Which of the following is evidence of deliberate tampering of food?

Food defense is the protection of food products from intentional contamination by biological, chemical, physical, or radiological agents. While "accidental" contamination (like a hair in a soup) is common, "deliberate tampering" is an act of sabotage. According to the ServSafe Manager guidelines and the FDA’sA.L.E.R.T.program, one of the most visible signs of tampering is amissing or broken protective seal or wrapperon a food container. These seals are designed to guarantee the integrity of the product from the manufacturer to the end-user. If a seal is broken, it suggests that an unauthorized individual may have had access to the contents.

Managers must train receiving staff to inspect all incoming deliveries specifically for signs of tampering. This includes checking for punctured packaging, leaking containers, or boxes that appear to have been resealed with non-factory tape. While missing labels (Option A) are a regulatory violation and bare-hand contact (Option D) is a hygiene failure, they do not necessarily indicate a malicious attempt to harm the public. Adding sulfites (Option B) is actually a prohibited practice for fresh produce in many jurisdictions, but it is a chemical additive issue rather than tampering. To mitigate the risk of deliberate contamination, the A.L.E.R.T. system suggests that managers:Assure products are from safe sources,Look and monitor the security of the facility,Employees (know who is in the building),Report and keep records, andThreat (know what to do if a threat occurs). Isolating and reporting any products with suspicious packaging is a mandatory step in protecting the business and its customers from intentional harm.
