Which of the following is a sign of pest infestation?

Chewed packaging and droppings are clear signs of pest infestation. When pests, such as rodents or insects, invade a food service environment, they often leave behind physical evidence of their presence. Chewed packaging indicates that pests have accessed food or storage areas, which can lead to contamination of products. Droppings, in particular, are a telltale sign of rodents and insects, as they not only indicate that pests are present but also pose a serious health risk due to the potential transmission of diseases. Recognizing these signs is crucial in maintaining food safety and preventing further infestation.

In contrast, high customer satisfaction does not indicate pest activity; it relates more to the overall dining experience. Frequent power outages can affect food storage, but they do not directly show an infestation. Increased food waste may occur for various reasons, including spoilage or overpurchasing, but it does not specifically signify pests. Thus, identifying chewed packaging and droppings is vital for food safety and sanitation practices.
