Sanitation is one of the most important, if not the most important, departments in the food manufacturing plant. The actions of sanitation personnel mean that production starts the day with clean equipment and a clean environment, and this helps maintain sanitary conditions during operations to prevent food safety hazards or quality failures.

Errors involving product contamination, misbranding, and undeclared allergens remain the three leading causes of food recalls. Since employees are the cornerstone for preventing allergen and gluten adulteration, providing proper training to staff can prevent errors that could lead to a recall.
