Physical contamination can be reduced by which of the following practices?

Preventing physical contamination involves removing potential foreign objects: not wearing jewelry that can fall in, using shatter-resistant light shields, keeping fingernails trimmed, and inspecting food for bones, pits, or packaging. Leaving salads out at room temperature is a time-temperature failure, rinsing raw chicken sprays pathogens around the sink instead of removing them, and salt does nothing to a metal shaving or a glass shard — none of the three removes a foreign object.
