Which of these is NOT considered a potential physical hazard?

Physical hazards in food safety refer to any objects that can potentially cause harm or injury to consumers. The correct choice, which is pesticides, is not a physical hazard; instead, it is classified as a chemical hazard.

Pesticides are chemical substances used to kill pests that can affect crops. While they can pose significant health risks if ingested in unsafe quantities, they do not fall within the category of physical objects that might cause choking or injury.

In contrast, options such as fake nails, plastic pieces from packaging, and cherry pits are all physical items that can directly interfere with food safety. Fake nails can break off and end up in food, while plastic from packaging can contaminate food products. Cherry pits pose a risk of choking and can cause injury if bitten into. This context highlights the distinction between physical and chemical hazards in food safety practices.
