Today's briefing about the fish-testing program will take place at a tidy new NOAA building with ocean-colored accents in low-lying Pascagoula. After crossing several bridges arcing over the marsh, we were greeted by Monica Allen, deputy director of NOAA fisheries communications, who was friendly and crisp in her light blue NOAA shirt.

The new testers will have to focus, given the earthy smells being emitted by an adjacent waste treatment plant.

On hand for the briefing are representatives of six or seven media organizations, including the New York Times, Washington Post, AP Television and the New Orleans Times-Picayune.

We're now marching down to the dock for an initial look at an incoming seafood sample. More shortly.
