NEAL CONAN, HOST:

This is TALK OF THE NATION. I'm Neal Conan in Washington. We don't know much about Saturday's talks in Istanbul between Iran and the group of six major powers, but all sides used positive terms like constructive and agreed to a second round in Baghdad.

While diplomacy continues, the United States warns that the window for talks is closing. There's open talk of preemptive air strikes in Israel, and ever-tightening sanctions continue to squeeze Iran's economy.

The fact that there has been a salmonella outbreak among people who eat sushi isn't super surprising; raw seafood does pose more health risks than cooked fish.

But the fact that the fish implicated in the outbreak is something called "tuna scrape" sure got our attention here at The Salt.

According to the Food and Drug Administration's recall notice, tuna scrape is "tuna backmeat, which is specifically scraped off from the bones, and looks like a ground product." In other words, tuna hamburger.

The Justice Department and 41 Native American tribes recently announced a roughly $1 billion settlement. The agreement settles long-standing disputes over whether the federal government mismanaged tribal money and resources. Host Michel Martin speaks with Rob Capriccioso of Indian Country Today Media Network.

Charles and David Koch filed two lawsuits against the libertarian think tank that one of them helped found. The brothers say they want Cato to stay true to its 'principles.' But many in Cato say the move will put the brothers in charge and threatens Cato's independence. Cato's Michael Cannon speaks with host Michel Martin.
