Fugu blowfish fail sparks emergency warning in Japan city
Five packs of Yorito fugu (blunt head blowfish) were sold at a supermarket located in Gamagori city, in the central Aichi prefecture, by a licensed employee who had not removed the livers, according to Hiroko Mizuno, an official from the district's Life and Hygiene Department.
The fish, also referred to as puffer fish, contains a toxin hundreds of times more poisonous than cyanide; its liver alone can contain enough poison to kill five men. Japan has laws in place to ensure it is prepared and detoxified properly before it is sold.
Fugu, with its lethal innards, is considered a winter time delicacy in Japan, with high-end Tokyo restaurants charging customers 22,000 yen ($199 US) to risk death.
The two people who consumed the fish have not reported any health problems as this time. However, Gamagori city activated an emergency warning to its citizens alerting them through all wireless systems, including community loud speakers, against eating the fugu and recalling the product.
Mizuno told CNN that this particular type of blowfish usually has very weak or no poison, but the food hygiene laws prohibit the sale of any liver given its potentially poisonous implications. The liver should never be eaten because only testing can detect the poison.
Two packs of the recalled fish were located and returned on Monday night after
