10 Mar 2020 --- Additional measures to protect the US against African swine fever (ASF), if the virus is ever detected in the country, have been put in place by the US Department of Agriculture (USDA). The US government has been working to protect its pork industry for many months since ASF first took hold and rapidly spread across Asia and some European countries. Controlling and eradicating the virus is at the center of the action plan, should it ever get into the US.
