VERO BEACH, FL. State inspectors visiting Oniku Hibachi at 4125 9th Street SW on August 26 found the restaurant operating without an approved potable water supply, a violation that means every dish washed, every surface rinsed, and every hand cleaned that day may have been done with water that could carry E. coli, Cryptosporidium, or Legionella.
The restaurant was not closed.
What Inspectors Found
The August 26 inspection documented 10 high-severity violations and 5 intermediate violations in a single visit. Among the high-severity findings: toxic chemicals stored improperly or without labels near food, food contact surfaces not properly cleaned or sanitized, and no allergen awareness demonstrated by staff.
Inspectors also cited the restaurant for improper hand and arm washing technique, no written employee health policy, inadequate shell stock identification records, and time as a public health control not properly used. A consumer advisory for raw or undercooked foods was absent from the menu. No person in charge was present or performing duties at the time of the inspection.
On the intermediate side, inspectors found improper sewage or wastewater disposal, multi-use utensils not properly cleaned, improper sanitizing solution or procedures, single-use items being reused, and inadequate ventilation and lighting.
The restaurant remained open after the inspection.
What These Violations Mean
The absence of an approved potable water supply is not a paperwork problem. Water used to rinse produce, clean cutting surfaces, and wash hands carries the same contamination risk as the food itself. Non-potable water can harbor E. coli, Cryptosporidium, and Giardia, pathogens that cause illness ranging from severe gastrointestinal distress to life-threatening infection in immunocompromised individuals.
The improper storage of toxic chemicals near food is a separate and acute hazard. Unlabeled or misplaced cleaning agents can contaminate food directly, and mislabeled containers have caused poisoning incidents in commercial kitchens when staff mistake a chemical for a food-safe product.
No allergen awareness at Oniku Hibachi means staff could not reliably identify which dishes contain common allergens, a gap that puts the 32 million Americans with food allergies at direct risk. Allergic reactions to undisclosed ingredients send roughly 30,000 people to emergency rooms each year. Combined with no consumer advisory for raw or undercooked foods, customers with compromised immune systems, pregnant women, and the elderly had no warning about the risks on the menu.
The absence of a written employee health policy removes the only formal mechanism that keeps sick workers out of the kitchen. Norovirus, which causes approximately 20 million illnesses in the United States each year, spreads with particular efficiency in food service settings when an infected employee handles food without restriction.
The Longer Record
The August 26 inspection was not an anomaly. State records show Oniku Hibachi has accumulated 246 violations across 22 inspections on record, a pace that works out to more than 11 violations per visit on average.
The pattern going back two years is consistent. Inspectors found 9 high-severity violations in December 2024, 8 high-severity violations in both July 2025 and January 2026, and 6 high-severity violations in July 2024. The restaurant has not had a clean inspection in any of the eight most recent visits on record.
The facility was emergency-closed on August 26 of this year for roach activity, the same date as the 10-violation inspection. It reopened the following day, August 27, after a callback inspection that found 1 high-severity and 1 intermediate violation still on the books.
That prior closure matters as context. A restaurant that has been shut down for active pest activity, reopened within 24 hours, and then logged 10 high-severity violations on the same calendar date is not in an isolated rough patch. The inspection history at Oniku Hibachi shows a facility that has been cycling through serious violations for at least two years without sustained improvement.
