What do 'in-use' sanitizer controls refer to?

'In-use' sanitizer controls specifically refer to the practice of monitoring sanitizer concentration during use. This is essential for ensuring that the sanitizer is effective in killing or inactivating pathogens present on surfaces. Proper concentration levels are necessary to meet recommended guidelines for different types of sanitizers, as both under-concentration and over-concentration can lead to ineffective sanitation or potential hazards, respectively.

Monitoring the concentration regularly ensures that the sanitizers are maintained within required parameters, which is critical for food safety and public health. It also allows for timely adjustments to be made if concentration levels drift outside of the recommended range, thereby maintaining an effective sanitation environment.
