Which of the following are examples of allergenic hazards?

• A. Bacteria, Viruses, Moulds, Parasites
• B. Peanuts, Tree Nuts, Sesame Seeds, Eggs, Milk
• C. Glass, Screws, Stones, Hair
• D. Lye, Bleach, Ammonia, Acids

Answer: (B)

Allergenic hazards are substances that can trigger immune reactions in sensitive individuals, typically specific foods known to cause allergies. The set that includes peanuts, tree nuts, sesame seeds, eggs, and milk lists common food allergens that people must be protected from through proper controls. In HACCP terms, these require prevention of cross-contact, clear labeling, and careful handling to keep allergens out of foods that aren’t intended to contain them, or to ensure ingredients are accurately identified.

The other groups aren’t allergenic hazards in this context: one is composed of microorganisms and parasites (biological hazards), another lists physical contaminants like glass and hair, and the last contains chemicals like lye and ammonia. Each represents a different type of hazard, but not an allergenic one.
