H5N1 Infects 1,166 U.S. Dairy Herds Across 19 States as Idaho Leads With 173

Summary
USDA confirmed more than 1,166 H5N1-infected dairy herds in 19 states by July 22, with Idaho now the most affected active state at 173 herds.
Idaho logged nine new herd infections in the past 30 days, while Utah added 13 cases and Texas two, as officials say spread is being driven mainly by cattle-to-cattle contact via shared workers and equipment.
FDA and CDC still assess the broader public risk as low: pasteurized milk remains safe, no human-to-human transmission has been detected, and human cases have been limited to people directly exposed to infected animals.
Raw milk from infected cows can carry active virus, leaving dairy workers, veterinarians and nearby poultry operations at highest risk while vaccine candidates for cattle remain in field trials.
