It is important to maintain safe facilities. The GMPs for facilities could be grouped in many ways, but one way to consider them might be: Inside, Outside, Pest Management and Sanitation.
GMPs listed for the plant and grounds help ensure that the building and structures are suitable for food production and reduce the potential for pathogens to contaminate food. For example, GMPs call for workers to make sure that the grounds outside the food facility are clean, prevent standing water and collect and remove waste on a regular schedule. Inside the facility, GMPs call for adequate space and proper separation of operations.
