Physical hazards do not include ___.

Physical hazards refer to any objects that can inadvertently contaminate food and pose a risk to consumers. The option indicating "bleeding cuts on the hands" is not classified as a physical hazard for food; rather, it relates to the physical condition of the food handler. While a bleeding cut may pose a risk of biological contamination if it comes into contact with food, it is not an object or external item that can be considered a physical hazard.

In contrast, other choices like hair, bandages, accumulated dust, and unprotected lights are all tangible items that can physically contaminate food if they fall or dislodge into food preparation areas, thus making them physical hazards. Maintaining a safe food handling environment necessitates that food handlers be aware of the risks posed by these physical contaminants, as well as practicing proper hygiene to avoid biological hazards.
