Federal testing has identified the swine flu in pigs at two North Carolina farms.
The results released Wednesday makes North Carolina the 10th state with identified cases of swine flu in animals. State Veterinarian David Marshall said the presence of swine flu in pigs is not unexpected and the cases show that the surveillance system is working.
Health officials said people cannot contract the swine flu from handling or consuming pork products. They said it appears the pigs at both farms caught the virus from humans.
The states of Minnesota, Indiana and Illinois have confirmed cases of swine flu in pigs. The virus also been identified in cats, ferrets, turkeys, a dog and a cheetah in other states.
(The location of the farms in North Carolina has not been released.)
