- Again, we need to secure our borders, especially with
Mexico, to guarantee that cattle are not being shipped with Bovine TB from
Mexico where Bovine TB is prevalent.

- Bovine Tuberculosis Found In 2 Dairy Herds
-
-
- Tuberculosis has been found in 2 dairy herds in Roosevelt
County, New Mexico Cattle Growers Association president Phil Bidegain said.
The detection of bovine tuberculosis means the state will be reclassified
from its tuberculosis free status under the U.S. Department of Agriculture's
tuberculosis rule developed in 2000.
-
- "While this reclassification will have virtually
no impact on consumers of beef and milk in New Mexico or elsewhere, it
will have tremendous impact on livestock producers in the state,"
Bidegain, of Tucumcari, said. "New Mexico is the 4th state to fall
under the federal tuberculosis rule. It has already been detected in Michigan,
Texas and California," Bidegain said.
-
- The drop in status will require beef and dairy cattle
owners transporting cattle out of New Mexico to test for tuberculosis.
Ranchers would have to give each animal an injection [tuberculine test]
and put them in a chute to read the test 3 days later. All infected animals
in a herd must be killed.
-
- A lack of large animal veterinarians in the state could
also make testing difficult, Bidegain said.
-
- Under the USDA tuberculosis rule, the state must now
develop a plan on how it will regain its tuberculosis free status.
-
- Texas ranchers have said more restrictions should be
placed on Mexican herds entering the United States after the discovery
of tuberculosis in dairy cows in Pecos County and beef cattle in Fayette
County last year [2002]. Although the government required all breeder herds
in Texas to be tested, it waived the requirement for feeder cattle. Ranchers
in Texas have said the best way to wipe out the disease is by controlling
high-risk animals, including dairy herds and cattle from Mexico and other
places where bovine tuberculosis is prevalent.
-
- Bidegain said the state may opt to regionalize, which
means only livestock in a designated region must be tested. The rest of
the state would be allowed to move cattle under the current system. But
he warns that the plan development and approval period could take up to
2 years.

- [Bovine tuberculosis is a chronic bacterial disease caused
by the acid-fast, slow-growing rod-shaped _Mycobacterium bovis_; transmission
to humans constitutes a public health problem.
-
- Aerosol exposure to _M. bovis_ is considered to be the
most frequent route of infection of cattle, but infection by ingestion
of contaminated material also occurs. Characteristic tuberculous lesions
occur most frequently in the lungs and the retropharyngeal, bronchial and
mediastinal lymph nodes. Lesions can also be found in the mesenteric lymph
nodes, liver, spleen, on serous membranes, and in other organs. - Mod.AS]
