Official wording

All temporary food facilities that handle nonprepackaged food shall provide floors constructed of concrete, asphalt, tight wood, or other similar cleanable material kept in good repair. Temporary food facilities shall be equipped with overhead protection for all food preparation, food storage, and warewashing areas. Overhead protection shall be made of wood, canvas, or other materials that protect the facility from precipitation, dust, bird and insect droppings, and other contaminants. Based upon local environmental conditions, location, and other similar factors, the enforcement officer may establish additional structural or operational requirements, or both, as necessary to ensure that foods are of a safe and sanitary quality.

In plain English

The inspector found mice, rats, cockroaches, flies, or evidence of them (like droppings) inside the business, or conditions that could attract them. Pests can spread bacteria to food and surfaces, so this is treated as one of the more serious findings.
