California Dairy herds positive for the dairy virus

3 herds in California central valley have been found to be positive for the dairy virus.

They claim that California workers are "usually" dedicated to just one herd so do not pick up shifts at nearby poultry farms, but months ago (before I retired in May) I noted that California had high levels of influenza virus in the waste water around the bay area.  At that time they had estimated that the virus first infected cattle Sept or Oct 2023, and they hadn't yet found viral sequence from herds infected that early in Texas.  When I looked into the avian influenza cases the Dairy virus was most similar to one isolated from a Peregrine falcon in California.  California had high levels of influenza virus in their waste water (associated with infected herds in Texas and Michigan) and Commercial poultry farms started to go down in the central valley in Oct 2023 (the flocks get infected by the dairy workers).  A number of flocks went down within a few months working their way up North and around the bay area.
I contacted a person at the Avian disease ARS station in Georgia, and tried to get the name of the person that would have the sequence data of the California samples (they had not been included in any of the dairy virus studies) but I was told that the USDA did not give out that information.  I told the guy that they needed to check out those samples, but his comment was that they were busy.
My prediction is that when they sequence the central valley virus they could identify the region where the initial dairy infection occurred and it spread from California to Texas.  The virus spread rapidly out of Texas, but it probably came from somewhere else.
The CDC and USDA would have identified many more states with infected herds by now if they had acted on the waste water data and the FDA identification of states with virus positive dairy products.  The Dairy workers are not being protected from being infected in states that refuse to identify their infected herds.
