Map of cell area where inmates with diagnosed botulism resided during an outbreak in Arizona Prison A, November 24 to 26, 2012. The arrows indicate the passage of pruno contained in sealed plastic bags under cell doors, as reported by inmates in Prison A. This practice, known as “fishing,” uses walls to bounce pruno packages between cells and pods. The circle indicates drainage holes in the wall of the recreation area through which pruno was passed.
