Short Answer 
Properly identifying signs of pest activity in food operations is crucial, with paper straps indicating rodent nesting. However, not all indicators, like oily substances or electrical smells, are pest-related; some point to maintenance issues. Differentiating between these signs helps maintain a safe and hygienic environment.
Step 1: Recognizing Indications of Pest Activity
Identifying signs of pests in food operations is critical. One significant indicator is the presence of paper straps found balled up in drawers. This behavior often points to nesting by rodents, which can compromise the hygiene of food handling environments.
Step 2: Discerning Other Non-Pest Indicators
Not all signs indicate pest activity. For instance, an oily substance dripping from a range hood suggests poor maintenance rather than pest infestation. Similarly, an electrical smell under equipment may signal wiring issues, which are unrelated to pests.
Step 3: Observing Other Potential Issues
Additional observations such as small pin holes in sink plumbing can hint at various maintenance issues, not necessarily linked to pest presence. Understanding these differences is vital for ensuring a safe and hygienic environment in food operations.
