Orange County stands apart in Southern California by not requiring visible letter grade health ratings for its restaurants and food establishments. This situation leaves diners "completely in the dark" regarding food safety, according to proponents advocating for a new system.

Every single county surrounding Orange County—including Los Angeles, San Diego, Riverside, and San Bernardino—utilizes a highly visible, universal A, B, or C letter grading system. Orange County, by contrast, relies on a system described as "opaque," involving hidden certificates and vague online reports.

Efforts to establish restaurant letter grades in Orange County are not new. In 2008, the Orange County Grand Jury "strongly urged" the county to mandate highly visible letter grades.

A key vote against consumer transparency at that time came from current First District Supervisor Janet Nguyen. The source material states that Nguyen "fiercely defended restaurant owners against public grading" while actively concealing a "massive conflict of interest." It was later revealed that her husband, Thomas Bonikowski, and her chief of staff—the now-convicted former supervisor Andrew Do—were hidden co-owners of a Lee’s Sandwiches franchise in Stanton. This establishment reportedly suffered an "atrocious health violation record," which the source states heavily disincentivized Nguyen from backing open inspection metrics. Public records also showed Nguyen received thousands of dollars in campaign contributions directly from various local restaurant owners who possessed documented, poor health inspection records. Andrew Do is currently serving a federal prison sentence for public corruption and bribery. The source argues the Board of Supervisors must explicitly distance itself from this "legacy of self-dealing" by prioritizing public safety.

Failing to implement transparent letter grade ratings is said to directly impact human health. The source points to steady escalations in outbreaks of foodborne illnesses from dangerous pathogens like Salmonella, E. coli, and Norovirus. Restaurants operating with subpar sanitation practices, improper holding temperatures, and unhygienic food preparation spaces are described as "breeding grounds" for these preventable diseases.

A visible letter grade posted directly in a storefront window is presented as an "immediate deterrent to negligence," compelling restaurant management to maintain basic compliance. The source cites "peer-reviewed data across neighboring counties" which demonstrates that the introduction of mandatory letter grades rapidly forces restaurants to improve cleanliness. This, in turn, leads to a "direct and measurable decrease in local foodborne illness hospitalizations." Proponents argue that Orange County residents deserve the exact same layer of public health security enjoyed by diners in neighboring areas.

The current Orange County Board of Supervisors possesses the legislative authority to pass a consumer protection ordinance to implement these grades. Residents are being encouraged to contact their representatives to demand a vote on enforcing mandatory, visible letter grade health ratings for local food establishments.
