Associated Press: Iowa regulators say they found no workplace safety violations at Tyson Foods’ largest pork processing plant, which employed several people who died after contracting the coronavirus. The Iowa Occupational Safety and Health Administration closed its inquiry into the Tyson plant in Waterloo earlier this month without sanctioning the meat company. County officials and workers have alleged that in March and part of April workers did not have adequate personal protective equipment to stop the spread of the virus and were not social distancing.
