Which of the following is NOT a recommended measure to reduce insider adulteration risk?

• A. Limit access to storage areas based on job function
• B. Allow unrestricted personal items in work areas
• C. Secure cleaning supplies/pesticides/lab reagents
• D. Maintain inventory records to enable discovery and investigation of missing materials

Answer: (B)

Insider adulteration risk is reduced by restricting who can access materials, securing potentially harmful substances, and keeping tight records of inventory so discrepancies are detectable. Limiting access to storage areas based on job function directly lowers the chance that someone can reach materials they shouldn’t handle. Securing cleaning supplies, pesticides, and lab reagents prevents easy diversion or tampering and makes it harder for someone to misuse items. Maintaining inventory records provides a trail that helps identify missing materials and supports investigations when something goes off track.

Allowing unrestricted personal items in work areas undermines all of these controls. Personal items can conceal tools or substances, facilitate tampering, and hinder monitoring and accountability, making it easier for adulteration to go undetected. Therefore, this practice is not a recommended measure.
