Question

An employee wants to make a sanitizer solution to spray onto food-contact surfaces. What must be done to ensure that it has been made correctly?

Answer 1

To ensure that a sanitizer solution for food-contact surfaces has been made correctly, follow the correct concentration, mixing and handling procedures, and conduct a use-dilution test to measure effectiveness.

Step-by-step explanation:

To ensure that a sanitizer solution for food-contact surfaces has been made correctly, there are several important steps to take:

1. First, make sure to use the correct concentration of the sanitizing agent. The Association of Official Agricultural Chemists International (AOAC) recommends a 1:10 dilution of bleach or 1 N NaOH.
2. Next, follow the proper procedures for mixing and handling the solution. This may include wearing protective clothing and gloves, and using appropriate tools and containers.
3. Finally, it is important to test the solution to ensure its effectiveness. The use-dilution test is commonly used to measure the disinfection effectiveness of a chemical agent on surfaces. This involves dipping a stainless steel cylinder in a culture of the targeted microorganism, then in solutions of the sanitizer at various concentrations, and observing the presence or absence of turbidity in the medium.
