H5N1 highly pathogenic avian influenza is entering its fourth year in the US and has been detected in poultry, dairy cattle, pigs and humans. Experts are concerned about spread to additional mammal species, and fall migration brought more wild bird detections in some states.
Bird flu has been found in cattle in California, Texas and Wisconsin in recent months.
Poultry losses and culls from bird flu tighten chicken supply and can lift poultry prices. Unpredictable cross-species spread adds to supply risk.
