Nebraska cattle herds quarantined for bovine TB testing

Officials have quarantined 32 herds with about 15,000 adult cattle in north-central Nebraska so that testing for bovine tuberculosis can be completed.

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, according to State Agriculture Director Greg Ibach.

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

State officials are working with the USDA 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.
