They are claiming that sequence results indicate that the Arizona dairy
D1.1 infection is not related to the D1.1 dairy infection in Nevada.
This would mean that avian influenza has transferred to cattle 3
independent events. Texas (B3.13), Nevada (D1.1), and now Arizona (D1.1)

Two more cats in Oregon were infected by contaminated raw pet food made
in Washington state. They identified H5N1 in the cats that needed to be
put down, and the pet food that both cats had eaten (the same brand).
They now have a consumer alert on Wild Coast Raw, pet food. A bunch of
commercial and backyard poultry flocks have been hit by H5N1 in 4
states, but like the cats they aren't stating what genotype they were
infected with. Two large layer farms went down in Indiana. Over 57
million birds affected since just Nov. 2024, 162 million since 2022.

It should be noted that they only detected the Nevada and Arizona
infections due to the recent USDA testing program. The claim is that
the herds were not showing symptoms until after they turned out
positive. They would have never been tested under the old volunteer
testing program.

California is claiming that 281 of the 745 infected herds have cleared
the virus already. This likely means that the virus likely has infected
most of the herds in other states and they are likely fully recovered by
the time that the USDA is finally testing them. 9 states were
identified to have produced virus positive milk samples by the FDA, but
they would not test their dairy herds back in May 2024. 3 of those
states eventually claimed at least one infected herd, but the others
remained in denial. The virus likely burned through all the herds in
those states by now, and the herds would have recovered months ago. The
D1.1 dairy infections is the second wave for these states. Nevada had
an older case of dairy virus infection, but they only claimed one
infected herd, now they have half a dozen herds infected with D1.1, and
none detected with B3.13. The D1.1 virus likely spread through the
Nevada herds the same way that the B3.13 virus spread (cattle and people
shared between farms). Now we even have evidence (3 infected
veterinarians) that vets could have taken the virus from farm to farm,
and not even known that they were infected.

Avian flu now a major problem in Northern Ireland:

"About 64,000 birds are being culled in County Tyrone after suspected
avian flu was reported at a commercial poultry premises. https://www.bbc.com/news/articles/cvgm28zp82zo

"Northern Ireland in eight-week provincewide bird lockdown as battle
against avian flu outbreak continues." https://www.msn.com/en-gb/news/other/northern-ireland-in-eight-week-provincewide-bird-lockdown-as-battle-against-avian-flu-outbreak-continues/ar-AA1zdYBM

With a very large beef and dairy industry throughout Ireland, I'd
guess a lot of famers are very worried right now about this spreading
to cattle.

Avian flu has been an issue in Britain for a while. As I understand the
strains involved in Eurasia are different from those involved in North
America, and in the short term the threat to the Irish cattle industry
may be more from American tourists (or Irish tourists returning from
America) than from avian flu in domestic fowl or wild bird populations.

Worldwide avian flu has jumped to a number of mammal populations over
the years, often with substantial mortality. I reckon that the world
ought to be looking into veterinary vaccines.
