"Tyson Foods, one of the world’s largest food companies, has revealed the scale of the novel coronavirus outbreak at its poultry plant in Wilkesboro," Charlotte's WSOC-TV reports. "Facility-wide testing found that 570 people out of the plant’s 2,244-strong workforce were positive for covid-19, the majority of whom 'did not show any symptoms and otherwise would not have been identified,' the company said in a statement Wednesday."

Most of the workers were tested May 6-9; those who tested positive are receiving paid leave and will return to work only after they've recovered, according to a Tyson statement. The plant was shut down for several days for sanitizing, but production is beginning to ramp back up. Tyson is carrying out increased testing, safety measures, and on-site health care options at more than 30 of its plants, including the one in Wilkesboro, WSOC-TV reports.

Meatpacking plants have become major rural pandemic hotspots partly because of working conditions that workers, many of them undocumented immigrants, have little power to challenge.
