New website provides Gulf seafood testing data to curb oil contaminate fears

“Now it will be easier for people outside of Louisiana to know what we already know — the seafood is safe and as good as ever,” said Louisiana Department of Environmental Quality Secretary Peggy Hatch.

 

But environmentalists say doubt remains about the validity of state testing.

“The bottom line is, should we really have oil and gas products in our seafood?” said Anne Rolfes, director of the New Orleans based Louisiana Bucket Brigade.

The website, Gulfsource.org, allows users to scroll through samples or search by area, data or sample type. It was created to show that state testing has found no levels of oil in water, sediment or seafood that are a danger to human health, officials said. Test results for dispersants are also available.

Louisiana received $18 million from BP after the oil spill to pay for seafood, water and sediment testing over three years. Officials test for chemicals called polycyclic aromatic hydrocarbons, or PAHs, oil toxins known to cause cancer and other health effects. They also test for dispersant chemicals called dioctyl sodium sulfosuccinate. So far, none of the more than 2,100 samples have found either type of chemical at a level dangerous to human health, state and federal officials say.

Tests are conducted in waters across the state, taking 143 crabs, fish, shrimp and oysters and 96 sediment and water samples each month for testing. The testing is done by the state departments of Wildlife and Fisheries, Health and Hospitals, Environmental Quality and Agriculture and Forestry.

“Though we've been testing seafood, water and sediment since April 30, 2010, in response to the BP oil spill, the information has been difficult to widely distribute to the public,” said Wildlife and Fisheries Secretary Robert Barham. “We hope the public will utilize GulfSource.org to find out what the safety test results in seafood from areas they fish or from waters they consume reveal. Rebuilding our seafood brand starts with rebuilding consumer confidence in our product.”

Through the website's front page, you can scroll through a timeline of samples taken between May 16, 2010, and Friday.

Samples laid out on the website show:

A Google map of where they were taken and a list of oil-related chemicals officials tested for.

What was found in each sample.

What the “level of concern,” the level considered harmful to human health, is for each chemical.

You can also search the data by the time samples were taken, where they were taken, and by species and sample type. Those search results return a less user-friendly data table listing the date of samples, whether oil chemicals were above detectable limits and the location's coordinates. The data are available for download with the “export” buttons at the bottom of the page.

Rolfes said issues have been raised with the sensitivity of oil tests. There are also questions about whether the standard the government is using for determining whether chemicals pose a harm to human health is set too high.

Recent studies by scientists at LSU have shown that even if low levels of oil don't pose a harm to human health, even the tiniest amounts of oil can have serious impacts on fish.

Studying killifish, an abundant marsh fish, scientists found damage to gills and genetic changes that indicate future reproductive and developmental problems related to oil.

“Why are we saying it's OK, it's an acceptable level of oil and gas?' ” Rolfes said.
