According to the AP, the Pennsylvania Department of Health has confirmed a suspected outbreak of salmonella poisoning at a federal prison in northeastern Pennsylvania, that has reportedly sickened more than 500 inmates and guards.

The Health Department’s director of communications, Christine Cronkright, tells The Associated Press that most of those sickened at the U.S. Penitentiary-Canaan in Waymart reported eating chicken fajitas last month. Cronkright says a federal inspector is on his way to the facility, and that the prison’s food service facility has been shut down pending cleaning and inspection.

Here is the part of the story that should raise more than a few questions:

The AP first learned of the outbreak from attorneys at the Seattle-based law firm of Marler Clark, which specializes in foodborne illness litigation. Attorneys there say the families of more than a half dozen inmates called them this week to report the outbreak.
