Associated Press: The first confirmed coronavirus outbreak at an Iowa meatpacking plant was far more severe than previously known, with more than twice as many workers becoming infected than the state Department of Public Health told the public, newly released records show. The department announced at a May 5 news conference that 221 employees at the Tyson Foods pork processing plant in Columbus Junction had tested positive for COVID-19. But days earlier, Tyson officials told Iowa workplace safety regulators during an inspection that 522 plant employees had been infected to their knowledge, documents obtained through the open records law show.
