Poultry workers test positive for TB
131 at Greenville plant show signs of exposure after active case found
State health officials tested 286 employees at a Greenville poultry-processing plant for tuberculosis after a case of TB was reported there, and nearly half had a positive skin test.
The investigation at Columbia Farms began a week ago after tests on the first individual confirmed active TB, said Thom Berry, spokesman for the state Department of Health and Environmental Control.
The positive skin tests on 131 of the workers means they were exposed to TB sometime in their lives, not that they have active disease, he said.
