Sept. 29, 2005 — Fish samples collected from coastal and offshore marine waters of the Gulf of Mexico two weeks after Hurricane Katrina show no elevated exposure to contaminants related to oil, announced NOAA. These results are just one part of contaminant testing of Gulf water and fish currently underway at NOAA. Additional results on potential exposure to bacteria, pesticides and other toxic chemicals will be available within days, and additional testing on shrimp samples from Mississippi Sound is ongoing.
NOAA will continue to collect and test samples over the next two months to monitor for changes due to releases of contaminants and as water is once again pumped out of the streets of New Orleans after floods caused by Hurricane Rita.
"As people in the Gulf region begin to rebuild their lives and return to work, NOAA will continue to monitor the effects of the hurricanes on seafood and coastal water safety," said retired Navy Vice Adm. Conrad C. Lautenbacher Jr., under secretary of commerce for oceans and atmosphere and NOAA administrator. "Results from the first limited round of tests show that the water quality and fish in the Gulf of Mexico do not now indicate an elevated presence of hydrocarbons due to oil. We expect to have results from pesticide and chemical tests in the coming days."
NOAA's environmental impact research is part of a government-wide effort to keep the American people safe and to help stabilize the region's economy in the aftermath of the Gulf hurricanes. The area is known for its valuable seafood production and coastal way of life.
Agency scientists conducted the research cruise aboard the NOAA research vessel Nancy Foster September 13 to 16. The vessel sailed from Pensacola, Fla., along the coastlines of Alabama and Mississippi, and then around the southern tip of Louisiana at the mouth of the Mississippi River and back. During the cruise, oceanographers, toxicologists and microbiologists collected water, fish and sediment samples to determine whether Hurricane Katrina resulted in elevated levels of contaminants in the ocean.
"We will continue to monitor the environment and fish and shellfish to assure the public that the seafood supply is healthy," said Bill Hogarth, director of NOAA Fisheries Service.
The samples were flown to one of NOAA's premier toxicology labs in Seattle, Wash., as soon as the ship returned to port in Pensacola on Friday, Sept. 16. Last week, the samples were prepared and tested for a variety of chemical contaminants, such as polycyclic aromatic compounds, which are typically absorbed by marine life in areas impacted by oil spills. The samples also were tested for a number of harmful bacteria, and the results of those tests will be made available as soon as the analyses are complete.
NOAA also has contracted with the owner of the Patricia Jean, a commercial shrimp vessel, to collect samples from shallower waters of the Mississippi Sound and into Lake Pontchartrain. NOAA scientists aboard the Patricia Jean will continue to collect water, fish and sediment samples. Both the Patricia Jean and the Nancy Foster are in the Gulf of Mexico conducting follow-up surveys this week.
NOAA also is conducting a comprehensive analysis of fishing infrastructure damage caused by the hurricanes. The agency has teams surveying the region's fishing fleets, seafood processing plants, fish markets and bait shops. The survey will take months to complete, although NOAA will release preliminary information as it becomes available.
NOAA Fisheries Service is dedicated to protecting and preserving our nation's living marine resources and their habitats through scientific research, management and enforcement. NOAA Fisheries Service provides effective stewardship of these resources for the benefit of the nation, supporting coastal communities that depend upon them, and helping to provide safe and healthy seafood to consumers and recreational opportunities for the American public.
NOAA, an agency of the U.S. Department of Commerce, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and providing environmental stewardship of the nation's coastal and marine resources.
