The Montana Department of Livestock has adopted changes to rules affecting vaccination requirements

The newly adopted brucellosis vaccination rule (ARM 32.3.433) mandates that eligible animals in 10 Montana counties must be vaccinated against brucellosis. The change requires that all sexually intact female cattle and domestic bison 12 months of age or older in Beaverhead, Big Horn, Broadwater, Carbon, Gallatin, Jefferson, Madison, Park, Stillwater, and Sweet Grass Counties must be brucellosis vaccinates. Prior to this rulemaking, only cattle and domestic bison in Gallatin, Madison, Park, and Beaverhead Counties were required to be vaccinated.  This rule includes cattle that enter any of these counties for seasonal grazing.

Beyond the addition of new counties, the rule also moves away from December 1st as the cutoff date for completion of vaccination and no longer specifies that animals be calf-hood vaccinates. This gives producers more options for the management of replacement heifers and allows animals to be vaccinated as adults.

“Vaccination in a broader area than Montana’s DSA provides some protection from sudden changes to the distribution of infected wildlife on the landscape,” said Eric Liska, brucellosis program veterinarian with MDOL. “Vaccination has been shown to minimize the spread of the disease if it is introduced into a livestock herd.”

Producers who have not vaccinated their replacement females in the past should contact their local veterinarian to schedule replacement heifer vaccinations and discuss options for unvaccinated adult females in the herd.

Additionally, changes to ARM 32.3.433 adjusts the DSA boundary in a portion of Beaverhead County. Cattle and domestic bison that utilize this area will be subject to all brucellosis DSA regulations. DSA regulations include brucellosis testing prior to a change of ownership and movement as well as vaccination and identification requirements.

The DSA boundary has expanded 3 times since 2009. Each expansion was made in response to findings of brucellosis in elk which required the inclusion of additional cattle and domestic bison in the surveillance program. The undetected disease spread outside of Montana’s DSA could jeopardize Montana’s federal brucellosis Class Free status, and in 2008, a loss of brucellosis Class Free status was estimated to have cost Montana’s producers up to $11.5 million annually.  DSA regulations and producer compliance have allowed for early disease detection when a periodic transmission from wildlife to livestock does occur. This success promotes trading partner confidence in the disease-free status of Montana’s livestock.

First Confirmed Equine Case of West Nile Virus in Montana for 2018

Helena, Mont. – The Montana Department of Livestock has received the first reported cases of equine West Nile Virus in Montana for 2018 in Musselshell and Lake Counties. This follows the detection of the virus in mosquito surveillance pools from Cascade, Hill, and Lewis and Clark Counties. Montana typically sees cases of West Nile Virus through late summer and into fall.

West Nile Virus affects humans, equines, and birds. It is spread through the bites of infected mosquitos; horses cannot transmit the virus directly to people. Detections of the disease in horses and mosquitos in Montana serve as an important reminder for people to take steps to prevent West Nile Virus infection.

“There is no direct treatment for the virus in horses, but vaccination is highly effective in preventing disease. Horses that are vaccinated rarely die or are euthanized because of the disease,” said Dr. Tahnee Szymanski, Assistant State Veterinarian.  “Vaccination is typically administered in the spring but may offer some protection even this late in the season. Work with your veterinarian to determine if your horse could still benefit from vaccination.”

Horse owners should be aware of the typical signs of West Nile Virus which include:

  • Fever, loss of appetite and depression;
  • Incoordination or weakness of the hind limbs;
  • Muscle or muzzle twitching, drooling.

In the meantime, topical insecticides and eliminating standing water may help decrease your horse’s exposure to mosquitos. The mosquitos that carry West Nile Virus are most active at dawn and dusk, so consider keeping your horses off of irrigated pastures and away from water sources during those times of the day.

Montana to Exercise Animal Disease Response

The Montana Department of Livestock (MDOL) is collaborating with the United States Department of Agriculture (USDA) and other state and local agencies to conduct an animal disease response exercise, May 8-10, 2018.

The three-day functional exercise will enable MDOL to practice the state’s animal disease response plan. Numerous federal, state and local government agencies will participate in the exercise, which will be based on an outbreak of foot-and-mouth disease (FMD) in the United States.

“Foot-and-mouth disease would have devastating consequences for Montana’s livestock industry and how we handle the initial response would be crucial,” said State Veterinarian Marty Zaluski. “Testing our response plan in an exercise format will be very beneficial and we look forward to participating in the exercise.”

Foot-and-mouth disease was last identified in the United States in 1929. FMD is a highly contagious disease of cattle, sheep, swine, goats, deer and other cloven-hooved animals. It is not a human food safety concern nor a public health threat; however, it is a major concern for animal health officials because it could have potentially devastating economic consequences due to disrupted trade and lost investor confidence. Montana is home to over 2.5 million head of cattle which bring around $1 billion each year in cash receipts.

“This exercise will be a positive experience that will make Montana’s livestock industry more resilient and better prepare us for an outbreak,” said MDOL Executive Officer Mike Honeycutt. “The public should not be concerned if they hear anything about foot-and-mouth disease during the days of the exercise.”

Montana Department of Livestock investigates TB in S.D. herd

Helena, Mont. – The Department of Livestock (DOL) is investigating ties to Montana cattle from a tuberculosis (TB) infected herd in South Dakota. Montana is focusing on three distinct groups of animals:  Contact herds – herds that have shared pasture or fence line contact with the affected herd; Herds that have supplied animals to the affected herd; and Herds that have received animals from the affected herd.

At this time, two Montana cattle herds that had contact with the South Dakota positive animals must undergo a tuberculosis test to confirm that the disease has not spread. Additional herds may be identified as the investigation progresses. The likelihood that Montana herds are infected is extremely low, however, the department is conducting a thorough investigation.

“Following up on interstate movements after a detection of TB or other animal disease is a routine part of disease investigations,” said Tahnee Szymanski, Assistant State Veterinarian. “Our strong working relationship with South Dakota is critical in promptly identifying animal movements and protecting the state of Montana.”

Bovine TB is caused by the bacteria Mycobacterium bovis. The disease causes granulomatous lesions inside the lymph nodes, lungs, liver, spleen, and skin of affected animals. The primary route of spread is aerosol transmission to other animals in close contact. The bacteria is also capable of infecting wildlife, such as deer, and people. The disease has an incubation period that can range from months to years and infected animals may show no clinical signs until later stages of infection, meaning healthy appearing cattle may be infected with the bacteria.

Although TB is a zoonotic disease capable of infecting people, it is not a food safety threat, thanks to a robust meat inspection program and the pasteurization of milk for retail sale.

The mission of the DOL is to control and eradicate animal diseases, prevent the transmission of animal diseases to humans, and to protect the livestock industry from theft and predatory animals. For more information on the department, visit www.liv.mt.gov.

Department of Livestock Keeps Watchful Eye on Canadian Tuberculosis Cases

The Montana Department of Livestock (DOL) is actively monitoring the bovine tuberculosis (TB) investigation in Canada. In late September, the Canadian Food Inspection Agency (CFIA) initiated an epidemiological investigation after bovine TB was detected in a Canadian cow at a United States (US) slaughter facility.

As of December 2, 2016, there are six confirmed cases of bovine TB in Canada, including the index animal detected at slaughter in the US. Of the roughly 40 premises currently under quarantine, most are located in Southeast Alberta with about five premises in Saskatchewan. DOL has long standing requirements that cattle coming from Canada need to be tested for TB prior to import.

“Despite what feels like close proximity of this incident, Montana cattle producers remain safe,” said Montana State Veterinarian, Marty Zaluski. “Canada’s vigorous response, combined with our requirement that Canadian cattle be TB tested before entering Montana, keeps the risk low for ranchers in the state.”

Zaluski is not planning to place additional requirements on Canadian cattle coming to Montana at this time. “I am closely monitoring CFIA’s efforts and am ready to act aggressively if needed,” said Zaluski.

Historically, DOL has recognized the efforts of other state and provincial animal health officials to effectively deal with disease events, and expects the same in return.

CFIA policy requires that all positive animals and any animals exposed to positive animals be humanely destroyed. All exposed animals will be tested first and those that test negative will be eligible to enter the food supply. At this time approximately 10,000 cattle are to be destroyed. The strain of TB identified in the index case closely resembles a strain associated with cattle in Central Mexico, suggesting that wildlife are an unlikely source.

The mission of the DOL is to control and eradicate animal diseases, prevent the transmission of animal diseases to humans, and to protect the livestock industry from theft and predatory animals. For more information on the department, visit www.liv.mt.gov.

MSGA has been closely monitoring the recent TB outbreak in Canada. We have corresponded with State Veterinarian, Dr. Martin Zaluski, DVM and the Montana Congressional Delegation in D.C.. We are feeling confident at this time, that Canada’s aggressive response to the outbreak is the right approach and that Montana’s cattle herd should not be impacted.

Governor’s bison plan OK’d; will reduce hazing near Yellowstone

Source: Bozeman Daily Chronicle

WEST YELLOWSTONE — State, federal and tribal agencies agreed on Wednesday to adopt the governor’s plan to allow some bison to stay in Montana year-round, a move officials say will reduce bison hazing done each year near West Yellowstone.

The change will let a certain number of bison stay year-round on Horse Butte near West Yellowstone and north to the Buck Creek drainage, located just south of Big Sky, without being chased back into Yellowstone National Park. The decision also calls for year-round tolerance for male bison north of Gardiner into Yankee Jim Canyon.

At an Interagency Bison Management Plan meeting here, none of the tribal or federal agencies objected to the governor’s December decision, meaning the plan has essentially been approved.

“This a day to be celebrated,” said Montana Fish, Wildlife and Parks regional supervisor Sam Sheppard.

The change comes as an amendment to the 2000 Interagency Bison Management Plan, which specifies procedures and population goals for the nearly 5,000 bison that live in the Yellowstone region.

Some tolerance for the animals had already existed outside of the park, but the governor’s decision adds significantly more land to the tolerance zone on the west side, where bison had been hazed back each year.

The decision sets seasonal limits on the number of bison allowed to remain west of the park — 450 from September through February, 600 from March through June, 250 in July and August. When bison numbers exceed that, the state could chase them back across into Yellowstone.

Those figures reflect the number of bison officials expect to see outside of the park in each season. They expect many of the bison that come out in the spring will migrate back into Yellowstone on their own before July, meaning they wouldn’t need to be hazed. Sheppard said the decision “allows bison to do the work for us.”

The decision doesn’t eliminate hazing. Bison still won’t be allowed near the South Fork of the Madison River, so after May 15 they will be chased to either the tolerance zone border or the park border, whichever is closer.

Hazing would still happen on the north side of Yellowstone each year, starting May 1. The decision only allows male bison to roam north to Yankee Jim Canyon year-round, not females.

Female bison raise concerns for livestock producers during the spring calving season because of the disease brucellosis, which can cause cattle to miscarry. The disease is transmitted through afterbirth, and more than half of Yellowstone’s female bison are believed to have been exposed to it. No case of bison transmitting the disease in the wild has been documented.

Still, hazing is one way the IBMP tries to eliminate the risk of disease transmission.

Montana Department of Livestock state veterinarian Marty Zaluski said if there is a mixed group of male and female bison that are in that area, officials won’t attempt to sort the male bison out.

“If there’s a mixed group, then that group will go back,” Zaluski said.

“We’re not in the business of sorting bison,” added Rob Tierney, bison program manager for the Department of Livestock.

Sheppard said that by that time, most bison have usually left the Gardiner Basin for lands inside the park anyway.

Tom MacDonald, fish and wildlife division manager of the Confederated Salish and Kootenai Tribes, said the plan to expand tolerance was a “logical step forward in managing bison.”

Environmental groups and buffalo advocates were pleased with the partner agencies giving the plan a thumbs up Wednesday. During the public comment portion of the meeting, representatives of a few groups thanked the IBMP partner agencies. But it isn’t the end of the fight for them.

“We hope this decision drives further advancements for Yellowstone bison, which unfortunately continue to be shipped to slaughter when they leave the park in search of food in the winter,” Stephanie Adams of the National Parks Conservation Association said in a statement.

On the other side, Jay Bodner, natural resource director for the Montana Stockgrowers Association, said his group still opposes the governor’s decision. He said they worry that budgets for FWP and the Department of Livestock will be stressed by increasing how much land bison can use since it might require more on-the-ground work. He is also concerned that government officials will ask for even more tolerance in Montana, rather than reducing the number of bison in the region.

“I don’t think our concerns have been addressed,” Bodner said in an interview.

The agencies involved are currently working on a new Interagency Bison Management Plan, and a draft is expected out sometime this year.

Over the next few days, the current plan will be amended to include the governor’s proposals. Each agency involved is expected to formally sign off on the changes later this month, after which the document will be posted online.
