32 Cattle Herds Quarantined Because Of Bovine TB

OMAHA, Neb. (AP) — Officials have now quarantined 32 herds with about 15,000 adult cattle in north-central Nebraska, so testing for bovine tuberculosis can be completed.



State Agriculture Director Greg Ibach (eye-BAW) said Thursday that most of those herds were quarantined because the animals had contact with a Rock County herd where two animals have tested positive for bovine TB.



The quarantined herds are in Rock, Holt, Loup, Boyd and Brown counties.



State officials are working with the U.S. Department of Agriculture to investigate the TB cases and determine whether Nebraska can keep its tuberculosis-free status.



Ibach says it will take several months to complete the investigation.

Cattle TB Confirmed In Texas


Cattle tuberculosis (TB) has been confirmed in a west Texas dairy quarantined since April when some cattle in the herd responded to a TB test being conducted prior to a sale. (The sale was cancelled.)

“The infected herd remains quarantined while the final disposition of the herd is determined - either slaughtering the herd, or repeatedly testing and removing infected animals until the herd is free of cattle TB,” says Bob Hillman, Texas state veterinarian and head of the Texas Animal Health Commission (TAHC). “Dairy, calf-raising and dairy animal replacement operations with epidemiological links to the infected herd are being tested to determine both the origin and potential spread of the disease.”

Hillman encourages ranchers or accredited veterinarians to call the state of destination prior to shipping bison, beef or dairy cattle out of Texas, as some states may impose enhanced TB entry requirements on Texas cattle and bison.

Hillman adds that Texas’ cattle TB-free could be in jeopardy if the infected dairy cannot be depopulated, or if a second infected herd is detected within 48 months.

Nebraska, in early June, confirmed TB infection in a beef herd. Currently, California and Minnesota are not cattle TB-free, and areas in Michigan and New Mexico have specified zones that are not TB-free. When TB-free status is lost, breeding cattle and bison moved out of a state need a negative TB test within 60 days prior to shipment, or animals must originate from a herd that has accredited TB-free status, achieved through a formal testing and retesting program.

When exposed to cattle TB, an animal’s immune system will fight the invasion by encapsulating the bacteria. This can cause the formation of lesions or growths in and on lymph nodes, mammary glands, lungs and other internal organs. Although infected, the animals may appear healthy until the latter stages of the disease, when signs may include weight loss, coughing or breathing difficulties. The disease is not treatable in livestock.
