ServSafe Allergens — All Questions

Why is thorough cleaning, not just sanitizing, essential for removing food allergens from a surface?

• a.Sanitizers chemically destroy allergen proteins on contact
• b.Sanitizers are designed to reduce pathogens, but only cleaning physically removes the allergen residue✓
• c.Allergens are killed by heat during sanitizing
• d.Cleaning and sanitizing have the same effect on allergens

Sanitizing reduces pathogens to safe levels but does not reliably remove or destroy allergen proteins. Only physical cleaning, washing with detergent and water to lift and wash away the residue, actually removes the allergen from a surface. That is why an allergen-safe workflow is wash, rinse, sanitize, and air dry, with the emphasis on genuinely removing residue, not merely killing microbes.

Which item is the safest choice for cleaning up an allergen spill to avoid spreading it to other surfaces?

• a.A shared wiping cloth kept in sanitizer buckets between tasks
• b.A dry towel reused across multiple stations
• c.Single-use disposable paper towels discarded after the wipe✓
• d.A sponge rinsed under the tap

Single-use disposable towels are safest because they are thrown away after one use, so they cannot carry allergen residue to another surface. Shared wiping cloths and reused towels move allergen protein from station to station, and sponges trap residue that a quick rinse will not remove. When single-use towels are not available, a cloth must be laundered or replaced, not reused across allergen-free prep.

What is the correct general order of steps when manually cleaning and sanitizing equipment used with an allergen?

• a.Wash with detergent, rinse, sanitize, then air dry✓
• b.Sanitize, wash, then towel dry
• c.Rinse, air dry, then sanitize
• d.Sanitize only, since the equipment looks clean

The correct sequence is wash (detergent and water to remove residue), rinse, sanitize, then air dry. For allergens the washing step is what actually removes the allergen protein; sanitizing alone will not. Air drying avoids re-contaminating with a shared towel. Skipping steps, or sanitizing without washing first, leaves allergen residue that can reach an allergic guest.

Before preparing an allergen-free order, what should a food handler do about their gloves and hands?

• a.Keep the same gloves to save time if they look clean
• b.Rinse gloved hands in the same water used for other prep
• c.Only change gloves if food is visibly on them
• d.Wash hands and put on a fresh pair of clean gloves✓

Hands and gloves are a common cross-contact route, so the handler should wash their hands and put on a fresh pair of clean single-use gloves before preparing an allergen-free order. Gloves that touched other foods carry allergen protein even when they look clean, and rinsing does not remove it. Gloves are not a substitute for handwashing; the two work together.
