Thousands of salmon products have been recalled from eight different supermarket chains because they may have been contaminated with diesel. The alert affects 50 types of Scottish salmon products including steaks, pies and fillets. The problem has been traced to the seafood company Marine Harvest which supplies fish to Morrisons and Young’s Seafood Ltd. The fish is thought to have been contaminated by diesel from a vehicle during transportation to a processing plant. The problem was detected when some customers complained of an unpleasant white spirit like taste. The alert does not affect organic salmon.
