Final answer:
Food-contact surfaces must be cleaned and sanitized at least every four hours when in constant use.
Explanation:
Food-contact surfaces, such as countertops, cutting boards, and utensils, must be cleaned and sanitized regularly to prevent the growth and spread of harmful bacteria. Cleaning involves removing dirt, debris, and visible contaminants from the surface, while sanitizing involves reducing the number of bacteria to safe levels.
When in constant use, food-contact surfaces should be cleaned and sanitized at least every four hours. This frequency ensures that any potential contamination is minimized, reducing the risk of foodborne illnesses.
It is important to follow proper cleaning and sanitizing procedures, which may include using hot water and soap for cleaning, followed by a sanitizing solution or heat treatment. Different establishments may have specific guidelines and regulations in place, so it is essential to adhere to those guidelines to maintain food safety standards.
