One more herd with TB means one rung down the ladder


Thursday, February 14, 2008 2:25 PM CST

  


Minnesota's cattle operations could face more restrictions and testing in the near future.

The Board of Animal Health announced on Feb. 4 that cattle from a Roseau County cattle operation tested positive for bovine Tuberculosis (TB).

This particular herd tested negative in 2005 and 2006, but during a third round of testing, TB was confirmed in two animals.

"We've had the 10th herd come up positive for TB," said Ryan Walker, University of Minnesota Extension beef team member.

  

Walker spoke to producers attending Cow/Calf Days held across the state in mid-February. He encouraged producers to call the Minnesota TB Hotline at 1-877-668-2373 with any questions.

"If you are planning on breeding cattle, selling cattle or going to any shows (outside of Minnesota) in the next two or three months, call this TB Hotline," Walker said. "Find out the TB testing requirements based on where you're going." Minnesota Board of Animal Health Executive Director and State Veterinarian Dr. Bill Hartmann said if another infected herd is found, Minnesota's TB status might be downgraded.
  

"Conversations are ongoing with USDA about Minnesota's future TB status should we find one more herd," said Hartmann in a news release. "It's important that we prepare for all possibilities and unfortunately, one scenario would see the downgrading of our state from Modified Accredited Advanced to Modified Accredited." Federal interstate movement requirements would change with the status.

States also have the option of setting their own requirements for cattle imports.

The current status, Modified Accredited Advanced, places no restrictions on feeder cattle or bison, requires a TB test within 60 days of movement for breeding cattle or bison, and requires no test for slaughter cattle or bison that are moving directly to slaughter at an approved slaughter facility.

Modified Accredited status is more stringent and expensive.

Feeder cattle or bison need a negative TB test within 60 days of shipment.

Breeding animals need a negative whole herd TB test within 12 months of shipment plus a negative individual animal TB test within 60 days. A TB test will not be required for bison or cattle going to slaughter.

Dairy operations are also affected. Should Minnesota drop to the Modified Accredited status, milk herds will have to obtain annual negative TB herd tests or earn an accredited herd status. Dairy farms could also participate in a state surveillance program.

Determining Minnesota's TB status has become a counting issue.

USDA keeps status levels for TB based on how many herds are found during a given fiscal year.

The fiscal year for USDA starts in October and ends in September.

So far, three herds have tested positive for TB in the current fiscal year.

A fourth herd could mean a drop in status.

"We may or may not get another herd of TB finding, but we're close enough that maybe producers need to think about their options," said Ted Radintz, Minnesota Department of Agriculture outreach coordinator.

The Minnesota Board of Animal Health is planning meetings for cattle producers throughout the state to present information on the chronic respiratory disease.

Meetings will be held Feb. 25 at the Lewiston Auction Market (morning) and the Pipestone Auction Market (afternoon). Meetings will be held Feb. 26 at the Melrose City Center (morning) and the Grygla High School (afternoon). A meeting will be held Feb. 27 at the Northland Community & Technical College at Thief River Falls.

More details will be published soon.

Over 1,500 Minnesota cattle herds have tested negative for bovine tuberculosis as part of the Minnesota Bovine TB Surveillance program. An additional 326 herds were tested as part of the state's disease investigation and area testing efforts. Testing continues in northwestern Minnesota where the disease has been found.

The Minnesota Farmers Union Board of Directors voted in early February to support a split-state bovine TB status that would separate the treatment of the impacted area of Minnesota from the portion of the state not affected by TB.

The newly detected beef herd was located close to a herd that had tested positive for TB in 2005.

The Minnesota Board of Animal Health says that exposure to bovine TB by the general public is very unlikely. Meat inspectors check all cattle entering the market for signs of the disease before and after slaughter. Any animals showing signs are withheld from the food supply. In addition, adequate cooking destroys the TB bacteria.
