Following a mass food poisoning outbreak in which 78 people reported feeling unwell after eating at an event that served crab ramen, chef Komeo announced on his X (Twitter) account on September 10 that he would introduce “monthly stool tests” and “health condition checks.” While framed as a measure to prevent a repeat of the incident, the announcement itself was met on 5channel with reactions like “So that means you weren’t doing that until now?” — sparking doubts about whether basic hygiene management had ever been in place at all. The thread also saw technical exchanges about whether stool testing is even legally required and where the bacteria behind the poisoning may have come from, going beyond simple criticism into more practical discussion.
Komeo introduces “monthly stool tests” and “health condition checks” after food poisoning incident — but questions erupt: “So that means you weren’t doing this before?”
After causing a mass food poisoning outbreak that left as many as 78 people feeling ill, chef Komeo declared he would “rebuild hygiene management from the ground up.” But that “fresh start” is already facing harsh scrutiny.
Updating his X account on September 10, Komeo wrote:
Honestly, forget the guy himself — I just want to know how the virus actually got in… Surely he wasn't cooking with hands that had, uh, poop on them, right?

Re: #3 It's naturally present in meat and fish that haven't been heated thoroughly enough. If you prep that on a cutting board and then cut vegetables with the same knife and board without sanitizing them, it transfers over — and if you don't apply enough heat after that, there you go.

Re: #15 Why are you cutting vegetables meant to be eaten raw with the same gear as the meat… that's way too reckless…

Re: #15 Salmonella isn't normally found in seafood.

You get served in a shoddier environment with worse food than people who just go out for an 800-yen bowl of ramen. Truly the "innovation" of a has-been country.

Hygiene management training is supposed to be mandatory, but I got through mine via something like a university stand-in course (not sure if that's still a thing these days).
10AnonymousSep 12, 2026 01:56
Managing ingredients, disinfecting, and checking your health condition should go without saying — but does everyone really do monthly stool tests these days?
11AnonymousSep 12, 2026 01:56
Simple solution: don't go to the place. Normally a restaurant would just go under after this.
12AnonymousSep 12, 2026 01:58
Got called out for leaving cardboard boxes on the floor, so now he's just put them up on a kitchen shelf instead lol
13AnonymousSep 12, 2026 01:58
There's no legal requirement for restaurants to do stool tests anyway.

Re: #13 It's not like he's a soapland worker (sex workers at Japanese "soapland" bathhouses are required to get regular health checks), so of course he wouldn't normally bother. This is the bad side of Japanese people — they don't do anything themselves but just assume everyone else is being diligent. They rebel against their school teachers, yet still assume those teachers were actually teaching them the right things.

Wouldn't washing your hands or just using clean gloves solve this?
16AnonymousSep 12, 2026 02:01
I'd think everyone who handles food already does that — if anything, isn't once a month overkill? Feels like he doesn't know even the most basic stuff that's common sense everywhere else.

Caused an incident so bad it should be career-ending, and he still thinks he can bounce back — total gangster mentality (反社, slang for shady, criminal-adjacent behavior). There's dumb, and then there's this.
21AnonymousSep 12, 2026 02:03
Here's a riddle: I'll compare a published book to this ramen. The connection? Simple — it just hasn't been found out yet!
22AnonymousSep 12, 2026 02:04
He hasn't reached the level where he should be serving food to other people, and he never will.
34AnonymousSep 12, 2026 02:11
Seriously, what shop did this guy even train at?
36AnonymousSep 12, 2026 02:13
Re: #34 A delinquent classmate of mine got a job at a sushi shop and bailed almost immediately — no way he could hack it. Mostly because they kick you there.
38AnonymousSep 12, 2026 02:14
From here on it's just karma catching up with him, so that's fine — but the problem is there's no law to actually crack down on this. If someone wanted to, they could pull off something like food terrorism easily, and the fact that you couldn't even charge them for it is scary.
40AnonymousSep 12, 2026 02:16
Re: #38 Nah, not terrorism — the payoff isn't worth the risk.
42AnonymousSep 12, 2026 02:18
No idiot is going to keep going there after this, right?
44AnonymousSep 12, 2026 02:21
Re: #42 You're a bit mistaken — this is exactly the kind of place idiots with nowhere else to go end up at.
46AnonymousSep 12, 2026 02:23
He never paid his dues. Someone who came up getting smacked around and yelled at by a master chef learns to recognize danger differently than he does.
49AnonymousSep 12, 2026 02:24
Re: #46 Because taking the contrarian route turns into a game of chicken over "look how many rules you can get away with breaking."
57AnonymousSep 12, 2026 02:36
Re: #55 Yeah, there isn't — legally speaking, anyway.
58AnonymousSep 12, 2026 02:46
Re: #57 You can pretty much tell, right — like "oh, this one's gonna give you the bad kind of diarrhea." Not to get political here (a stray reference to Japan's security-treaty debates), but you just know which stuff you shouldn't eat.
66AnonymousSep 12, 2026 03:06
Food safety is the first thing to get cut for cost savings.
67AnonymousSep 12, 2026 03:07
Re: #66 Don't assume that's free. I'll do it if you're paying for the stool test.
74AnonymousSep 12, 2026 03:22
If he wasn't doing stool tests, what was the health department even doing?
78AnonymousSep 12, 2026 03:25
Re: #74 Basically, the health department doesn't do anything — unless you actually cause a food poisoning outbreak.
80AnonymousSep 12, 2026 03:32
Re: #74 Hygiene management is something you're supposed to handle yourself in the first place.
Background and Talking Points
Stool testing for restaurants isn’t a legal requirement — it’s one of several forms of self-management businesses voluntarily carry out under the Food Sanitation Act. Health centers typically provide hygiene guidance during inspections, but they don’t monitor on a case-by-case basis whether stool tests are actually being performed. The thread split into two main currents: distrust over Komeo’s side offering too little explanation, and a more technical discussion about the bacteria responsible — the latter including corrections such as “Salmonella isn’t normally found in seafood,” meaning the discussion wasn’t purely emotional but also involved genuine exchanges of hygiene knowledge, a nuance the original article doesn’t fully capture. It’s also worth noting that whether “once a month” stool testing is high or low by industry standards isn’t something the forum posts alone can settle — readers who take away only the impression of “a restaurant that was doing nothing before” risk misreading the actual situation.
