On April 20, 2010, the Deepwater Horizon rig exploded in the Gulf of Mexico killing 11 crew members and leaking more than 200 million gallons of oil into the water. Today marks the one year anniversary of this disaster.

In the Louisiana marshes, members of the Pointe Aux Chenes Indian Tribe say the spill has affected everything.

"It changed our way of life for sure," says tribe member Theresa Dardar. "We're not eating like we usually eat."

She continues:

Her family used to eat seafood every day. Now, they eat shrimp only on Fridays. The rest of the week, it's chicken, pork and beans.

She says she hasn't had an oyster since "before the spill." That especially hurts because she longs for the oysters of the past.

"We love fresh oysters," she says. "My husband even more so. He was tempted to get some recently, but he said no, he wouldn't take a chance."

Dardar says the tribe had independent tests conducted on local shrimp, oysters and crab - and the results showed some were tainted.

"We don't trust the tests that the state and federal governments did."
