Thank you for that link; that's an excellent and easy to read paper on the current situation.

Of immediate relevance to this thread is the scene-setting at the beginning and the exhortation at the end:

"In early 2024 this virus entered dairy cows in the USA by an unknown means and has since infected cows in over 195 herds in 13 states (data as of August 2024). Although the infection in cows leads to transient mild disease, the infection appears to be concentrated in the udders, leading to very high levels of virus in the milk for 4–6 weeks during infection. Fortunately, the pasteurisation process destroys the viability of the virus, but dairy workers are still at risk when milking infected cows as the virus remains infectious on milking equipment, and the unpasteurised milk contains very high virus loads...

"In cattle, where control measures are possible, it will be critical to stop spread as continued transmission provides an ‘open air’ experiment for the potential emergence of further mammalian-adapted mutations and spread back into avian populations (which has already occurred) and into other species."

Taking chicken shit out of feed for cows and beef cattle is an obvious way to cut this risk at source.

yep. While it's true that the waste of some beings is the fuel of others', it's not always true. And it is sometimes inversely true in the extreme as in that waste is lethal.

Weekly CDC response dated 11/4/24: https://www.cdc.gov/bird-flu/spotlights/h5n1-response-11012024.html
 
5 more human cases of H5N1 were reported today in California, as well as one human case in Oregon.

They also published details about the infected teen in Canada, who has a mutation that matches a strain found in a wild goose. It’s got the same adaptation (E627K) found in cattle that is making it easier for humans to catch.

(Eta the mutation name)

this looks like more rumour-/ scare-mongering. Did you read the report that @Nym linked to in #61 above https://www.backyardchickens.com/threads/bird-flu-in-dairy-cattle.1616347/post-28138809
or indeed any of the sensible links in the last few pages? If you don't understand something, just ask.
 
Yes I read through it. I have little trust left in the CDC with the way they’ve handled Covid, which ravages our immune systems and is still killing over a thousand Americans most weeks.

The news is coming in faster than the CDC can update:
