Bird Flu Hits United States, Tyson Foods Chickens Test Positive

About 15,000 chickens from Tyson Foods, Inc. in Arkansas have tested positive for H7N3, also known as Bird Flu or Avian Influenza. H7N3 is another low pathogenic strain of the disease similar to H5N1 which is more highly pathogenic.

The birds in question showed no signs of illness and the company says there was little risk to humans. A company spokes person said the incident was very low risk.

Tyson Foods said it will step up its testing for bird flu in response.
