Waitrose has become the latest UK retailer to tell branded canned tuna products, that if they don’t stop using destructive methods to catch their tuna by the end of 2017, they will take their tin off their shelves.

The decision will add pressure on tuna companies, to begin catching tuna with the pole and line method, like all Waitrose branded canned tuna has been doing for eight years.

“When they buy a can of own-label tuna, our customers know that they are always buying a product which has been sustainably sourced – and now they will have the same assurance when it comes to buying a branded product,” said Jeremy Ryland Langley, aquaculture and fisheries manager at Waitrose.

Waitrose has become the first supermarket to set a deadline from the agreement which is a result of discussions over the past year to ensure that all the branded canned tuna sold will either be sourced using sustainable fishing methods or MSC certified.

Greenpeace are specifically targeting John West’s tuna, mentioning it came last in their 2015 tuna league table showing that more than 98% of its tuna is caught using destructive methods.

“Enough is enough. It’s time for John West to clean up or ship out. For too long they’ve only paid lip-service to sustainability – and now the games up,” said Hélène Bourges, oceans campaigner at Greenpeace UK.
