America only?
Is this allowed / banned, rare / common elsewhere in the world? — GhostInTheMachine talk to me 08:55, 3 November 2023 (UTC)


 * It's doesn't seem to be exclusive to the US, but it is a bit more difficult to find sources talking about it outside of the North America. That could also just be that I am not searching for it efficiently
 * One thing I could find is that it seems the Japanese government generally recommends against its use for PED prevention, but it still occurs there. Article notes at least one specific case where it was used
 * "Because it is challenging to control feedback and
 * provide stable results completely, Japanese government
 * published the PED prevention manual to guide farmers
 * not to perform feedback unless veterinarians or applic-
 * able government agencies are involved"

 * @GhostInTheMachine, going back to this, I was able to find some more information about other countries with more complicated boolean searches to look at feedback usage after PEDV in particular.
 * Its had wide use in at least the US, Taiwan, Japan, South Korea after the 2013 PEDv outbreak. There was wide use in Europe after it PEDv first emerged in the 1970s.
 * I believe there was also wide use in Canada after the 2013 outbreak, but the sources are unclear. One case study of its use in an Ontario farm called its usage common, but I couldn't tell if that was for Canada, for North America as a whole, or just generally around the world. There is another source talking about its use on one farm after a PEDv detection in 2019, but I again couldn't tell how widespread
 * I started a section for the article noting what I could find good sourcing for. Will continue to look for more.
 * I don't think it is banned anywhere from what I can tell. I seem to be always able to find a study looking at least one specific usage of it in just about every country I search for. At best some countries seem to not recommend it, but none seem to prohibit it and it can even be widespread in some of the countries that don't recommend it
