A CDC report on bird flu shows potential transmission of bird flu between exposed dairy workers and indoor pet cats. The report also provides a window into the lack of reporting and cooperation at dairy farms and by dairy workers.

A new report details the bird flu cases of two pet cats in Michigan whose owners work in the dairy industry. Earlier in the month, a data table from the report may have appeared on the CDC website before being taken down.

But the study, whose publication was delayed by a pause in public communications by the agency, leaves key questions unanswered.
