Which of the following is prohibited in an establishment regarding neck dusters?

Using brush-type neck dusters is prohibited in an establishment for sanitation reasons. These types of dusters can harbor bacteria and other contaminants due to the bristles and their tendency to accumulate dust and debris from the environment. In settings such as food preparation or service, maintaining high standards of cleanliness is crucial to prevent any potential contamination of food products or surfaces.

Electric neck dusters, while not typically used in food establishments, are designed for easy cleaning and operation, making them less likely to pose a sanitation risk. Disposable neck dusters are often favored in many establishments because they are intended for single-use, minimizing cross-contamination. Therefore, the prohibition on brush-type neck dusters directly relates to the need for cleanliness and health safety standards in food service environments.
