Official wording

Ensure all food is separated and protected from potential cross contamination. Store produce and ready-to-eat foods completely separate or above raw foods including but not limited to raw eggs, fish, meat, ratites, game animals, and poultry. Provide adequate sneeze-guard protection, a container that has a tight fitting and securely attached lid, or dispense food from an approved mechanical dispenser.

In plain English

Food was stored or handled in a way that could let germs or other material get into it, such as raw meat stored above ready-to-eat food or uncovered food. Cross-contamination is a common cause of foodborne illness.
