Dairy cows must be tested for bird flu before moving across state lines under a federal order to be issued Wednesday, as evidence mounts the virus is more widespread than feared among cows in the United States.
Biden administration officials said the move is meant to contain transmission of the virus known as H5N1 and to reduce the threat to livestock, but they maintained that the risk to humans remains low.
I wonder if I should be more worried about this than I am? H5N1 is now in cows, chickens, eggs, milk, and one person.
But it's spread to people before—hundreds of them, in fact, over the past couple of decades. So this is nothing new. Still, I wonder how many mutations away it is from learning how to spread via humans?
Well, you probably have a weakened immune system, which might make it reasonable to be extra careful. We don't want to lose you.

Speaking of noxious viruses
The key takeaway is that selling raw milk to the public should be illegal.
I believe it already is for inter-state. Intra-state will probably vary.
“I wonder how many mutations away it is from learning how to spread via humans?”
Sounds like a job for Gain-of-Function experiments! 😐
Given one cannot control the interstate movements of wild birds, this testing of dairy cows prior to interstate movement seems akin to closing the international border after COVID was established in the country.
The chance of infection is all about duration and intensity of exposure. We don't interact with wild birds but people spend all day with cows raising and slaughtering them. This will reduce the probability of interspecies transfer.
The cows are out in the fields, where as I understand it, they contracted the virus from wild birds. The proverbial horse as it were has long left the barn. So more cows will continue to contract the virus, meaning that absent a vegan’s wildest dreams come true there will continue to be human contact with cows.
Well, just because bird-to-cow transmission happens in wild virus variants doesn't mean it's pointless to care about cow-to-cow transmiting variants; after all, we mostly care about bird flu because we don't want it to spread mammal-to-mammal (and to one hairless ape mammal species in particular).
Tick. Tick.Tick...
It is something to watch. If it does move into human-to-human transmission, it could become fairly good at it before we catch it. America's dairy farms are very dependent on rural immigrant labor, which could delay the public health system spotting it.
The risks of flu to the young are also a huge concern. Babies cant be vaccinated right away, and our health system relies on a lot of parents of young children. We cant afford to have lots of healtcare workers disappear from work.
An acquaintance who is a doctor of infectious diseases said don't drink raw milk or eat raw eggs. I guess no sunny side up eggs.
If you get your egg yolks to 155 degrees for about 155 seconds, you'll kill most bacteria. Put a lid over your pan, keep the eggs sunny side up, and you'll achieve that just as the yolk is starting to coagulate.
Don't know about avian flu, but you may need a higher temperature to kill that virus 🙁
One would think that it wouldn't be that hard to develop a new flu vaccine but with nearly 50% of the population now convinced that vaccines, not diseases, are deadly the odds of containment are pretty low.
We typically monitor outbreaks in southeast Asia to prepare flu shots for the US school year. There it's the intermingling of wild birds, pigs and people. The Spanish flu originated in the US (Kansas I think), so it can happen anywhere. And we've already had bouts of "bird flu" and "swine flu" in my lifetime, and they will happen again. Flu viruses jump species all the time, though they won't all spread in the new species. Watchful waiting for now.
*Probably* in Kansas -- that's John Barry's hypothesis, and it's pretty convincing. But there are other possible origin sites, including China.
If you can only choose one pathway due to the sheer cost and federal budget pressures from the GOP, do you choose to invest in R&D for a vaccine for humans, chickens, or cows?
