Meat Hope, a Hokkaido meat processor founded by Minoru Tanaka in 1976, systematically sold products under false labels, including ground beef marketed as 100% beef. Investigations found pork, chicken, innards, blood, bread scraps, flavoring agents, expired meat and returned products mixed into meat products. The company also allegedly relabeled imported Brazilian poultry as domestic, falsified salmonella data on sausages supplied to school-lunch firms, and used contaminated or spoiled meat in restructured products. According to a Ministry of Agriculture, Forestry and Fisheries investigation, 9,838 tons of ground beef were distributed between July 2006 and June 2007, including 5,504 tons to business customers.
Managing director Kiroku Akahane said he warned Tanaka and anonymously contacted local health officials, the Hokkaido agriculture office and national authorities. After resigning in April 2006, he publicly submitted allegations, although the MAFF and Hokkaido government disputed or lacked records confirming parts of his account. In spring 2007, Asahi Shimbun testing detected pork and chicken in beef croquettes, prompting police searches on June 24. Meat Hope filed for bankruptcy on July 17, 2007, with approximately ¥670 million in debt. Tanaka was arrested and sentenced by the Sapporo District Court on March 19, 2008, to four years in prison for violating Japan's Unfair Competition Prevention Law. The scandal intensified scrutiny of Japan's whistleblower protections and food-safety enforcement; the Consumer Affairs Agency opened on September 1, 2009.
