What is a minimum criterion for verifying allergen cleaning?

• A. visually clean (no residue, film or sheen)
• B. mandatory genetic testing of surfaces
• C. requirement for third-party certification only
• D. no verification is required

Answer: (A)

The minimum criterion for verifying allergen cleaning is that surfaces appear visually clean—no residue, film, or sheen. This quick, non-destructive check provides an immediate sanity test that cleaning procedures were followed and the area looks clean enough to proceed. It sets a practical baseline before more rigorous verification is pursued. More robust verification would involve actual allergen testing (such as swab sampling and an appropriate assay) or other external validations, but those go beyond the minimum standard. Visual cleanliness is not about detecting traces with lab tests, so the other options—genetic testing of surfaces, requiring third-party certification, or having no verification at all—do not fit as the simplest, everyday minimum criterion.
