The U.S. is continuing to take steps to keep African swine fever out of the country.
Farm Journal's Pork recently reported that the USDA recently announced it has approved blood swabs and spots as official African swine fever (ASF) testing tissues.
Paul Sundberg, executive director of the Swine Health Information Center, says more work needs to be done to fully integrate these new samples into the active surveillance program, as well as the ASF Red Book.
