Costco posts mercury warning on seafood counters

WASHINGTON Costco has agreed to post the Food and Drug Administration mercury advice on signs at its seafood counters, ocean conservation group Oceana announced.

"Posting a sign that tells consumers which fish they should avoid would let them know that other fish are OK to eat, and allay any fears they may have," said Simon Mahan, campaign manager for Oceana.  "In fact, some grocery stores that posted the FDA advice had no negative effect on their seafood sales and one company even reported that seafood sales increased after posting the signs," he added.
