Official wording

Discontinue thawing potentially hazardous foods at room temperature or in standing water. Use one of the following approved methods: - Under potable running water of sufficient velocity to wash away loose food particles using water no greater than 70°F for no more than 2 hours. - In a refrigeration unit at 41°F or below - In a microwave - As part of the cooking process

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.
