Restaurants and other retail food establishments fall under state law and are regulated by state or local health departments. Typically these regulations require official inspections of specific design features, best food-handling practices, and certification of food handlers. In some places a letter grade or numerical score must be prominently posted following each inspection. In some localities, inspection deficiencies and remedial action are posted on the Internet. In addition, states may maintain and enforce their own model of the FDA Food Code. For example, California maintains the California Retail Food Code (CalCode), which is part of the Health and Safety Code and is based on most current and safe food handling practices in the retail industry.
