@HelenBranswell on top of it again today. Lots of good tidbits in this one.

"an animal to test negative for the virus before it can be moved across state lines"
"farms that move cattle across state lines and have animals that test positive for H5N1 or any influenza A virus will be required to open their books to investigators, so they can trace movement of cattle from infected herds"
"The order currently applies to lactating dairy cows but could be expanded if necessary"
"He sidestepped questions about where the positive milk samples were purchased and what percentage of samples contained traces of the virus when tested by PCR — polymerase chain reaction testing — saying that the agency has an analysis of its work that will be made public “very shortly.”"
"There was some support offered for the oft-repeated claim that pasteurization would kill the virus in milk from by Jeanne Marrazzo, the new NIAID director. She said that some NIAID-funded researchers had also found PCR-positive milk in samples bought from stores, but that when the researchers tried to grow virus from those samples, they could not.
“The results that those investigators got indicated that the PCR-positive material was not alive,” Marrazzo said, though she warned that work was done on a small number of samples and needs to be confirmed by the larger FDA effort."
"Watson confirmed that USDA has met some resistance from farmers who they’ve suspected of having infected cows. Farmers have been told they must discard any milk produced by cows that are infected with H5N1 virus, though it’s not clear if or how that recommendation is being enforced."
An article from today about the possibility of this H5N1 spread being similar to the spread of contagious mastitis in cows. It's from the perspective of the industry.

I also read way more about contagious mastitis than I ever wanted to, but, if anyone is interested this article was a good review.
@BE I'm concerned about ranch run off, on vegetables. Like how we get E. Coli on romaine so often. Eggs, meat, you can cook well and be ok, at least AFAIK. Milk, if the virus is life in there, that's not good. But I'm already getting organic farm produce, not near ranches. 🤷🏼♀️
I've thought a bit about this for gardening and growing your own vegetables, at least. While I couldn't find a good study on H5N1, specifically, a 10% vinegar wash does inactivate H1N1.
A lot of people do wash veggies with vinegar solution already, so it seems like a good idea when possible given the possibility of wild bird feces anyway.

(Edited to add the paper 🙄 )
@BE I need to get that system going.
I've also been asked a lot whether we're in panic mode here, and if we're running off to the homestead.
No, not at this point. We, obviously, already take airborne precautions. Please don't forget about COVID.
Last night my wife and I did make the decision to stop using grocery store milk. We really only buy 2 gallons a month. It's not a big deal to us, so it seems like an easy thing to do. We use it to make kefir, and kefir can, under some circumstances, harbor and facilitate the growth of viruses from what I've read. So the kefir grains are going to stop being fed for the moment. Sorry kefir grains.
If I bought a lot of ground beef from the store would I be worried? Hard to tell since it's not something we do, but, I guess I'd be cooking it to a higher temperature, at least.
Know your egg substitutes.
Crises precipitate change. Don't be afraid to be flexible as circumstances change.
Otherwise, we're just keeping up to date and seeing what goes on.
