Some of Britain’s leading supermarkets are facing questions about the salmon they sell after it emerged that the Scottish farms in their supply chain are “riddled” with sea lice.
Tesco, Sainsbury’s and Co-op promised to accelerate “the widespread adoption of effective sea lice controls” after data, published for the first time, showed levels up to 20 times the recommended limit on farmed fish.
Salmon farms are expected to keep average sea lice numbers below a “good practice” threshold of no more than one per farmed fish. Data obtained by Salmon & Trout Conservation Scotland (S&TCS), covering November 2016 to last August, names farms that reported average levels of at least three lice per farmed fish, and the number of weeks the breach lasted.
