It’s become fashionable for activist groups to demand that grocers provide ever-more information about the foods they sell. (“Group wants Albertsons’ notice about danger of fish to be more prominent,” June 21) But the recent campaign to force Albertsons to post mercury warnings in its stores is a case of food-fears run amok.

The vast majority of fish sold in America have mercury levels below the FDA’s “Action Level” — a mercury consumption guideline with a built-in 1,000 percent safety factor. For the few fish that exceed this FDA standard, consumers are still protected by a huge cushion. In 14 years of testing, the FDA has yet to find a single fish that would actually pose a health risk.

Men and women alike should be eating more fish, not less. It’s a low-fat food rich in nutrients. Warning signs like the ones these activists want would scare people away from a health food, even though the threat posed by mercury in fish is virtually non-existent.
