Final answer:
The acceptable contact time when sanitizing food-contact surfaces can vary depending on the specific disinfectant being used, but it is generally around 1-2 minutes. It is important to follow the instructions provided by the disinfectant manufacturer.
Step-by-step explanation:
The acceptable contact time when sanitizing food-contact surfaces can vary depending on the specific disinfectant being used. In general, the recommended contact time is around 1-2 minutes, but it is important to follow the instructions provided by the manufacturer of the disinfectant. Some disinfectants may require longer contact times to effectively kill bacteria and other microbes.
For example, a common disinfectant used in the food service industry is chlorine bleach. The recommended contact time for chlorine bleach is typically 1 minute. This means that the surface should be wet with the bleach solution for at least 1 minute before it is rinsed or wiped dry.
It is important to note that the contact time is just one factor that determines the effectiveness of a sanitizing process. Other factors, such as the concentration of the disinfectant, the temperature of the water used, and the cleanliness of the surface, can also affect the sanitization process.
