Allergens are substances that can provoke allergic reactions in certain individuals. For those affected, even trace amounts of these allergens can cause mild to severe symptoms, ranging from skin irritation and gastrointestinal distress to life-threatening anaphylaxis. Understanding allergens and how they are managed in food production is essential for ensuring consumer safety.
What Are Allergens?
Allergens are typically proteins found in certain foods that trigger an immune response in sensitive individuals. These reactions occur because the body mistakenly identifies these proteins as harmful, leading to the release of histamines and other chemicals that cause allergy symptoms.
Why Is Allergen Management Crucial in Food Production?
In the context of food safety, allergen management is a critical part of Hazard Analysis and Critical Control Points (HACCP) protocols. HACCP involves identifying potential hazards, implementing controls to mitigate these risks, and ensuring compliance with food safety regulations.
For allergens, this means:
Identifying allergenic ingredients in recipes and raw materials.
Preventing cross-contact during production.
Ensuring proper labeling to inform consumers about potential allergens in the product.
The 14 Major Food Allergens
Regulations in many countries, including the European Union, require that food producers declare the presence of the following 14 major allergens on product labels to ensure consumer safety:
Cereals Containing Gluten (e.g., wheat, barley, oats): Found in bread, pasta, and baked goods, gluten can trigger reactions in individuals with celiac disease or wheat allergies.
Shellfish and Shellfish Products 🦐: Commonly found in seafood dishes, shellfish are a potent allergen that includes shrimp, crab, and lobster.
Eggs and Egg-Based Products 🍳: Present in baked goods, sauces, and mayonnaise, egg allergies are prevalent, particularly in children.
Peanuts and Peanut Products 🥜: Often hidden in snacks, sauces, and desserts, peanuts are one of the most severe allergens.
Fish and Fish Products 🐟: Found in dishes like sushi, fish sauces, and soups, fish allergies can be triggered even by steam or smell.
Soya and Soya Products 🌽: A common ingredient in Asian cuisine, plant-based foods, and processed items, soy can cause allergic reactions.
Milk and Milk-Based Products (including lactose): Dairy is a key allergen, appearing in cheese, yogurt, and many processed foods.
Nuts (e.g., almonds, hazelnuts 🌰, walnuts, and cashews): Frequently found in desserts, chocolates, and spreads, nuts can cause severe reactions.
Celery and Celery Products: Common in soups, sauces, and spice mixes, celery allergies are lesser-known but significant.
Mustard and Mustard-Based Products: Present in condiments, marinades, and spice blends, mustard can provoke allergies.
Sesame Seeds and Sesame Seed Products: Found in breads, crackers, and ethnic foods like hummus, sesame is a growing allergen.
Sulphur Dioxide and Sulphites (in concentrations >10 mg/kg or 10 mg/l): As preservatives in dried fruits, wines, and canned goods, sulphites can trigger respiratory issues.
Lupins and Lupin Products: A legume used in gluten-free and vegan products, lupin can cross-react with peanut allergies.
Molluscs and Mollusc Products: This group includes clams, mussels, squid, and snails, commonly found in seafood dishes.
Preventing Allergen Risks
Here are key strategies for managing allergens in food production:
Thorough Cleaning: Prevent cross-contact by cleaning equipment and surfaces between production runs.
Segregation: Store allergenic ingredients separately and use dedicated tools.
Accurate Labeling: Ensure allergen information is clear and compliant with regulations.
Staff Training: Educate employees about the importance of allergen management and proper procedures.
As consumers, it’s crucial to read labels carefully and ask questions when dining out. For individuals with food allergies, carrying emergency medication and wearing medical alert bracelets can be lifesaving.
Allergens are a significant concern in the food industry, but risks can be minimized with proper management and consumer awareness. Understanding the nature of allergens and adhering to food safety protocols can create a safer environment for everyone.
