Health officials say skin tests show that a total of 12 out of 318 people had been exposed to TB at some point in their lives.
This means they do not have active tuberculosis or are at risk of spreading the disease.
The South Health District began screening jail inmates and staff for TB in August and October, after a prisoner who passed through the jail tested positive for tuberculosis.
Though routinely, after a prisoner is housed at the Lowndes County jail for two weeks, the prison automatically tests that person for tuberculosis.
Officials say no one at the jail has active TB that could spread to other prisoners and staff members.
