State veterinarians conduct TB tests

Apr 20, 2017 - From staff and wire reports

Veterinarians from the Department of Agriculture are currently investigating and testing cattle that were potentially exposed to tuberculosis in South Dakota.

Wyoming State Veterinarian Jim Logan was notified March 13 that South Dakota's Animal Industry Board and USDA APHIS are investigating a beef herd with TB located in Harding County, S.D.

This herd was identified in late February after routine slaughter surveillance discovered three cull cows with lesions. During the epidemiologic investigation, South Dakota found there were 86 heifers purchased from the TB-affected herd and imported into Wyoming prior to the discovery of the infection. The animals were imported legally into Wyoming.

WLSB state veterinarians immediately began an epidemiologic investigation to determine where any exposed heifers from the affected South Dakota herd are currently. Many of those animals still belong to the Wyoming producer who originally purchased them. The veterinarians are also working with a couple of other Wyoming producers who purchased animals from the original importer/producer.

Logan noted all producers involved have been very cooperative.

"In order to protect the Wyoming cattle industry from TB, we are taking every precaution to assure that, if it happened to come into Wyoming in these purchased cattle, we will get it found and eliminated before there is disease spread," said Logan. "This involves herd testing and removal of all of the heifers that came from the South Dakota herd direct to slaughter with regulatory veterinarian examination at slaughter."
