Bird flu was detected in a pig for the first time in the United States, officials said

This is the first time in the United States that a pig has tested positive for H5N1 avian influenza, government officials said.

According to a USDA press release.the pig was part of a “backyard farming operation” in Oregon where other poultry and livestock had tested positive.

The pig is one of five on the farm, sharing water sources and housing with other livestock and poultry.

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

The farm, located in Crook County, is not a commercial operation and the animals were not intended for commercial food supply, officials said.

“As a result of this discovery, there are no concerns about the security of the nation’s 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 observation.

Genomic sequencing of the virus from infected farm poultry found no changes to suggest it is more transmissible to humans, so the threat to the public remains low, according to the USDA.
