The chef says, "Oysters are basically food poisoning gacha" is the intent of posting theory.

Oysters are basically "food poisoning gacha".Such tweets, a Twitter user who claims to be a chef in Osaka city, have a response of 24,000 "retweets".

What does this tweet mean?J-CAST News reported to users the intention of posting, and asked the stakeholders who were familiar with oysters.

"It has a certain probability"

In February 2018, 36 tourists who ate all -you -can -eat grilled kids at restaurants in Toba City, Mie Prefecture complained of symptoms such as diarrhea and vomiting.Mie Prefecture has been determined that it is a collective food poisoning by norovirus, and has been banned on business on the same date.All of them are eating grilled kids, oysters, oysters, etc., and the causative foods are being investigated.

Following this incident, Tatsu, a chef who is working on a wide range of genres in Japanese, Western and Chinese at a hotel in Osaka, posted on Twitter on February 19, saying, "A word as a chef."Moreover

「どんなに徹底管理、検査しても、新鮮でも、加熱しても、一切関係なくカキとは常に『一定の確率であたる』食べ物なので食べるときは自己責任で。多少体調にも左右されますが、基本的には食中毒ガチャです」

And developed the opinion.In the past, he worked at a lunch site (employee cafeteria) known for severe hygiene management.

"There is no zero risk in food"

In the first place, what is the possibility of a "hitting" oyster?Tatsu -san posted on Twitter that "if heated, norovirus is almost OK."In interviews with J-CAST News, the cause of the "hit" that cannot be prevented by heating is revealed as follows.

「貝毒（プランクトンの摂取で体内に毒素を蓄積させる現象）」「無自覚の牡蠣アレルギー」「亜鉛の過剰摂取による体調不良」「ノロウイルス二次感染（調理器具からの感染）」...

He also argued, "Even if it is safe oysters, it is not possible to deny food poisoning depending on the sanitary management of the store. There are some examples of being depressed by people."

In fact, the Ministry of Agriculture, Forestry and Fisheries, the Livestock Safety Management Division and the Fisheries Safety Office, also commented, "Bacterial food poisoning can be almost prevented by heating, but secondary infection cannot be denied."

"There are people on norovirus, infection after heating from raw oysters next to the cook, and capacity that can withstand the virus personally is different....He explained the possibility of a secondary infection.

On the other hand, the Ministry of Health, Labor and Welfare's Food Safety Planning Division said, "Because it depends on the situation, this is not the case. There is no zero risk in food."

What is "stricter than national standards"...

I want to deliver a safe oyster to consumers.The wholesalers have set a framework that exceeds the national regulation standards.

At the Japan Kaki Center (Chuo -ku, Tokyo), a wholly owned subsidiary of Japan's largest oyster bar chain "General Oyster" (Chuo -ku, Tokyo), a new oyster purification center was established in Irizen -cho, Toyama Prefecture.。For the first time in the world, we have built a system to purify with deep ocean water.

A person in charge of the center said, "We set up our own security and security standards, which are stricter than national standards. Purification with deep ocean water will not kill oyster nutrients."

"It may be said badly only on the store side"

Regarding the reason for posting tweets, Tatsu explained, "I felt that" all -you -can -eat oysters "entered the Twitter trend, and I felt that I couldn't do my profession."Moreover,

「ノロウイルスのみならず食中毒全般に対し、飲食業界は徹底した衛生管理や温度管理で対策を取っていますが、絶対はありません。そもそも無菌状態の食品など存在しません」

I emphasized.

「客の体調などを考慮せず、店舗側のみ悪く言われることもあります。少しでも『それは違う』と伝えられれば」

Finally, he told me what to be aware of when eating oysters.
