Plumbing properly sized, installed, and maintained; proper backflow devices, indirect drains, no cross-connections
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.
Staff were not washing their hands when required, or a handwashing sink was blocked, missing soap or paper towels, or used for something else. Hands are one of the most common ways germs reach food.
