Mercury and fish.  It’s been making headlines for months now, ever since the FDA warned pregnant women to severely limit their intake of fish and seafood.  But according to science writer Steven Milloy of FOXNews.com, the FDA’s fishy alarm is hardly seaworthy when it comes to the hard science.  For starters, Harvard’s School of Public Health could find no specific health complaints associated with higher levels of mercury, and even regular consumers of large species like swordfish had no mercury-related health effects.  Since no adverse effects were also found from pre- or post-natal exposure, it’s little wonder Milloy suggests the FDA clam up on these seafood warnings.
