June 27, 2018 — Greenpeace Japan is highlighting the prevalence of illegally-sourced eel in Japan’s supply chain and is calling for more traceability in advance of the midsummer day of the ox, a holiday celebrated by eating grilled eel. This year it falls on two days: 20 July and 1 August.
Greenpeace issued a report on 4 June that shows eels are at high risk from poaching and illegal transactions. The organization conducted a survey on eel procurement at major supermarkets, and found it was rare for the label attached to the grilled eel package to describe what kind of eel it is.
While there are four eels used for grilled eel – Japanese eel, European eel, American eel and bicolor eel – because grilled eel is a processed item, writing only “eel” is no problem in terms of rules. Although in 2013 the Fisheries Agency requested voluntary labeling of Japanese eel, few supermarkets do so. Akiko Tsuchiya of Greenpeace Japan said retailers should be required to label what species is contained in all boxes of grilled eel.
For its report, Greenpeace bought eel at the 18 shops and had an external DNA laboratory conduct genetic testing. The organization said the most confusion was between Japanese and American eel. The tests found one product labeled as grilled Japanese eel was actually American eel. Greenpeace said that it is proof that the supply chain from the glass eels to the shop is wrapped in darkness.
