I found an article claiming that the USDA had confirmed 41 more cases in 
California since the last update on the 24th making the total 178.

More poultry flocks are going down with the dairy virus in California 
and also in Oregon.  Washington and Oregon have not reported infected 
dairy herds, but in all other cases the poultry have been infected by 
proximity and likely shared workers from infected dairies.  They need to 
start looking for infected herds in Washington and Oregon if they want 
to try to stop the spread to humans on the West coast.

This article also has the disconcerting news of a human isolate.  It was 
a Texas isolate from virus cultured from the eye swab of the patient. 
It reportedly had the mutation associated with mammal infections, and 
was found to be lethal to other mammals and readily transmissible 
between animals.  The study was published in Nature.  It is evidence 
that the dairy virus is, and was from the beginning (the Texas patient 
was the first known human infected) a potential pandemic virus that 
should not have been allowed to propagate for as long as it has.

I saw a quote in another news article from a California dairy industry 
consultant that he thought that they would find 500 infected dairies in 
California by the end of November.  This was after the USDA stepped in 
to assist the contact tracing program with additional personnel. There 
are only 1,300 dairies in California.  The article also included the 
claim that the milk supply in California was being affected with 10 to 
15% mortality among affected, and reduced milk production of the 
survivors.  Some dairies with over 50% infected cows have their milk 
production severely affected, and it will take some time to bring the 
cows back into production and replace the mortality.  These dairies are 
huge.  The dairy with two infected workers had over 5,000 cows and 
another, with dairy workers in common, had over 7,000.  There are over 
1.7 million dairy cows in California.  The worst of it is that the virus 
has been constantly infecting and mutating in all the other states that 
have been infected.  There has been no attempt to identify all the 
infected herds, stop the spread to other dairy farms, and make sure that 
the workers are protected from infection.  Currently workers are not 
being protected at all the dairies that have not yet been identified as 
being infected.  California indicates that the number of unreported 
infected herds is substantial.
