CEDAR RAPIDS, Iowa (AP) — A second person who works within the Black Hawk County Jail in north-central Iowa has tested positive for COVID-19, officials there said.

An employee of Summit Food Services, the company that prepares meals for inmates, has been infected with the virus, according to a news release Wednesday from the Black Hawk County Sheriff’s Office.

Sheriff’s Capt. Nathan Neff said the kitchen staff has limited contact with jail staff and no contact with inmates.

Earlier in the week, the jail announced that a nurse who works the overnight shift at the jail had also tested positive. Officials said the nurse had very little contact with staff and inmates.
