Costco Agrees to Post Warning on mercury in Seafood

Costco Wholesale Corporation committed to warning its customers about mercury contamination in fish by posting the U.S. Food and Drug Administration (FDA) (link11) mercury warning on signs at seafood counters in all its stores. The move, prompted by requests from Oceana and Costco members, followed similar action by other major grocery chains nationwide. Thanks to Oceana’s campaign, more than 36 percent of major U.S. grocery stores now post the FDA warning.
