When should sanitizing solutions typically be changed in a food service environment?

Sanitizing solutions should typically be changed every 2 to 3 hours in a food service environment to ensure effective sanitation. Over time, the efficacy of the sanitizing solution can diminish due to factors like dilution, contamination from surfaces, and exposure to air. Regularly changing the solution helps maintain a consistent concentration that is necessary to effectively kill harmful microorganisms on food contact surfaces, utensils, and equipment. This practice aligns with health and safety guidelines, which emphasize the importance of using freshly prepared or appropriately maintained sanitizing solutions to uphold food safety standards.
