What is a possible indication of pest presence in a food establishment?

Evidence of droppings is a significant indication of pest presence in a food establishment. Pests such as rodents and insects leave behind droppings, which can be a clear sign of an infestation. Noticing droppings can alert staff to the likelihood of pests inhabiting the area, prompting measures such as inspections, sanitation, and pest control strategies to be implemented. Recognizing this sign early can help prevent further infestation and protect food safety within the establishment.

In contrast, unused kitchen tools do not typically indicate pest activity, as they can simply suggest a lack of recent cooking or preparation. Inconsistent staff shift patterns might affect service but are not directly related to pest presence. Similarly, the presence of customers does not provide information about pests; rather, it is a normal aspect of any food establishment's operation.
