SAINT AUGUSTINE, FL. State inspectors walked into Corner Sushi on S US Highway 1 on June 18 and found food sourced from unapproved or unknown suppliers, a violation that means there is no way to trace that food back through the supply chain if a customer gets sick.
That was one of six high-severity violations documented at the Saint Augustine restaurant during the inspection. The facility was not closed.
What Inspectors Found
The unapproved food source violation stands out at a sushi restaurant, where raw fish is served directly to customers with no cooking step to kill pathogens. Food purchased outside the regulated supply chain has not been inspected by USDA or FDA, meaning there is no verification of how it was handled, stored, or transported before it arrived in the kitchen.
Inspectors also cited the restaurant for food contaminated by chemical, physical, or biological hazards. Combined with a separate violation for toxic chemicals improperly stored or labeled, the inspection record raises direct questions about whether cleaning or sanitizing products were kept near or above food preparation areas.
The cooking temperature violation adds another layer of risk. At a restaurant that also serves cooked items, food not brought to the required minimum temperature can leave Salmonella and other pathogens alive on the plate.
The restaurant had no consumer advisory posted for raw or undercooked foods. That advisory is specifically intended to warn elderly customers, pregnant women, young children, and anyone with a compromised immune system that consuming raw fish carries elevated risk. Without it, those customers have no way to make an informed decision.
What These Violations Mean
The unapproved food source violation is one of the most serious a food establishment can receive, and it carries particular weight at a sushi restaurant. When food enters a kitchen through unregulated channels, there is no documentation of where it came from, what temperatures it was held at during transit, or whether it was subject to any safety inspection. If a customer becomes ill after eating there, investigators have nowhere to start tracing the source.
The improper handwashing technique violation is frequently underestimated. An employee who goes through the motion of washing hands but does so incorrectly, such as skipping the friction step or rinsing too briefly, leaves pathogens on their hands. At a sushi counter where staff handle raw fish and then touch rice, seaweed, and plated food directly, that failure is a direct transmission route.
Improperly cleaned multi-use utensils and a compromised sanitizing solution compound the problem. Bacterial biofilms can form on utensil surfaces within 24 hours when cleaning is inadequate. Those biofilms are resistant to standard sanitizers, meaning that even a follow-up wipe-down may not eliminate what has already taken hold. At Corner Sushi, both the cleaning and the sanitizing steps were cited as deficient on the same inspection date.
Wiping cloths used incorrectly move contamination from one surface to another rather than removing it. When that failure occurs in the same kitchen where chemicals are improperly stored and utensils are not fully sanitized, the cumulative effect is a kitchen where multiple safeguards are failing at once.
The Longer Record
The June 18 inspection was not an aberration. State records show Corner Sushi has been inspected 26 times and has accumulated 199 total violations across its history. The restaurant has never been emergency-closed.
The most recent prior inspection, on December 5, 2025, produced five high-severity and two intermediate violations. Six months before that, on June 10, 2025, inspectors found six high-severity and one intermediate violation, a nearly identical profile to this month's inspection. The pattern of six or more high-severity violations appearing in a single inspection has now occurred at least three times in the past 13 months.
Going further back, the record is consistent. Inspectors cited seven high-severity violations in October 2023, nine in February 2023, and seven more in October 2022. The one exception in recent years was a June 2024 inspection that produced zero high or intermediate violations, a single clean result surrounded on both sides by inspections with four or more high-severity findings.
The facility has never triggered an emergency closure in 26 inspections on record.
Still Open
Florida's emergency closure authority is triggered when an inspector determines that conditions pose an immediate threat to public health. On June 18, Corner Sushi received citations for unapproved food sources, contaminated food, improper cooking temperatures, and toxic chemicals stored without proper labeling or placement.
The restaurant remained open after the inspection.
