The hunger strike at the James V. Allred Unit started Christmas day when 48 inmates refused to take meals in protest of various issues.
That number dropped to 37 by Tuesday, according to a Department of Criminal Justice spokesperson.
Robert Hurst with the TDCJ says all the inmates involved in the hunger strike were in administrative segregation, he said the issues the inmates raised vary from recreational time to food portions to temperature.
Although inmates were refusing to take meals, Hurst says most had items purchased in the prison commissary in their cells.
The TDCJ says administration segregation is a non-punitive measure to separate offenders from the general population for safety and security reasons.
Inmates in that category could include inmates judged to be escape risks, who pose a threat to other inmates or staff, or who have repeat disciplinary violations.
