Is there something fishy about the health advice on farmed salmon?

SMOKED salmon is the easy part of Christmas. Throw it on brown bread, with lemon and black pepper, and the innocents will think it’s posh and that you’ve spent a lot. 

But you can get 100g of Everyday Value smoked salmon in Tesco — “responsibly sourced from the waters around Scotland, Norway or Ireland” — for €3.59.

But, today, as many of us prepare for the big Christmas supermarket shop, the Friends of the Irish Environment have ramped up their boycott of farmed salmon, strengthened by the news that the international Slow Food Movement — which counts among its supporters Bridgestone’s Sally McKenna and that icon of Irish sustainable food, Darina Allen — has condemned intensive open-pen fish farms.
