Square Pie Guys - At The Square

Official wording

Keep potentially hazardous foods (PHF) cold at 41°F or below or hot held at 135°F or above. Immediately discontinue storing PHF at room temperature.

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.
