For some reason they are putting out old information on infections that 
occurred before the dairy virus existed.  It is likely the H5N1 genotype 
B3.13 that eventually infected dairy cattle, but the birds and seals 
were infected in 2023 when the virus was still propagating mostly in 
wild birds.  The virus is not the same one that infected the recent 
Washington poultry flocks.  The poultry flocks were not infected by wild 
birds, but dairy cattle.  Early in the dairy infection in both Texas and 
Michigan it was determined that the infection was spreading herd to herd 
and from herd to poultry flocks, and that there was no evidence of a 
wild bird intermediate.  Basically all states that have infected cattle 
also started getting infected poultry flocks because it was found that 
some dairy workers also worked on other dairy farms and 7% of them also 
worked on poultry farms.

Washington should be testing their dairy herds because the dairy virus 
is spread herd to herd and then infects local poultry flocks.  It might 
be transmitted back to dairy herds from infected poultry workers, but 
flocks are rapidly depopulated, but herds are allowed to shed the virus 
and infect the human workers for months.
