The l998 outbreak involved only horses," said Dr. Max Coats, deputy director for the TAHC's Animal Health Programs.
"On one of the premises in Starr County, one cow among a handful of cattle tested positive for VS, and no other susceptible animals are on the site.
On the second premise, the owner has an infected cow and horse, and there are about 30 other head of cattle and several horses that, at this point, have no clinical signs of VS and they have tested negative for the disease," he
"Stock covered by the breeding cattle testing and identification requirement include weaned heifers, bred heifers, cows and bulls intended for breeding purposes," explained Dr. Max Coats, assistant executive director for the Texas Animal Health Commission, the state's livestock health regulatory agency.
"The USDA has delayed until Jan. 1, 2003, additional restrictions on moving feeder cattle out of the state.
Feeder animals include steers, bull calves and heifers destined for grazing and feeding for slaughter.
"We've worked to prepare Texas cattle producers for the impact of this regulation change for several months and have conferred frequently with related industry associations.
Brochures outlining the changes in the testing requirements can be obtained from the TAHC at no charge," Coats said.
This new federal regulation will require ranchers to plan ahead before selling or moving their breeding cattle out of state, he said.
"Ranchers may find their breeding cattle to be more marketable if the animals are tested prior to arrival at the livestock market," he added.
"Untested breeding cattle and bison will be restricted to movement only within the state or directly to a slaughter plant, unless a buyer makes arrangement to have the animals held and tested after the sale.
Ranchers will be responsible for paying their USDA accredited, private veterinary practitioners for testing.
Conducting a TB skin test To conduct a TB skin test, an accredited veterinarian injects a tiny amount of tuberculin into the animal's skin near its tail, in an area called the caudal fold.
After a 72-hour waiting period, Coats said the veterinarian examines the site for swelling that might indicate the animal has been exposed to cattle TB.
If there is no response, the accredited veterinarian can issue a document as proof of testing, recording on it the test results and the animal's official identification -- either a brucellosis ear tag, or for purebred cattle, a firebrand or tattoo registered with the breed.
"About 1 percent of the caudal fold tests will be positive, and this is expected, as there can be false-positive test results, Coats said.
"If this occurs, a state or federal veterinarian must run a second test within 10 days.
This comparative cervical test, run on the animal's neck, also requires a 72-hour waiting period, and if it is negative, the animal can move freely.
"A positive test, however, is strong indication the animal may have cattle TB, and it must be slaughtered and carefully examined for internal TB lesions.
"Tissue samples will be collected and forwarded to the National Veterinary Services Laboratory in Ames, Iowa, for laboratory confirmation.
There are three exceptions to the TB testing requirements for breeding cattle moving across state lines, said Coats, who heads up TAHC's field operations and animal health programs.
"Nursing calves can move without a test, if they accompany their TB-tested dam," he said.
"Cattle going directly to a slaughter plant from a farm or livestock market don't need a test.
Ranchers also can move animals freely from a TB accredited-free herd, a status gained through annual herd testing.
Coats advised producers to call the TAHC at 800/550-8242 for information about the TB accreditation program.
"We are working with the USDA, states that receive our cattle, and the livestock industry to develop a plan for adequately identifying feeder steers and spayed heifers moving out of Texas on or after Jan. 1, 2003," Coats said.

"I don't see any reason for worry on the part of consumers as a result of what we've seen in this flock," said Dr. Max Coats, a poultry expert with the Texas Animal Health Commission.
The destroyed chickens did not produce eggs for consumption.Eggs from this farm are taken off site for hatching and become broiler chickens, he
said the outbreaks are unrelated.
Bird flu also has been detected in Delaware, Maryland, Pennsylvania and New Jersey this year.
Testing done at the farm about 10 days ago found a "significant number" in the flock showed antibodies to bird flu, Coats

The 100 chickens that remained at Brobbey's market and chickens and ducks at the three other markets have since been destroyed and allowed to enter the food chain, said Dr. Max Coats, deputy executive director of the Texas Animal Health Commission.
"Any kind of food preparation will inactivate the virus," he
said, adding the strain of the virus found in Texas does not pose a health risk to humans.
said testing was under way at all of the chicken farms within a five-mile radius of the farm where the avian flu was found in Gonzales County.Most of the tests have come back negative with the exception of the initial farm and the two markets in Houston, he
Few of the chickens have become sick from the virus, which Coats
said is "definitely a sign that we caught it early on.
"We have done lots of testing and have not found any other signs of disease," he
While the news was encouraging Tuesday, Coats
said there was still much to do to try to pinpoint the cause of the virus and win back consumer confidence.

Dr. Max Coats, deputy director of the Texas Animal Health Commission, said some 250 flocks were sampled in the search zone, and that all of the tests have come back negative.
said 19 area flocks with links to the infected farm will be retested weekly for at least four weeks, and during that time chicken farmers within five miles of the infected farm will need a state or federal permit to move birds or eggs out of that area.
