Research conducted by Greenpeace has found that the labels found on canned tuna, are often inaccurate.
The environmental watchdog analysed a sample of 50 brands and found that 30 per cent of the tins tested were mislabelled or had other irregularities. Some of the brands were found to contain different species of tuna across the same product, with some samples containing two different species of the fish in the same tin which is illegal in Europe.
Tests were carried out on canned tuna products from Europe, North America, New Zealand and Australia, with researchers testing a minimum of five different tuna brands from each country. The report findings were timed to coincide with the annual meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) which will take place in Paris on Saturday.
Most of the product labels found on canned tuna mention nutrition, dolphin safety and sustainability concerns. There is no mention of the mixing of species or the inclusion of under sized tuna from over-fished stock, which Greenpeace says is mainly due to the use of fish aggregation devices (FADS).
Greenpeace International oceans campaigner Nina Thuellen told the AFP: "Tuna companies are indiscriminately stuffing multiple species of tuna, including juveniles of species in decline, into tins that shoppers rightfully expect to contain a sustainable product. Retailers must act now to immediately shift their businesses away from cheap tuna caught using FADS."
