Sanitation controls are critical procedures, practices, and processes that ensure a facility is kept in a sanitary condition, significantly reducing or preventing hazards such as environmental pathogens, biological hazards from employee handling, and food allergen risks. These controls must be tailored to the specific needs of the facility and the food being processed. Key aspects of sanitation controls include:

1. Cleanliness of Food-Contact Surfaces: This involves ensuring that all food-contact surfaces, including utensils and equipment, are kept clean and sanitary. Effective sanitation practices help prevent contamination and maintain the integrity of food products.
2. Prevention of Allergen Cross-Contact and Cross-Contamination: It’s crucial to prevent cross-contact of allergens and cross-contamination between unsanitary objects, personnel, food, packaging materials, and surfaces. Special care must be taken to avoid contamination from raw to processed products.

However, the success of sanitation efforts depends heavily on the standards set by plant managers. If low standards are set, the entire sanitation program will suffer. 

Critical Components for Effective Sanitation

Effective sanitation is like building a strong house with three essential components:

• Sanitation Performance Standards: These are the foundational elements, such as the safety of the water supply and employee hygiene practices, that must be well-designed and maintained to support the overall sanitation structure.
• Sanitation Codes and Standard Operating Procedures (SSOPs): These serve as the “walls” of the sanitation program, outlining the specific actions to be taken before, during, and after production to maintain cleanliness and prevent contamination.
• Hazard Analysis and Critical Control Point (HACCP) Program: This is the structural framework that ties everything together, addressing environmental hazards and ensuring that all sanitation efforts are cohesive and effective.

How to Maintain an Efficient Sanitation Program

To implement a robust sanitation program, facilities can align their Sanitation Standard Operating Procedures (SSOPs) with the FDA’s sanitation control procedures outlined in 21 CFR, Part 123.11. While this section is focused on fish and fishery products, its principles can be applied to all food plants. The following key sanitation conditions and practices should be reviewed and monitored:

1. Water Safety: Ensure that all water used in food processing, including for cleaning and as ice, is from a sanitary source and safe for its intended use. This includes preventing cross-connections between potable water systems and waste or sewage lines.
2. Condition and Cleanliness of Food-Contact Surfaces: Regular pre-operational cleaning and sanitizing are vital. The success of these efforts hinges on consistent implementation and monitoring, without letting production pressures undermine food safety.
3. Prevention of Cross-Contamination: Cross-contamination risks should be addressed holistically, considering everything from employee traffic patterns to the separation of raw and cooked products. Facilities must maintain a strict separation of potentially contaminating items to ensure product safety.
4. Hand Washing/Sanitizing and Toilet Facilities: Employees must have access to well-maintained and easily accessible hand-washing and toilet facilities. These facilities should be designed to minimize the risk of recontamination, with hands-free controls and clear signage promoting good sanitation practices.
5. Protection from Adulteration: Food, packaging, and contact surfaces must be protected from contamination by environmental pathogens. A master sanitation schedule is essential to ensure that all areas, including often-overlooked spaces like storage coolers, are regularly cleaned and sanitized.
6. Proper Handling of Toxic Compounds: Toxic chemicals must be stored separately from food products in labeled containers and used according to their directions. Ensuring that cleaning agents are fully removed after use is also critical to prevent contamination.
7. Employee Health and Hygiene: Employees must be trained in proper hygiene and food handling practices, with ongoing education to ensure compliance. Supervisors should monitor and enforce these practices, correcting issues as they arise.
8. Pest Exclusion: Facilities must take measures to exclude pests from all areas, employ licensed pest management professionals, and implement pest-proofing strategies.

Finally, the sanitation control procedures outlined in section 123.9 emphasize the importance of maintaining records to document the monitoring and correction of these eight key controls. A strong sanitation program, supported by well-defined standards, practices, and ongoing vigilance, is essential for ensuring food safety and preventing contamination.
