Which of the following may indicate a product is suspicious and should be quarantined until investigated?

• A. The bottle has tape or adhesive residue on the outside.
• B. The bottle label is damaged due to moisture
• C. The bottle is a different color than usual
• D. The bottle is unopened but appears intact

Answer: (A)

A bottle with tape or adhesive residue on the outside is the strongest indicator of tampering and should trigger quarantine and investigation. That outside residue suggests the container may have been opened, resealed, or altered, which raises concern about the contents’ integrity. In practice, you’d isolate the product, document what you see, and escalate to a supervisor to verify the lot, expiration, and packaging integrity before any use or distribution.

Moisture damage to a label can make the label unreadable and raise questions about storage conditions, but it doesn’t by itself prove tampering. A different color might be due to lighting, aging, or legitimate packaging changes, not necessarily tampering. An unopened, intact bottle looks non-suspicious at first glance, though nothing can be ruled out without verification.
