A last minute change to the US’s country of origin labelling laws has angered the Alaskan salmon industry.

The legislation was designed to help consumers identify the origin of products and, in the case of salmon, whether it was wild or farmed. But it now looks likely to allow the sale of salmon without the need for identification.

EU legislation does not require packers to say whether salmon is farmed, although a move in this direction would be welcomed by many.

“Most of the product sold under leading brands is wild, originating in either Alaska or Canada,” one importer said.
