There's always the first. Or I should say the first to get caught.
But before finally busted, the meat dealer already sold 1,424 kilograms of beef from Tohoku and northern Kanto, including 750 kilograms of beef from Fukushima.
From Yomiuri Shinbun (4/13/2012):
A dealer falsified Fukushima beef as "made in Kagoshima", as it is difficult to sell if labeled "made in Fukushima"
The Kinki Regional Agricultural Administration Office of the Ministry of Agriculture, Forestry and Fisheries directed the meat dealer "AMMS" (Itami City in Hyogo Prefecture) to improve labeling based on the JAS (Japanese Agricultural Standard) on April 13.
According to the Ministry, the dealer says [they falsified the origin because] it was difficult to sell with labels saying "made in Fukushima" and other prefectures. This is the first time since the start of the Fukushima I Nuclear Power Plant accident that the beef from Fukushima was deliberately mislabeled.
According to the press release, the dealer's store 福田屋此花店 in Osaka City sold at least 1,424 kilograms of beef from Tohoku and Kanto regions as "made in Kagoshima" and other prefectures, including 750 kilograms of beef from Fukushima. The Ministry conducted a site check on an anonymous tip.
Almost all of the beef had been already consumed, but according to the Ministry it was not on the list by the Ministry of Health of beef from the cattle that ate rice hay contaminated with radioactive cesium last year. None of the beef has been found with radioactive cesium exceeding the national safety standard.
No penalty from the supervising Ministry, though, other than "directing the dealer to display proper labels". The press release from the Kinki Regional Agricultural Administration Office on April 13, 2012 basically tells the dealer:
Please find out why this happened;
Please label appropriately from now on;
Please set up a system so that this won't happen again;
Please educate your employees appropriately from now on;
Please send us the report of your finding by May 14, 2012.
Why did this happen? Isn't that obvious? The dealer made a killing by buying up beef from Tohoku and Kanto at a depressed price, labeled it as "made in Kagoshima" and sold it at probably a huge premium.
The Kinki Agricultural Admin Office also says the dealer sold 280 kilograms of beef from Miyagi. No further information on the beef that this dealer sold that was of Kanto origin. Probably northern Kanto - Tochigi, Gunma, Ibaraki.
