Prison food is no picnic, what with the horse nuts (canned plums), dog food, Salmonella in eggs, and the rumored saltpeter.

The Arkansas Department of Health has confirmed the presence of Salmonella in chicken salad served at the Arkansas Department of Correction’s Tucker Unit on Aug. 4 that sickened hundreds of inmates with nausea and diarrhea.

Correction department spokeswoman Shea Wilson says footage from security cameras shows the chicken was cooked for three hours. But Wilson tells the Arkansas Democrat-Gazette that the chicken may have been left out for too long after it was cooked.

I didn’t know surveillance cameras could measure temperature. The chicken salad was prepared by inmates.
