The crisis in Ukraine could spill over into US supermarkets and the dining tables at one of the nation's largest seafood restaurant chains.

Russia's invasion of Ukraine last week has led to swift global backlash and a range of economic sanctions against the country and its leaders.

There is growing concern sanctions could extend to cover the nation's seafood exports, a move that would have a jarring effect on pollock and other whitefish supply chains.

Since the invasion, several US seafood associations, lawmakers and lobbyists are joining global leaders in condemning Russia's invasion of Ukraine, and are voicing their support for a ban on Russian seafood imports into the United States.
