Chemical dispersants in Gulf of Mexico not hurting seafood, FDA says

By Lyndsey Layton

Chemical dispersants sprayed into the Gulf of Mexico to break up the massive oil spill from the Deepwater Horizon disaster do not appear to threaten the safety of seafood in the affected waters, the Food and Drug Administration said this week.

In a letter sent in response to questions from Rep. Edward J. Markey (D-Mass.), the agency responsible for ensuring the safety of seafood said that chemicals used to break up the slicks are not as dangerous to human health as the oil itself.

FDA scientists do not think that the chemicals accumulate significantly in the tissue of fish and shellfish; even if fish absorb the chemicals through gills or other ways, the fish do not retain them, Jeanne Ireland, the FDA's assistant commissioner for legislation, wrote to Markey. That means the chemicals are not passed up the food chain to humans and are not considered a public health concern, according to the FDA.
