After cooking or removal from hot holding, TCS food not cooled by an approved method whereby the internal temperature is reduced from 140 °F to 70 °F or less within 2 hours, and from 70 °F to 41 °F or less within 4 additional hours.
In plain English
Food was not kept cold enough, hot enough, cooled fast enough, or cooked or reheated to the right temperature. Bacteria grow quickly in the "danger zone" between 41°F and 135°F, which makes this one of the most important food-safety checks.
Food contact surface not properly washed, rinsed and sanitized after each use and following any activity when contamination may have occurred.
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.
