Which tests may be used as optional verification for allergen cleaning?

• A. ATP and protein tests
• B. colorimetric surface tests
• C. soil residual testing only
• D. none of the above

Answer: (A)

Verifying allergen cleaning can be done with tests that both broadly assess cleanliness and specifically target allergen residues. ATP testing provides a rapid read on surface cleanliness by detecting residual organic material, which helps flag surfaces that may not have been cleaned thoroughly. Protein testing, on the other hand, detects actual allergenic proteins on surfaces, offering specificity to the presence of allergen residues. Using these two together gives a practical verification approach: ATP for general cleanliness and a protein test to confirm removal of allergen residues. Colorimetric surface tests aren’t as specific for allergens, and soil residual testing isn’t a standard method for verifying allergen cleaning, so they’re not the preferred option.
