WASHINGTON (AFP) - The United States added farm-raised fish and shrimp to a growing list of Chinese products deemed unsafe for US consumers, regulators said Thursday.

The US Food and Drug Administration said it would block the import of farmed Chinese seafood until importers could prove the shipments were free of unsafe contaminants.

The move comes just days after lawmakers urged a recall of up to 450,000 Chinese tires because of safety defects and weeks after thousands of cats and dogs died because of tainted Chinese pet food.
