SEBASTIAN, FL. Inspectors who walked into Khob Khun Thai Sushi on US Highway 1 on August 11, 2026, found food coming from unapproved or unknown sources, a violation that means the restaurant could not confirm where some of its ingredients originated or that they had passed any federal safety inspection. The facility logged six high-severity violations and five intermediate violations that day. It was not closed.
That same day, it was also shut down for rodent, roach, and fly activity. It reopened the following morning.
What Inspectors Found
The unapproved food source violation is the one that most directly undermines any assumption of safety. Food that bypasses USDA and FDA inspection has no verified chain of custody. If a customer became sick, investigators would have no reliable way to trace the ingredient back to its origin.
The undercooking violation compounded that risk. A restaurant serving sushi alongside cooked Thai dishes is already operating in a high-complexity environment. When food is not brought to minimum required temperatures, pathogens including Salmonella in poultry can survive and reach the plate.
Toxic chemicals stored improperly near food areas represent a separate, acute danger. A mislabeled or misplaced chemical can contaminate food without any visible sign, and the result can be immediate poisoning rather than the delayed onset typical of bacterial illness.
The restaurant also failed to post a consumer advisory for raw and undercooked foods. A Thai-sushi concept regularly serves raw fish. Elderly diners, pregnant women, and anyone with a compromised immune system are entitled to that warning before they order.
What These Violations Mean
The combination of unapproved sourcing and undercooking is particularly serious in a restaurant that serves raw and cooked proteins side by side. Food from unknown sources may already carry bacterial loads above what proper cooking would neutralize, and when cooking temperatures are also insufficient, there is no backstop.
Improper handwashing technique deserves attention on its own. The violation is not that employees skipped handwashing entirely. It is that they washed incorrectly, leaving pathogens on hands they believed were clean. That is a harder problem to catch and a harder habit to break.
The sewage disposal violation introduces a contamination pathway that most diners would find alarming. Improper wastewater handling can place fecal bacteria in proximity to food preparation surfaces. Combined with improperly cleaned multi-use utensils and reused single-use items, the August 11 inspection documented multiple overlapping contamination routes operating simultaneously.
Wiping cloths used improperly move bacteria from one surface to another across the kitchen. When that happens alongside biofilm buildup on utensils and inadequate ventilation, the facility's basic sanitation systems are not functioning as a defense. They become a liability.
The Longer Record
The August 11 inspection was not a departure from the norm at Khob Khun Thai Sushi. It was the norm.
State records show 29 inspections on file for this location, with 342 total violations accumulated across that history. The restaurant has logged high-severity violations in every inspection recorded in the prior two years. In October 2024, inspectors cited 10 high-severity violations in a single visit. The following March, inspectors returned and found 8 high-severity violations. In November 2025, the count was 9. In March 2026, it was 7.
The facility was emergency-closed once before, on the same day as the August 11 inspection, for rodent, roach, and fly activity. That closure lasted less than 24 hours. The follow-up inspection on August 12 found 1 high-severity and 2 intermediate violations, meaning high-priority problems persisted even after the reopening.
No inspection in recent memory produced a clean bill of health. The pattern across eight consecutive inspection cycles is a facility that routinely operates with multiple high-severity violations, addresses enough to reopen when closed, and returns to the same condition.
Still Open
State inspectors documented six high-severity violations at Khob Khun Thai Sushi on August 11, 2026, including food from an unapproved source, food not cooked to required temperatures, and toxic chemicals stored improperly. The restaurant was closed that day for pest activity and allowed to reopen the next morning.
The six high-severity violations from the August 11 inspection were not the basis for an emergency closure order.
The restaurant remained open.
