Grill-N-Chill

Official wording

Potentially hazardous foods are not stored under refrigeration except during necessary preparation or approved precooling procedures (room temperature storage).

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.
