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.
