The American Department of Agriculture has announced the detection of the bird flu virus (H5N1) in a pig on a small family farm in Oregon, marking a rare first in the USA. The virus was confirmed in one of five pigs, which were all subsequently slaughtered to prevent any transmission. The quarantine of the farm and ongoing monitoring of other animals aim to limit further spread, while the event is not expected to affect pork supply security. The incident underscores the need for biosecurity measures, especially on farms with diverse animal species, as the U.S. grapples with widespread bird flu in cows.
