There are some dumb responses in this thread. Lots of misplaced vitriol at Texas and farmers.
You want to have people report this stuff? Don't act like dickheads when they do.
Stuff like this happens from time to time in agriculture. UK has issues with TB in dairy cows which requires them to cull herds. It's really shitty and unfortunate but this type of thing has happened for millenia.
It's better that they report it so we can address it and find ways to prevent it happening in the future.
And unless everyone is willing to go 100% vegan tomorrow, we need farmers, livestock, and the like to keep our meat and dairy supply flowing.
Edit:
I also want to point out that it doesn't seem like.they definitively determined it came from the cows but that he was "link" and "exposed" to infected cows.
"Genetic tests don’t suggest that the virus suddenly is spreading more easily or that it is causing more severe illness, Shah said. And current antiviral medications still seem to work, he added."
So this guy could have gotten it from the same bird the cows got it from as well. A dozen other people were tested and none came back positive.
All other cases we've seen have come from bird contact. So there is a reasonable chance this guy got it from an infected bird without realizing it.
Also, none of the cows have died (dunno if that's a good thing or bad thing).
