Light fixtures must be covered to prevent which type of contamination?

Light fixtures must be covered to prevent physical contamination in food service environments. Open light fixtures can result in the drop of light bulbs, glass, or other fragments that may inadvertently contaminate food products or food preparation surfaces. Physical contaminants are solid objects that can pose a risk if they find their way into food, causing injury to consumers or compromising food safety.

Covering light fixtures minimizes this risk significantly, ensuring that any broken parts remain contained and do not fall into food areas. This approach contributes to maintaining a safe environment, essential for food safety management.

Biological contamination typically involves microorganisms, chemical contamination pertains to harmful substances, and radiological contamination involves radioactive materials. While all are crucial considerations, the specific concern addressed by covering light fixtures is the prevention of physical contamination.
