The Arizona Republic reports that four state prison inmates were hospitalized with suspected botulism poisoning Friday after apparently drinking homemade prison alcohol, authorities said.

This is not the first time that prison inmates have been diagnosed with botulism following what is suspected to be an attempt at making homemade alcohol.

In 2011, 12 inmates at the Utah State Prison in Draper developed botulism after drinking a concoction made from fruit, potatoes, bread, water and sugar.

In 2004, four California inmates were hospitalized after contracting botulism from a two-gallon batch of prison-made alcohol.
