EcoHealth's raccoon dog catch and release program detailed in @WhiteCoatWaste FOIA. Feb 2017 email from NIH sought details on EH testing program.
Bat samples were sought methodically throughout SE Asia. Other mammals, including raccoon dogs. would be "opportunistically" sampled from live markets and farms. I read that to mean, when we get the opportunity to sample from markets, we will. HSM would seem a good opportunity.
