JACKSON, MI – Maggots were found inside a Jackson prison for the second time in less than a week, but this time they were in the food.

Inmates on kitchen-duty at the Charles Egeler Reception & Guidance Center in Jackson were peeling potatoes early Tuesday, July 1, to be served that day, when they noticed maggots had taken up residency in the potatoes, said Michigan Department of Corrections Spokesman Russ Marlan. The potatoes are stored in bags in a dry-storage area.

On Friday, June 27, maggots were found just inches from the food service line at Parnall Correctional Facility in Jackson. Thirty prisoners are being treated for food poisoning-like symptoms, although it is unknown if the illness is related to the maggots.

The potatoes were not served Tuesday, and when Warden Heidi Washington was alerted to the incident she immediately had all of the potatoes removed from the kitchen, Marlan said.

"She ordered the kitchen to be cleaned with bleach," he said.

This is the latest in a string of reported issues with Aramark Correctional Services, the private vendor that the MDOC put on notice earlier this month due to unapproved menu changes and food shortages.

"The governor has made it very clear, that this is a very significant sanitary issue," Marlan said adding that Aramark officials are investigating the cause. "Every contract violation will be held against them."
