The Centers for Disease Control and Prevention says fewer than half the states provided detailed data for a study of COVID-19 infections in meat plants—but the information they do have is disturbing.

The CDC says 87% of coronavirus infections in meat and poultry plants in the states that provided data were among minorities, especially Latino workers, who made up around 30% of the meat processing workforce but accounted for 56% of cases, the Hill reports.

With data from 23 states, the CDC said it had identified 17,358 cases of COVID-19, including 91 deaths, at 264 meat and poultry plants through May 31.
