Short Answer 
To identify pest signs in a food handling environment, look for key indicators such as paper scraps in drawers, which suggest rodent activity. Additionally, monitor for visual sightings of pests, droppings, and damaged goods while distinguishing these signs from general maintenance issues.
Step 1: Recognize Key Indicators
In a food handling or preparation environment, it’s essential to be aware of signs indicating pest activity. The most telling sign among the options is the presence of paper scraps balled up in a drawer. This usually suggests that rodents or insects are using these scraps to build nests, signaling an immediate need for pest control.
Step 2: Look for Additional Signs
Beyond paper scraps, monitor for other clear indicators of pests in your space. These can include:
- Visual sightings of the pests themselves, such as mice or insects.
- Droppings or frass, which are signs of rodent or insect presence.
- Damaged goods, especially food items that show signs of gnawing or contamination.
Step 3: Differentiate from Maintenance Issues
It’s important to distinguish pest signs from general maintenance problems. Other options provided, like small pinholes in plumbing or oily substances, typically relate to non-pest issues. Focus on the most relevant signs to efficiently tackle pest problems and maintain a safe, hygienic environment.
