2013 Vieques Report

From 1999 through 2003, the Agency for Toxic Substances and Disease Registry (ATSDR) looked at whether U.S. Navy past military activity exposed Viequenses to harmful levels of chemicals. In 2009, we began updating our original findings. We evaluated data that we did not have in 2003.

ATSDR’s examination includes health protective recommendations, specifically for seafood consumption. Some Viequenses could be exposed to harmful levels of mercury from eating fish, if they frequently eat more than the recommended amounts. Pregnant women, women planning to become pregnant, and nursing mothers can eat up to 12 ounces of fish weekly. Children younger than age 7 can eat up to 4 ounces of fish weekly. ATSDR has recommended that public health officials consider conducting a fish consumption survey.
