Which of the following is a recommended practice to reduce insider adulteration risk?

• A. Limit access to storage areas based on job function
• B. Expand break times to every hour
• C. Allow all personal items at all times
• D. Increase the number of delivery receipts required

Answer: (A)

Limiting access to storage areas based on job function reduces insider adulteration risk by enforcing the principle of least privilege. When only people whose roles require entering sensitive spaces can do so, the number of individuals who could tamper with ingredients, products, or equipment is minimized. This tighter access makes it easier to monitor activity, hold people accountable, and quickly detect unusual behavior. In practice, assign access by role, use secure doors or card access, and require authorization for entry, paired with routine audits and supervision.

The other options don’t directly prevent tampering. Expanding break times can increase opportunities for unsupervised activity. Allowing personal items at all times raises the risk of contamination or concealment of adulterants. Increasing the number of delivery receipts improves traceability but doesn’t reduce the opportunity for insider tampering.
