How often should chemical sanitizer concentration be checked during use?

Chemical sanitizer concentration should be checked every shift to ensure that the sanitizer remains effective throughout its use. This practice is crucial because the concentration can diminish over time due to various factors such as evaporation or dilution. By checking the concentration at the beginning of each shift, food handlers can verify that the sanitizer meets the required levels to effectively kill harmful bacteria and pathogens on food contact surfaces.

Consistently checking the concentration helps maintain food safety standards and protects public health. It is also a best practice to incorporate this check into the daily routine of food safety protocols to avoid any lapses in sanitation during service hours. Regular monitoring ensures that staff are prepared to take corrective actions if the concentration is not within acceptable levels.
