Jun 10, 2025

Overview

This lecture covers the basics of food allergens, their risks, prevention methods, and procedures for managing allergen information in food service environments.

Introduction to Food Allergens

  • Food allergens are substances in food that trigger immune responses in sensitive individuals.
  • Reactions can range from mild symptoms to severe, life-threatening anaphylaxis.
  • Even small amounts of an allergen can cause a reaction.

Common Food Allergens

  • The most common food allergens include peanuts, tree nuts, milk, eggs, fish, shellfish, soy, and wheat.
  • Some regions require disclosure of additional allergens, such as sesame, lupin, or mustard.

Symptoms of Allergic Reactions

  • Mild symptoms can include itching, hives, swelling, or stomach pain.
  • Severe reactions include difficulty breathing, drop in blood pressure, or loss of consciousness (anaphylaxis).

Prevention and Cross-Contamination

  • Preventing cross-contact is critical—use separate utensils and equipment for allergen and non-allergen foods.
  • Clean work surfaces and wash hands regularly to reduce risk.
  • Clearly label all foods with potential allergens.

Allergen Management Procedures

  • Provide accurate allergen information to customers; use up-to-date ingredient lists.
  • Train staff to respond appropriately to allergen inquiries and emergencies.
  • Have procedures in place for handling allergic reactions, including access to emergency medication.

Key Terms & Definitions

  • Allergen — a substance that causes an allergic reaction.
  • Anaphylaxis — a severe, potentially life-threatening allergic reaction.
  • Cross-contact — accidental transfer of allergens from one food or surface to another.

Action Items / Next Steps

  • Review your facility's allergen management policy.
  • Complete assigned allergen awareness training.
  • Practice clear labeling and communication regarding food ingredients and allergens.
