Xinhua News Agency, Las Vegas, October 31 (Xinhua) -- The U.S. Department of Agriculture announced on the 30th that the highly pathogenic H5N1 avian influenza virus was detected in pigs at a private backyard farm in Oregon. This is the first report of pigs infected with H5N1 avian influenza in the United States.
According to the U.S. Department of Agriculture, the farm where pigs were found to be infected with H5N1 avian influenza is located in Crook County, Oregon. The poultry and livestock raised on the farm share water sources, housing and equipment. Other states in the United States have found cross-species transmission of viruses in such farms.
The Oregon Department of Agriculture announced on the 25th that the poultry on the farm had detected the H5N1 avian influenza virus. Although the five pigs raised on the farm did not show symptoms of illness, the agricultural department still tested them for the virus. One pig tested positive, two tested negative, and the results of the other two are still pending. The five pigs have been euthanized, and other animals raised on the farm are still being monitored. The farm has been quarantined to prevent further spread of the virus.

The U.S. Department of Agriculture said that the farm is not a commercial farm, and the poultry and livestock raised there are not used for commercial food supply. The incident will not pose a threat to the safety of the U.S. pork supply. The risk posed by H5N1 avian influenza to public health is still low.
The U.S. Department of Agriculture said that it is stepping up the development of avian influenza vaccines to curb the spread of avian influenza viruses among animals. Currently, two candidate vaccines for dairy cows have been approved for safety trials, and vaccines for other species will continue to be developed.
The U.S. Centers for Disease Control and Prevention recommends that the public take protective measures against avian influenza, including avoiding contact with wild birds and sick or dead animals.
