Which item is NOT a sign of pest infestations in food facilities?

Unused equipment is not a direct sign of pest infestations in food facilities. While it is important to monitor and manage unused equipment in food establishments, its presence alone does not indicate that pests are currently infesting the area. Pests like rodents and insects typically leave behind more immediate and obvious signs of their presence. For instance, droppings indicate an active infestation, as they show where pests have been. Nesting materials can be a strong indicator as well, as they suggest that pests are not only present but also potentially breeding. Similarly, larvae are a clear sign of an insect problem, indicating that pests are reproducing within the facility. Thus, while unused equipment may contribute to unsanitary conditions or be a potential harboring site for pests if not managed properly, it does not by itself demonstrate an active pest infestation.
