El Gallo Taqueria

Official wording

TCS food removed from cold holding or prepared from or combined with ingredients at room temperature not cooled by an approved method to 41 °F or below within 4 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.
