(A-P) – A new report studying the impact of the coronavirus on workers in meat processing plants has found that 87% of people infected were racial or ethnic minorities and that at least 86 workers have died. The report released Tuesday by the U.S. Centers for Disease Control and Prevention examined more than 16,000 COVID-19 cases at 239 plants in 21 states.

It offers perspective on how the virus devastated U.S. pork, beef and poultry processing plants, but the figures likely understate the problem as Iowa officials declined to participate in the study. The data shows 56% of coronavirus illnesses involved Hispanic workers, 19% were non-Hispanic Blacks and 12% were Asian.
