US - Tests for pseudorabies on pig herds in the final quarantine area of Clark County, have proved negative. Officials say that this should now clear the way for Wisconsin to retain its pseudorabies-free status.

All herds that tested negative have been released from the quarantine restrictions, which were put in place to prevent the spread of the viral disease.

The two herds where the disease was originally discovered, one with 300 pigs near Greenwood and the other with 27 near Loyal, were culled last week.

The diseaase was detected through routine surveillance at the slaughterhouse and the Greenwood unit was the first commercial US herd to contract the pseudorabies since 2003.

Federal officials classified both of the infected herds as transitional. Deducing that the infection had probably come from contact with wild pigs. This is considered less of a risk to the commerical pig industry than if infections are brought in from other herds.

State Veterinarian Robert Ehlenfeldt said that tests had proved negative on farms located within a five miles radius of both the Loyal and Greenwood units.

The pigs on farms within two miles of the infected herds will be tested again, following the thorough cleaning and disinfection of the Greenwood and Loyal sites.

With the completion of all testing porcedures and the destruction of infected animals, state officials managed to achieve the 15-day deadline set down by the US Department of Agriculture for Wisconsin to be declared officially clear of the disease.
