Dairy cattle in Nevada have been infected with a new type of bird flu that’s different from the version that has spread in U.S. herds since last year, Agriculture Department officials said Wednesday.

The detection indicates that distinct forms of the virus known as Type A H5N1 have spilled over from wild birds into cattle at least twice. Experts said it raises new questions about wider spread and the difficulty of controlling infections in animals and the people who work closely with them.

“I always thought one bird-to-cow transmission was a very rare event. Seems that may not be the case,” said Richard Webby, an influenza expert at St. Jude Children’s Research Hospital.

    Being able to eat meat doesn’t mean you have to. Something that (perhaps slightly irrationally) annoys me about some people. They act as if a meal requires meat and then complain at how expensive food is to buy. Laughs in omnivore £15/week each diet. But by not being actually vegetarian I can still have things like Worcestershire sauce too.

      Yeah and its annoying the vegans that are so militant they discourage meat reduction in diets. Beef is so much worse (both health and environment) than most other meats that getting a large amount of folks to give up or massively reduce beef consumption is way better than a much smaller number becoming vegan.

        Just look at /r/vegan, even if you don’t eat/use animal products you are still not a vegan unless its for their specific reasons. If you do it for environmental reasons they decide you don’t count as a vegan.

          because of data. water usage and calorie conversion ratio on environment and fatty foods for diet. Im not going to do a web search for you as these things are well known and don’t go into places are only good for grazing or such as im talking reduction and not elimination. Just note Im only going to give so much effort toward any questions you want to pose as again this is not super controversial or hard to find information.

                but where did you get those? because i’ve found some LCA meta “studies” that i don’t trust which are usually the ones trotted out. i was hoping you had good data sources.

                  I mean I have never looked into the studies that are the basis for the data but while I think its possible in the details I really doubt the overall would be wrong. Water usage and calorie wise it pretty much falls in line with smaller animals using less for each calorie. I really doubt people are hyping crickets capability to convert plants into cricket vs cows making plants into cow. Its common sense enough that Im not looking to determining how well the studies were done as I don’t do that for most things as most people don’t who still work a job enough to eat and such. Conversely if you know about bad studies I would not mind you giving me what you have. I have just done a quick search using terms like misleading and scam and such and nothing seems to come up.

                    poore-nemecek 2018 is oft-cited. it is the one that is often used to justify the claim you made. but that meta “study” misuses its source data: LCA findings are not transferable between studies. this is explicitly stated by some of of the source papers which also violated this rule, but poore and nemecek disregarded this guidance and didn’t even mention it.
