Officials say bird flu has been detected in pigs for the first time in the United States

Government officials said it was the first time in the U.S. that a pig had tested positive for H5N1 bird flu.

According to a press release from the United States Department of Agriculturethe pig was involved in a “backyard farm” in Oregon where other poultry and livestock tested positive.

The pig is one of five on the farm that shares water sources and housing with other farm animals and poultry.

Two of the five pigs tested negative for the H5N1 virus, and officials said they were still waiting for test results for the remaining two pigs. All the pigs were euthanized.

Officials said the farm, located in Crook County, is non-commercial and the animals are not intended for commercial food supply.

“As a result of this finding, there is no concern about the security of the domestic pork supply,” the USDA said.

The farm has been quarantined to prevent further spread of the virus, and other animals, including sheep and goats, remain under surveillance.

Genome sequencing of the virus from infected farm-raised poultry showed no changes to suggest the virus is more transmissible to humans, the USDA said, so the risk to the public remains low.
