businesses
The consequences of inadequate allergen control extend far beyond consumer health. Over the past decade, undeclared allergens have consistently been one of the leading causes of product recalls worldwide. Each recall is costly, both financially and reputationally.
Beyond the immediate loss of product and revenue, there’s also the long-term damage to consumer trust and brand credibility.
Most allergen recall incidents could have been prevented through robust allergen management programmes – systems designed to identify, control and verify allergen risks throughout the production process.
How common are food allergies?
Globally, it’s estimated that 2% to 10% of people are affected by food allergies, though rates differ between countries and populations.
Children are disproportionately affected – some outgrow their allergies, but others carry them into adulthood. Meanwhile, new-onset food allergies can also develop later in life.
Although an individual can react to almost any protein-containing food, research shows that most allergic reactions are due to a common list of foods:
- Wheat
- Crustaceans
- Eggs
- Fish
- Peanuts
- Sesame
- Milk
- Certain tree nuts
In addition, many countries recognise their own priority allergens – such as soy, mustard, lupin, celery and buckwheat – based on local dietary habits and prevalence.
The bottom line
Food allergies and coeliac disease are different types of adverse food reactions, but all share a common requirement – effective allergen control. Without proper management, consumers face serious health risks, and food businesses face regulatory action, recalls and reputational harm.
Implementing a comprehensive allergen management plan is therefore not just about compliance; it’s about protecting lives and building trust.
At FACTS, we support food businesses in developing, validating and verifying allergen control strategies that are practical, science-based, and aligned with international best practice. Together, we can reduce the risk and make food safer for everyone.
