NOAA has announced that it is continuing to re-test seafood from the Gulf of Mexico, with re-testing scheduled to run into the summer.
Before waters were opened to fishing, NOAA and FDA performed extensive tests on seafood from those waters, and NOAA has now completed two additional rounds of sampling and testing from reopened areas. According to NOAA, thousands of test results have indicated that Gulf seafood is safe from oil and dispersant contamination.
In June 2010, NOAA, FDA and the Gulf states agreed upon an extensive sampling and testing procedure. Areas closed to fishing were reopened only when all seafood sampled in the area passed both the established sensory and chemical testing for oil and dispersants.
