Reports obtained by The Associated Press through records requests find numerous problems reported since April, when the state took the rare step of fining the vendor.
The records show 65 instances where employees of Philadelphia-based Aramark Correctional Services failed to provide food or ran out. They also show five cases of maggots found in food or the preparation process, and days when Aramark employees failed to come to work.
Aramark says it's the victim of an anti-privatization campaign and problems are declining.
Proponents say privatizing prison services saves money. Opponents say a focus on the bottom line leads to cutting corners that creates danger for inmates and employees.
