Japanese city on alert for deadly fugu blowfish

A Japanese city has broadcast emergency warnings to
Prevent people consuming blowfish, after potentially
deadly portions were mistakenly sold.
A local supermarket in Gamagori city sold five packets of
fugu fish without removing the livers, which contain poison.
Three have been found but two remain missing.
The delicacy is so poisonous that the smallest mistake in
its preparation can be fatal.
Each year there are several cases of fugu poisoning in the
country, but not all are lethal.

The fish more poisonous than cyanide
City authorities in Gamagori, in central Japan, have
activated an emergency system, urging people to return
the potentially lethal portions.
"We are calling for residents to avoid eating fugu, using
Gamagori city's emergency wireless system," which
broadcasts over loudspeakers located around the city, local
official Koji Takayanagi told AFP.
Fugu, an expensive seasonal winter dish, is eaten raw as
sashimi or cooked in soup.
The fish's livers, ovaries and skin contain the deadly
poison tetrodotoxin and special training and a licence are
required to prepare the fish.
There is no antidote to the poison.
Tetrodotoxin affects the nerve system and the poisoning
has been described as "rapid and violent", leading to first a
numbness around the mouth, then paralysis and eventually
death.
