Each establishment that has a restaurant permit must be evaluated by a Registered Environmental Health Specialist (REHS)from the health department. The REHS makes an unannounced inspection to evaluate the restaurant for compliance with the regulations. The focus of the inspection is to ensure that the operation is practicing safe food preparation methods including refrigeration temperatures, hot-holding temperatures, cooking temperatures and cooling methods, food worker hygiene, and safe food sources. Any rule violations are summarized on an inspection sheet, and an overall score is computed. A perfect score is 100%. The inspection grades are then posted for public viewing at the establishment and can also be seen on the Internet.
