NORTH MIAMI BEACH, FL. State inspectors visiting Mizumi Buffet and Sushi at 3207 NE 163rd Street on September 28 documented that the restaurant was serving food sourced from unapproved or unknown suppliers, a violation that means some portion of what customers ate that day had never passed through a USDA or FDA safety checkpoint.

That was one of six high-severity violations cited in a single visit. The restaurant was not closed.

8INTInadequate ventilation and lightingAir quality failure

The unapproved food source violation is particularly pointed at a sushi buffet. Fish served raw or undercooked requires verified sourcing and, in many cases, documented parasite-destruction freezing. Without a traceable supplier, there is no way to verify either.

The inspector also cited employees for not reporting illness symptoms, and separately for improper handwashing technique, and for having inadequate handwashing facilities in the first place. That is three compounding failures in the same hygiene chain: the sink setup is inadequate, the technique is wrong, and workers are not disclosing when they are sick.

Food contact surfaces were not properly cleaned or sanitized. The restaurant also carried no consumer advisory disclosing that raw or undercooked items were on the menu, a required notice that gives customers with compromised immune systems, elderly diners, pregnant women, and children the information they need to make an informed choice.

Two intermediate violations rounded out the inspection: single-use items were being reused, and ventilation and lighting were found inadequate.

What These Violations Mean

The unapproved food source citation is not a paperwork problem. When food bypasses the licensed supply chain, inspectors have no way to verify it was handled, stored, or transported safely before arriving at the restaurant. If someone gets sick, investigators cannot trace the product back to its origin. At a sushi buffet, where raw fish is a routine menu item, that traceability gap carries direct and immediate consequences.

The illness-reporting failure is the violation public health officials most closely associate with multi-victim outbreaks. A food worker with norovirus who does not report symptoms and is not sent home can infect dozens of customers before anyone connects the cases. The fact that this violation appeared alongside inadequate handwashing infrastructure and improper technique means the safeguards that might otherwise limit transmission were also absent.

Improperly cleaned food contact surfaces, the fifth high-severity violation, function as a transfer point. Bacteria from raw proteins survive on cutting boards, prep surfaces, and utensils, and move to ready-to-eat food when those surfaces are not sanitized between uses. At a buffet operating at volume, the exposure window is wide.

The missing consumer advisory for raw and undercooked foods is a legal requirement specifically designed to protect the diners least able to fight off a foodborne pathogen. Without it, a customer who is immunocompromised, elderly, or pregnant has no way of knowing that the food in front of them carries elevated risk.

The Longer Record

The September 28 inspection was not an anomaly. State records show Mizumi Buffet and Sushi has been inspected 31 times, accumulating 325 total violations across that history.

The pattern in recent visits is consistent. On March 25, 2026, inspectors cited six high-severity violations and two intermediate ones, an identical severity profile to the September 28 inspection. On June 24, 2025, the count reached seven high-severity violations and three intermediate ones. On October 22, 2025, it was five high-severity violations and one intermediate.

The cycle is visible in the data. A high-violation inspection is followed within days by a callback visit that shows improvement, sometimes a clean inspection, and then the violations return at the next routine visit. The September 28 inspection with six high-severity violations was followed by a September 30 visit showing four high-severity violations, and then an October 2 visit showing none. The restaurant has never been emergency-closed in 31 inspections on record.

Open for Business

State rules give inspectors discretion to emergency-close a facility when violations present an immediate threat to public health. Six high-severity violations at a sushi buffet, including food from an unverified source, employees not reporting illness, and unsanitized food contact surfaces, did not trigger that threshold on September 28.

Two days later, a follow-up inspection still found four high-severity violations.

The restaurant remained open throughout.
