Tyson is ramping up its response to workers contracting coronavirus and is trying out advanced testing capabilities and enhanced on-site health care at plants including the Portland facility.

Coronavirus has infected workers at 115 meat and poultry processing plants in 19 states, according to a recent Centers for Disease Control and Prevention report. More than 4,900 workers contracted the virus, and at least 20 have died.

"Our top priority is the health and safety of our team members, and we are working with local health departments to manage the impact of this pandemic on our team members, their families and our communities," Tom Brower, Senior Vice President of Health and Safety for Tyson Foods, said in a statement.
