Understanding & Preventing Allergen Contamination In Food Manufacturing

Welcome! Today, we’re exploring allergen contamination in food manufacturing. Let’s explore what it is, why it matters, and how it affects us!

Allergen contamination in food manufacturing is a critical issue for food safety. Even the slightest trace of an allergen can provoke severe reactions in individuals with allergies, ranging from mild symptoms like rashes to life-threatening conditions such as anaphylaxis. Managing allergens in food production is essential for safeguarding consumer health and protecting a brand’s reputation.

Allergen contamination typically occurs when ingredients like nuts, dairy, shellfish, or gluten inadvertently enter products that should not contain them. This contamination can happen at any stage of production. Common causes include:

• Shared Equipment: Many facilities use the same equipment to process multiple products. If cleaning procedures aren’t thorough, allergen residue from one batch can contaminate another. It is vital to have cleaning validation in place to ensure allergens are wholly removed between runs.

• Storage and Handling: Improper storage of ingredients can result in cross-contamination. For example, allergenic powders like flour can spill, potentially contaminating non-allergenic products. Proper segregation of allergenic ingredients is essential to prevent this.

• Packaging and Labelling Errors: Mislabelling or failure to list allergens correctly is a significant cause of product recalls. Incorrect labels expose consumers to allergens they may not know, which can cause serious health risks. This can lead to costly recalls and harm to a company’s reputation.

• Cross-contact During Processing: Allergen particles can transfer between products via air, conveyor belts, or workers’ hands. Without strict hygiene protocols, cross-contact can occur, which poses serious risks to consumers with allergies. Manufacturers use best practices, technology, and strict oversight to prevent allergen contamination. Key strategies include:

• Allergen Segregation and Dedicated Equipment: Using separate equipment for allergenic products and scheduling allergenic items to be processed last helps minimise cross-contamination risks.

• Comprehensive Cleaning and Sanitation: Facilities must have validated cleaning procedures in place. These procedures involve using the correct chemicals and temperatures to ensure allergens are completely removed from equipment and surfaces.

• Air Filtration and Ventilation: In facilities dealing with powdered allergens, air filtration systems are crucial to prevent allergens from becoming airborne and contaminating other products.

• Allergen Control Plans: These plans outline procedures for handling, storing, and labelling allergens, ensuring the risks are managed at every production stage.

• Employee Training and Hygiene Protocols: Employees must be trained in hygiene practices such as regular handwashing, uniform changes, and proper tool cleaning. These measures are essential for preventing accidental allergen spread.

Regular audits and compliance with regulations from bodies like the Food Standards Agency (FSA) in the UK and the European Food Safety Authority (EFSA) in the EU are vital for maintaining allergen control. Audits help identify risks early and ensure corrective actions are taken, reducing the chances of allergen exposure, product recalls, and reputation damage.

Allergen contamination is a serious concern in food manufacturing. However, with proper allergen management practices and adherence to regulations, risks can be minimised, ensuring consumer safety and preserving the long-term integrity of the brand.
