Good Manufacturing Practices, or GMPs, are the minimum sanitary and processing requirements issued by the FDA (under section 520 of the Food, Drug and Cosmetic Act) that a company must uphold.
Within the foodservice industry these typically consist of maintaining a clean kitchen, safe water supply, good personal hygiene of all employees, consistent and thorough employee training system, and an up-to-date pest control program. Most foodservice industry companies use GMPs to write more specific Standard Operating Procedures (SOPs) and to implement a comprehensive food safety program.
