evidence: Bird flu is affecting a growing number of cattle herds in the US, and these infections have led to only the second known human case in the nation, according to the US Centers for Disease Control and Prevention. [...] In total, seven herds have been affected by bird flu in Texas, two in Kansas, one in Michigan and one in New Mexico, the USDA said. It is also suspected in a herd in Idaho, but those test results are still being analyzed. Since the start of this outbreak of bird flu in January 2022, more than 82 million poultry in 48 states have been affected, according to the CDC. Cases were also detected in 9,253 wild birds, although the true number is probably much higher.
