Final answer:
Regulatory enforcement agencies like OSHA and FDA establish the necessary controls to ensure periodic inspections are accomplished.
Step-by-step explanation:
The necessary controls to ensure periodic inspections are accomplished are established by regulatory enforcement agencies like OSHA (Occupational Safety and Health Administration) and FDA (Food and Drug Administration). These agencies have the authority to enforce laws and regulations related to workplace safety and the purity, effectiveness, and labeling of food, drugs, and cosmetics. Compliance Safety and Health Officers from OSHA carry out inspections and assess fines for regulatory violations, while FDA inspects the production and shipment of these products.
