Maggots have been found at another state prison serviced by private food vendor, Aramark Correctional Services.
Department of Corrections officials say maggots were discovered in raw potatoes at the G. Robert Cotton Correctional Facility in Jackson on Tuesday.
Last year, maggots were found in food at three state prisons served by Aramark.
The Philadelphia-based food vendor was fined $200,000 last year for several violations of its $145 million contract with the state.
