This analysis uses data on “animal production workers” from the 2022 American Community Survey to examine characteristics of workers who may be at risk for exposure to H5N1 avian influenza, which has been found in dairy cattle herds in nine U.S. states as of May 14, 2024. The analysis compares characteristics of these workers to all U.S. workers, to all workers in the H5N1-affected states, and draws out some implications. Among the findings are that animal production workers are more likely than workers overall to be Hispanic and noncitizen immigrants, as well as to be uninsured.
