Osha Thai Restaurant Failed with Cockroaches Throughout Kitchen

250 Montgomery Osha Thai in San Francisco's Financial District failed a routine health inspection on October 1, 2025, after inspectors discovered dead cockroaches throughout the kitchen and food storage areas. The Thai restaurant, located at 250 Montgomery Street near Montgomery St BART, received eight violations during this inspection, including one major violation for pest infestation.

Cockroach Infestation Throughout Kitchen

Inspector Alyssa Manzano documented the most serious violation when she found dead cockroaches scattered across multiple areas of the restaurant's food preparation and storage zones. The pest problem extended throughout the kitchen, with dead cockroaches discovered on the floor behind cooking equipment, inside the walk-in cooler where food is stored, on the floor next to the grease trap, and underneath a hand sink adjacent to the espresso machine. Most concerning was the discovery of a dead cockroach on a monitoring trap underneath the hand sink next to the walk-in cooler, indicating the infestation had spread to critical food safety areas. The presence of cockroaches in these locations poses serious health risks to customers, as these insects carry 33 different types of bacteria and six parasitic worms that can cause foodborne illness. While the person in charge provided a pest control report dated September 29, just two days before the inspection, the continued presence of dead cockroaches suggests ongoing pest control issues. The inspector noted that affected areas were cleaned and sanitized during the inspection and recommended continuing routine licensed pest control services.

Food Safety Equipment Violations

Beyond the cockroach problem, inspectors found significant issues with food contact surfaces that could contaminate meals served to customers. The ice machine showed accumulation of buildup on the top interior panel and deflector, creating potential breeding grounds for bacteria in ice that would be served with drinks. Additional violations included improper storage of employee drinks above customer food in the undercounter refrigerator, creating cross-contamination risks. Four hand sinks were missing paper towels, and one hand sink lacked soap entirely, preventing proper handwashing protocols that are critical for preventing foodborne illness.

Maintenance and Cleanliness Issues

The inspection revealed broader maintenance problems throughout the restaurant. Grease had accumulated on exhaust hood filters above the cooking line and dish machine, compromising ventilation systems. Floors behind cooking equipment showed grease buildup, creating slip hazards and unsanitary conditions. A leaking flip-top preparation cooler at the cook's line posed additional food safety concerns, while household pesticide spray found in the utility closet violated commercial food service regulations. One employee was observed improperly rinsing a rubber mat in a hand sink designated solely for handwashing.

First Inspection Record

This represents the first recorded health inspection for 250 Montgomery Osha Thai, making it impossible to determine if these violations represent ongoing issues or recent developments. The restaurant's person in charge, Puck Ananta, refused to sign the inspection report. The failed inspection highlights ongoing concerns about food safety standards in the Financial District, where office workers and tourists rely on quick dining options. Customers who ate at this Thai restaurant before the violations were corrected may have been exposed to contaminated food and surfaces.
