Which of the following is a requirement for chemical sanitization?

A requirement for chemical sanitization is that the solution must be tested for concentration. This is crucial because the effectiveness of chemical sanitizers depends largely on their concentration levels. If the concentration is too high, it can be harmful and potentially leave residues that could contaminate food. If it is too low, it may not effectively kill harmful microorganisms. Testing for the correct concentration ensures that the sanitizer works effectively to disinfect surfaces and equipment, thus maintaining hygiene and preventing foodborne illnesses.

Assessing the concentration is typically done using test strips or kits that provide immediate feedback, allowing food handlers to adjust the solution as necessary to ensure it meets safety standards.
