SUPERMARKET giant Sainsbury's has apologised after wrongly labelling some of its Scottish salmon products.

The packaging said the smoked fish being sold as part of the store's Taste the Difference range was sourced from sea water farms at locations around Skye, Lewis and Uist, when in fact it was farmed at in Loch Fyne, a sea loch on the Argyll mainland. Sainsbury's previously issued an apology in May over the labelling, but issued a second apology as it emerged the product was still being sold with wrong labels in England.

The problem emerged after complaints by the Salmon and Trout Association Scotland, who allege that Loch Fyne is polluted with unacceptable levels of sea-lice, chemicals, faeces and diseases.

The Association raised the issue with the Advertising Standards Authority and Trading Standards in May.

At the time the supermarket apologised and admitted "an error" had occurred in its packaging due to a recent change in supplier and apologised to customers.

Association chairman Hughie Campbell-Adamson said the latest blunder was an "almost unbelievable state of affairs".

A statement from Sainsbury's said: "We would never seek to mislead our customers and would like to reassure them that this error has had no impact on our industry-leading sourcing standards."

The supermarket has also stated that its salmon is reared on RSPCA Freedom Food approved farms on the West Coast and Islands.
