Commercial pigs in Ind. test positive for H1N1

WASHINGTON -- — The U.S. Department of Agriculture said Wednesday that pigs in a commercial herd in Indiana had tested positive for swine flu, making it the first time the virus has been found in such hogs.

The USDA said it discovered four tissue samples that tested positive for the virus using its swine surveillance program.

The sample was collected in late October, and the USDA said the pigs as well as the people caring for the animals had recovered.

Last month, tests confirmed that several show pigs at the Minnesota State Fair contracted swine flu, also known as the H1N1 virus.

The USDA declined to identify the Indiana location of the sick pigs.

USDA officials have stressed that instances of pigs with swine flu do not pose a threat to consumers of pork products.

Still, word of a commercial herd contracting the virus is bad news for the pork industry, which has struggled with poor prices blamed on swine flu fears and the global recession.

Agriculture experts expected that swine flu would eventually show up in domestic swine. A vaccine for hogs is being developed.

The positive tests in Indiana came just days after U.S. officials successfully negotiated an end to one of the more damaging commercial effects of swine flu -- a six-month ban on pork imports to China. Officials expect the Chinese to reopen their import markets.
