Indiana continues to have infections of their commercial poultry
farms. There is no information on how all the infections are
related. They have all occurred in a small number of counties.

26 more dairy herds are reported confirmed infections in June.-a 1
dairy in Utah and 25 more dairies in Idaho.-a The USDA is not
releasing the genotype, nor are they counting the reinfected herds
so the true extent of the epidemic is not known.-a Texas, Utah, and
Idaho had infected dairy herds in 2024.-a Texas and Utah had been
considered to be "unaffected" in May (6 months without bulk milk
tank positive) but Texas and Utah have obviously been reinfected
again.-a The only known affected state was Idaho, so it should not be >>>> hard to do the contact tracing to determine how the Texas and Utah
dairies got infected. There are 3 states whose status is unknown
because they do not participate in the bulk milk tank testing.-a So
the virus doesn't necessarily have to come from Idaho.-a One of the
three states is Florida that had positive waste water and produced
positive dairy products in 2024, but never tested dairy herds for
the virus.

Another commercial poultry farm infected in Indiana in the same
county as several others in late May.-a They likely need to do the
contact tracing and poultry worker testing, or keep the poultry
workers from working on more than one farm.
Ron Okimoto
6 more herds infected in Idaho and 1 more herd infected in Utah.-a The
USDA should give the number of reinfected herds so that the true
extent of the current epidemic can be evaluated.-a 53 total herds
newly infected in 2026 (Mostly in Idaho, but also in Texas and
Utah).-a 33 herds in the first couple of weeks in June.-a The usual
quarantine is obviously not working in Idaho.-a There can't be that
many herds left that have not been infected at least once since the
state was first infected in 2024. They likely have to start
restricting dairy worker movements from infected farms, and start
contact tracing and testing dairy workers and their human contacts.
As crazy as it may be it is still only a recommendation that dairy
workers on infected farms should not work on other farms.-a It has
been known since 2024 that around 10% of the dairy workers on
infected farms were getting infected, and the research dairy virus
line was cultured from eye swabs of the first Texas infected Dairy
worker.-a A lot of dairy workers are getting infected and they shed
live virus.-a It was just stupid that they essentially stopped testing
dairy workers after the found out that so many of them were getting
infected. The CDC claimed that they were going to start a testing
program, but that never happened, and they still do not do contact
tracing to determine how the new herds are getting infected.-a How did
Texas and Utah get infected again when cattle movements are restricted?
Ron Okimoto

Another dairy herd infected in Idaho.-a That makes 30 new herds
confirmed to be infected in June.-a The rate of increase means that
they are likely not restricting dairy worker movements.-a This includes
veterinarians that are known to have been infected in the past.-a If
they had started contact tracing in 2025 they likely could have
avoided these herd infections.
It is crazy that they are still not requiring dairy worker quarantine.
Restricting cattle movement is obviously not working.-a The denial for
political purposes is just stupid.
Ron Okimoto
A new Texas herd has been added to the link above.-a Both Utah and Texas
had been classified as "unaffected" (bulk milk tank negative for 6
months) and now both states have multiple herds affected (2 in Texas, 3
in Utah).-a The USDA has not counted reinfected herds so the extent of
the infections may not be known.-a Reinfected herds have not been listed
in the data set at their confirmation site.

are restricted, but 45 herds have been infected in the last 30 days in

testing and contact tracing when they knew from the first infected dairy worker (March 2024) that he was shedding live infective virus.-a They understand that around 10% of the dairy workers on an infected farm get infected (likely more than that because they tested the dairy workers
before the farms had cleared the virus, so 10% were the ones that had
been infected at the time of testing).-a They knew that infected workers shed infective virus, and they knew that a dairy workers from an
infected dairies worked on more than one farm including poultry farms.
In Michigan one dairy worker from an infected dairy had also worked on
one of the Michigan commercial layer farms that was infected by the
dairy virus.-a They never tested the dairy worker nor followed up to determine what dairy the virus that infected that poultry farm came
from.-a The virus may only be infective on skin and clothing for a matter
of hours, but noting will keep the birds from being infected if the
worker is shedding live virus.-a Changing clothing, and even showering before entering the farm will not protect the birds from an infected worker.-a California lost 40% of their commercial layer flocks, and never restricted dairy worker movements.
It is just nuts that the virus is being allowed to continue spreading to
new herds and other states.-a Veterinarians have to be included among
dairy workers because 3 veterinarians were found to have been infected
at some conference where blood samples were collected and none of them claimed to have experienced symptoms, but they had obviously mounted an immune response, so they were likely shedding virus at some time.

Two more herds, one in Idaho and another in Utah have been confirmed
to be infected.-a Since the USDA does not report reinfected herds the
true extent of the epidemic in Idaho, Utah, and Texas is not known.
No information as to how Utah and Texas were reinfected, and no
information on the genetic relationship of the virus infecting the
three states. The dairy epidemic seems to be restarting with over 30
new herd infections in June and 57 total in 2026.-a 171 new herd
infections were confirmed in 2025, but the USDA did not count herds
that had been infected, cleared the virus, and were subsequently
reinfected, so the true number of herd infections in 2025 is not

7 more herds infected in Idaho (64 total herds infected in 2026, 44 in
June)
It is probably time that they considered dairy workers as transmission
vectors.-a Idaho, Utah and Texas are still not requiring dairy worker
quarantine onto infected farms.-a It remains only a recomendation that
dairy workers not be allowed to work on other farms.-a Cattle movements
are restricted, but 45 herds have been infected in the last 30 days in
three states with Utah and Texas having had attained unaffected status
(bulk milk tank testing negative for 6 months) by May before being
reinfected.-a It is just crazy that they never started dairy worker
testing and contact tracing when they knew from the first infected
dairy worker (March 2024) that he was shedding live infective virus.
They understand that around 10% of the dairy workers on an infected
farm get infected (likely more than that because they tested the dairy
workers before the farms had cleared the virus, so 10% were the ones
that had been infected at the time of testing).-a They knew that
infected workers shed infective virus, and they knew that a dairy
workers from an infected dairies worked on more than one farm
including poultry farms. In Michigan one dairy worker from an infected
dairy had also worked on one of the Michigan commercial layer farms
that was infected by the dairy virus.-a They never tested the dairy
worker nor followed up to determine what dairy the virus that infected
that poultry farm came from.-a The virus may only be infective on skin
and clothing for a matter of hours, but noting will keep the birds
from being infected if the worker is shedding live virus.-a Changing
clothing, and even showering before entering the farm will not protect
the birds from an infected worker.-a California lost 40% of their
commercial layer flocks, and never restricted dairy worker movements.
It is just nuts that the virus is being allowed to continue spreading
to new herds and other states.-a Veterinarians have to be included
among dairy workers because 3 veterinarians were found to have been
infected at some conference where blood samples were collected and
none of them claimed to have experienced symptoms, but they had
obviously mounted an immune response, so they were likely shedding
virus at some time.
Ron Okimoto
3 more herds confirmed in Utah.-a No updates on what they are trying to
do to contain the virus.-a My guess is that it is only a matter of time before more states are infected again.-a For some reason they can't keep
the virus contained in Idaho and it is obviously spreading outside of
that state.

Ag Daily seems to be a national agricultural news site.-a The article
notes that Idaho has the most dairy infections and that poultry farms
are also being infected in Idaho.-a Utah just lost a 1.2 million bird
layer farm in the same county as half a dozen dairies have now (edit from not to now) been
infected.
The article notes that the virus does not seem to be spread by wild
birds, but is spread dairy to dairy.-a They blame animal movements, but
no cattle are going to poultry farms.-a All infected states have restrictions on cattle movements, but none of them are restricting dairy worker movements (this would include veterinarians).-a They seem to have
no clue how the poultry farms are being infected even though they acknowledge that they are being infected by the dairies, and that dairy workers also work on poultry farms.-a Dairy workers routinely work on
more than one farm.-a They do not work full time at one dairy.

Two more herds, one in Idaho and another in Utah have been
confirmed to be infected.-a Since the USDA does not report
reinfected herds the true extent of the epidemic in Idaho, Utah,

the virus infecting the three states. The dairy epidemic seems to

7 more herds infected in Idaho (64 total herds infected in 2026, 44
in June)
It is probably time that they considered dairy workers as
transmission vectors.-a Idaho, Utah and Texas are still not requiring >>>> dairy worker quarantine onto infected farms.-a It remains only a
recomendation that dairy workers not be allowed to work on other
farms.-a Cattle movements are restricted, but 45 herds have been
infected in the last 30 days in three states with Utah and Texas
having had attained unaffected status (bulk milk tank testing
negative for 6 months) by May before being reinfected.-a It is just
crazy that they never started dairy worker testing and contact
tracing when they knew from the first infected dairy worker (March
2024) that he was shedding live infective virus. They understand
that around 10% of the dairy workers on an infected farm get
infected (likely more than that because they tested the dairy
workers before the farms had cleared the virus, so 10% were the ones
that had been infected at the time of testing).-a They knew that
infected workers shed infective virus, and they knew that a dairy
workers from an infected dairies worked on more than one farm
including poultry farms. In Michigan one dairy worker from an
infected dairy had also worked on one of the Michigan commercial
layer farms that was infected by the dairy virus.-a They never tested >>>> the dairy worker nor followed up to determine what dairy the virus
that infected that poultry farm came from.-a The virus may only be
infective on skin and clothing for a matter of hours, but noting
will keep the birds from being infected if the worker is shedding
live virus.-a Changing clothing, and even showering before entering
the farm will not protect the birds from an infected worker.
California lost 40% of their commercial layer flocks, and never
restricted dairy worker movements.
It is just nuts that the virus is being allowed to continue
spreading to new herds and other states.-a Veterinarians have to be
included among dairy workers because 3 veterinarians were found to
have been infected at some conference where blood samples were
collected and none of them claimed to have experienced symptoms, but
they had obviously mounted an immune response, so they were likely
shedding virus at some time.

3 more herds confirmed in Utah.-a No updates on what they are trying
to do to contain the virus.-a My guess is that it is only a matter of
time before more states are infected again.-a For some reason they
can't keep the virus contained in Idaho and it is obviously spreading
outside of that state.

3 more herds in Utah have been confirmed to be infected, and still no
state is requiring dairy worker quarantine.-a Cattle movements are
restricted, so how are the herds being infected?
Ron Okimoto
Two more Texas herds showed up on the web site today, but they claim to
have been confirmed before the last 3 Utah herds.
Still no announcements by the USDA as to genotype and what is being done
to determine how Utah and Texas were reinfected after having cleared the virus.-a The virus is spreading to new herds in all 3 states (Idaho,
Utah, and Texas).

Another Utah herd confirmed infected.-a 10 total herds in Utah in 2026
with 8 in the last 30 days.-a 4 herds infected in Texas in 2026 with 3 in the last 30 days.-a 59 herds in Idaho infected in 2026 with 9 infected in the last 30 days.-a The USDA has not been counting reinfected herds on
this list so the extent of the epidemic is likely not known in terms of total infected herds in 2026.-a They acknowledge that the virus is spread
by cattle, personnel, and/or equipement transferred between farms, but
no state has a restriction on dairy workers working on more than one
farm.-a Cattle movements are restricted, but not dairy worker movements,
and they still refuse to acknowledge that they should have been testing
and contact tracing dairy workers from the beginning of the epidemic in 2024.
California was the only state to implement contact tracing and it was so successful that the USDA started helping them do it late in 2024, and
they identified a record number of infected dairies for any state.-a Most states just stopped testing their dairy herds, so until bulk milk tank testing was initiated the other states did not know how many herds had
been infected.-a Before they stopped testing dairy workers California had also identified the most infected dairy workers.-a Bulk milk tank testing was not implemented until most infected states had pretty much cleared
the virus (it had likely run through the herds in those state).-a Google claims that contact tracing of dairy workers became routine in
California.-a This means that California likely fully understood how the layer flocks and other commercial flocks were being infected by the
dairy virus, but none of their contact tracing results were ever
published nor acted upon in terms of restricting dairy worker movements
off infected dairies.-a California never restricted dairy worker
movements and over 80% of their dairies were infected and they lost 40%
of their commercial layer flocks and a bunch of meat bird flocks.

Another Idaho herd has been confirmed to be infected July 13th.-a Since
they are claiming that they understand that the infection is spread by cattle, personnel, or dairy equipment, from herd to herd, there is no
reason for them not to have restricted dairy worker movements, but all
the infected states refuse to do that and the virus is spreading again.
They do restrict cattle and equipment movement off infected farms, but
for some reason they will not do what is necessary to stop the spread by restricting dairy worker movements from infected farms.-a It is stupid
since they have known since the first infected dairy worker that he was shedding live infective virus.-a They created the research virus culture from his eye swabs, so they know that the dairy workers can shed live
virus on other farms, and they have known that dairy workers from
infected daries had also worked on the poultry farm infected in Michigan very early in the dairy epidemic.
The dairy epidemic has spawned a stupid science denial strategy in order
to deny and minimize the impact of dairy worker infections.
