Regular Bovine TB Outbreaks in the UK and Overseas - even in Areas officially declared to be TB Free



 Added by  Sally
 15 Jul 2010, 3:38 PM


Whilst the UK (and many other developed countries), strive to eradicate bovine TB, the battle is regularly lost in many areas with regular outbreaks in areas declared to be TB free. The international standard for TB freedom is reached when 99.8 per cent of domestic cattle and deer herds have been free for three years and this is similar for the EU. An impossible task with increasing globalisation and when one considers that around 85% of cattle and 82% of the human population are in areas where bovine TB is either only partially controlled or not controlled at all ('Zoonotic tuberculosis due to Mycobacterium bovis in developing countries.').
 
This s demonstrated in the following web links which reveal the number of breakdowns in different areas over the last few weeks and the current situation in other areas. We hope to add to these links on a regular basis.
 
Reports are from July 2010 onwards.

But the board still has some way to go before achieving its aim of New Zealand being considered free of bovine TB. It aims to be TB free by 2013.

Ohio Department of Agriculture Director Robert Boggs today announces that preliminary tests performed by the department’s Animal Disease Diagnostic Laboratory revealed a positive result for bovine tuberculosis in a Paulding County dairy herd.
 
http://www.agrinews.com/most/minnesota/cattle/no/longer/need/tb/test/to/go/to/north/dakota/story-2702.html The state's animal health board voted June 23 to immediately revoke an order that required negative TB tests on cattle, bison, goats, farmed cervids and camelids. The lifted requirements apply to Minnesota's Modified Accredited Advanced zone, the majority of the state.

http://www.cattlenetwork.com/What-Does-Discovery-Of-Bovine-Tuberculosis-In-A-Herd-In-Ohio-Mean-For-Ohio-Livestock-Farmers/2010-0...
In July 2010 a dairy herd had recently been detected with bovine tuberculosis (bTB) and subsequently depopulated. There have apparently been similar outbreaks in other states.Biosecurity and the concern of introducing diseases, like tuberculosis and others characterized by 'silent'" infections, into herds and flocks is mentioned. Should additional herds be discovered in the next two years, the possibility of loss of the existing 'free" status' with respect to bTB exists. The current situation in Ohio and the USA, with respect to bTB, is interesting and gives some insight into changes that have occurred over the past 20-30 years. Herd size has tended to increase, especially in the dairy industry. Some of this expansion occurred with retention of natural additions to herds, but for many herds it also involved movement of animals from one herd to another. In some cases bTB has been traced to Mexican cattle entering the US as Holstein feeder animals and roping/rodeo steers. Unfortunately, in a few cases contact between these animals and other animals destined for breeding herds has occurred. This time frame has also seen the growth of farmed deer, elk, and bison herds, much of which was unregulated until recent years and in which some level of bTB may have persisted. The conspicuous feature of this change is the nature and amount of animal movement.

July 7, 2010, press release from the Ohio Department of Agriculture announced that a dairy herd had recently been detected with bovine tuberculosis and subsequently depopulated. Should additional herds be discovered in the next two years, the possibility of loss of our 'free' status with respect to bTB exists. This could have a profound impact on Ohio farmers.

A second Emmet County farm has been classified as being infected with bovine tuberculosis in Michigan. State officials say a first herd tested positive in March. An investigation found that a breeding bull from that herd had been leased to the second Emmet County producer. Emmet County is in a zone where herds must be tested at least once every three years and sometimes more often, depending on the type of cattle sold.

The incident dates back to April when one of the animals appeared to have vesicles, revealed during a routine inspection at the abattoir. However, it took several weeks before the authorities could definitively say it concerned bovine TB. In France, an average of thirty cases of the disease is detected per year.

In south west France a new case of bovine tuberculosis has been found. It is the third contaminated farm in this region.
The 500 animals on the farm will be culled, according to local veterinary services. The first case of bovine TB was in Ariège (see previous), close to the Spanish border. A few days later, a second case of the disease was found in the same area. A total of 110 cows have been culled on both farms. Around 30 farms are under quarantine now. Tests at nine suspected farms appeared to be negative.
 
 
http://www.kdvr.com/lifestyle/sns-ap-co--cowquarantine,0,7856508.story The cows were diagnosed with TB in April. Tests showed a "significant level" of infection within the 500-cow southern Colorado herd, which were all slaughtered.

MICHIGAN More bovine TB — and more cattle will be destroyed. Another Holstein steer has tested positive for bovine TB in Huron County — the second to be affected by the disease in less than two months.
A large dairy lot in the eastern part of the county has been quarantined by the Michigan Department of Agriculture and Rural Development (MDA) after slaughterhouse surveillance confirmed the steer was bovine TB-positive on April 4. It is expected the steer came from a Saginaw County feedlot quarantined in March of last year, making it the second occurrence in Huron County since Feb. 10.
 
If the steer did not originate from the Saginaw herd, or any other infected herd the MDA has knowledge of, it would be considered a new outbreak and could impact the TB-free status in the southern part of the state. The owner has agreed to sell all animals on the infected lot. They will then be sent directly to a slaughterhouse. The majority of cattle would have been ready for slaughter in the next couple months, he said.
The incident will be “fairly well mitigated” by the fact that the producer will be able to finish feeding and send the cattle to slaughter.
 
A family-run farm in Fairhaven Township remains under quarantine after inspectors discovered a two-year-old steer tested positive for bovine TB on Feb. 10. A three-mile radius has been drawn for surveillance testing, with the lot at the center, to see if the disease has affected area farms.
It was the first incident in the county for “at least 40, if not 50 years,” Dr. James Averill, state veterinarian and division director for MDA’s animal industry, said. “This newest feedlot is likely the fifth herd tied back to the Saginaw dairy farm,” he said.
 
Bovine TB outbreaks have frequented an 11-county zone in northeastern Michigan since the ’90s when the disease re-emerged.
 
“It dramatically affected everything there — the business, tourism, everything,” he said, adding that the “state is right on top of” handling the situation.
 
Two incidences have now surfaced in Huron County, while Midland, Gratiot and Arenac counties also have reported cattle testing positive for bovine TB stemming from the Saginaw lot.
 
Averill said beef is safe to eat and animals that have lesions suggestive of bovine TB are pulled and do not enter the food supply. “There’s no food safety issue her for consumers,” he said.

CANADA Manitoba Beef Producers is welcoming nearly $300 thousand in federal funding to help track and eliminate bovine tuberculosis in the Riding Mountain TB Eradication Area.
 
The funding announcement by Dauphin-Swan River-Marquette MP Robert Sopuck on April 23rd came just a few weeks after the Manitoba government also said it's giving MBP $150 thousand to improve tracking of the disease.
 
"Basically the dollars from this project will support better tools needed for surveillance, and with that we're hoping we will have a reduction in live animal testing and eventually a move toward eradication," explains MBP general manager Melinda German.

NEW ZEALAND Only one bovine tuberculosis (TB) infected herd remains in Northland after the disease was cleared from six herds.The single, remaining infected herd has recently had a whole herd TB test and is also on the verge of being cleared of the disease. The six other herds were linked by stock movements made before the disease was diagnosed.
 
National Animal Identification and Tracing (NAIT) data was vital in helping to rapidly trace movements of animals from the original infected herd, ensuring properties were put on a strict testing regime and any TB-infected cattle were sent to slaughter.
 
As a precautionary measure, contractors also trapped wild animals in the area to check for the disease in wildlife populations, particularly possums. Nearly 1400 possums had a post mortem, with no indication that the disease has spread to wildlife in Northland. (It is appalling that that in the UK the Government culls badgers and does not even bother to test them for bTB.)

NEW ZEALAND Dairy herds in Taranaki infected with bovine tuberculosis as previous postings. According to a report in the Central South Island Farmer on 25 September 2013 stock purchases have now been been identified as the source of this year's infection (outbreak in six herds). A TB Free New Zealand spokesperson said it was confident the Inglewood infections were as a result of the purchase of stock as it has not been found in wildlife in the area. So, yet another example of movement problems and inadequate tests.

ARENAC COUNTYv USA A case of bovine tuberculosis (TB) was reported in Arenac County by the National Veterinary Services Laboratory Sept. 5, according to Northeast Michigan Extension dairy expert Phil Durst.
 
Durst said the TB was found in a dairy heifer in a herd of cattle that was being prepared for slaughter. He said currently, he does not know the farm or location within the county where the TB was discovered.
 
Because of the presence of TB, farms in the surrounding area can expect testing by the U.S. Department of Agriculture in the near future.
 
“They will do both circle testing and trace testing from this herd,” he said. “Circle testing is when they will draw a three-mile radius around this herd, and test any herd that falls within this area. Producers don’t have to know where the original herd is, because they will be contacted.”
 
Trace testing, Durst added, is when the herds the infected animal formerly belonged to are tested. Because this animal was being slaughtered, herds in its location history will be tested, he said. According to Durst, it is believed the infected heifer was also housed in Saginaw and Gratiot counties.

SWITZERLAND Switzerland was free of the disease for 50 years before a surprise outbreak in the canton of Fribourg last year. Recently 7,000 cattle were tested in 15 cantons leading to 200 being destroyed.
 
Nathalie Rochat from Bvet, the Federal Veterinary Office, says tracing the source of the disease presents numerous problems.
 
“It’s a great challenge. As soon as an animal is tested positive, every other animal it has been in contact with has to be traced. And that can lead to entire herds being tested. The situation isn’t under control but it’s stable.”

NEW ZEALAND In the UK this country is held up as an example to follow (possums are culled) yet outbreaks are frequent. Six more herds have been identified as infected in the Northland's region. Those herds were linked to the movement of stock off a farm that was found to be infected late last year.
 
Routine tracing of all stock movements from the TB-infected herds was on-going, TBfree Northland committee chairman Neil MacMillan said, and the infected animals from all seven properties had been sent to slaughter.
 
Cattle over 12 months of age within a 10- to 15-kilometre radius of Kaitaia had been placed on an annual testing programme, and cattle Tb testing contractors were now working to identify any signs of the disease in other herds. Checks for Tb were also taking place at meat processing plants.

NORTH DAKOTA. TEXAS A beef cow in south central North Dakota that originated in Texas has tested positive for bovine tuberculosis in initial tests. The animal was identified as a result of a trace-out investigation in Texas.
 
State animal health officials say the cow has been removed from the herd and killed. Results of additional testing are expected within two months. Officials say there is no immediate health risk to the general public.
 
North Dakota has been recognized by the federal government as being TB-free since 1976. A state must have at least two herds test positive for the disease within two years to lose that status.
 
The state’s last reported case of bovine tuberculosis in a herd was in 1999.

Updated 23/8/13
 
BISMARCK, ND - State Veterinarian Susan Keller says field and laboratory testing indicates that bovine tuberculosis found in a beef cow in south central North Dakota hasn't spread to other animals.
 
The state Board of Animal Health reported in mid-June that a cow in a herd near Solen had tested positive for bovine TB, a potentially fatal disease that spreads through inhaled bacteria. The cow had come from Texas and moved through a seller in South Dakota.
 
Keller says 33 other suspect animals in the herd were killed as a precaution. They're still being tested at a laboratory but Keller says the preliminary report shows nothing suspicious.
 
The remaining animals in the herd are undergoing further testing to meet federal requirements. If no additional bovine TB is found, a quarantine will be lifted.

MICHIGAN The Michigan Department of Agriculture and Rural Development says that offspring purchased from a bovine tuberculosis (TB) positive Saginaw County dairy farm, and traced to farms in Midland and Gratiot counties, are also TB positive.
 
In March, a Saginaw County dairy farm was discovered to be bovine TB positive when a cull cow with lesions went to slaughter. U.S. Department of Agriculture (USDA) Food Safety Inspection Service examiners removed the cow and sent it for laboratory testing. As part of its bovine TB response plan, MDARD quarantined the farm and immediately started an investigation into where any deacon calves (bull calves from dairy cows, usually raised for beef) or heifers may have gone.
 
The search found two small beef herds: one in Midland County and another in Gratiot County, both raising deacon calves from the affected Saginaw County herd. Cattle with a skin test response were euthanized and submitted to Michigan State University’s Diagnostic Center for Population and Animal Health for laboratory examination. Tissue samples were then sent to the National Veterinary Services Laboratories in Ames, Iowa, which reported the animals were positive for bovine TB.
 
MDARD will now bovine TB test cattle in two additional special surveillance areas in 10-mile circles around these two farms. Cattle producers will be notified directly by MDARD if they lie within the 10-mile circles. Those contacted will also be given an opportunity to request disease control permits to remove deer as part of the Michigan Department of Natural Resources’ disease surveillance effort in these circles.

UPDATE ADDED 15/5/13
Two cows suspected to be TB-positive were discovered during routine annual testing of an Alcona County cattle herd in February. After dissecting both cows, one was found to have a lesion in a lymph node in its throat. DNA tests confirmed it was bovine TB.
 
The infected herd, the 57th discovered since 1998, has since been depopulated, Smith said. The United States Department of Agriculture reached this decision after consulting with the farmer, who was compensated for the cows. The farm is in what's known as a modified accredited zone, so no additional testing of nearby farms is required.
 
Wildlife biologists are now checking animals they caught on the farm for TB, Smith said, adding it's uncertain whether small mammals contribute to spreading the disease. The bacteria is slow-growing, and can sit dormant in an animal for years, so it's extremely difficult to research just how it's spread.

NEW ZEALAND - often held up as an example but they do STILL have bTB as the report at www.stuff.co.nz/taranaki-daily-news/news/8621718/Annual-bovine-TB-tests-loom-in-Taranaki reveals. Annual testing for bovine tuberculosis (TB) is to be introduced on nearly 750 Taranaki properties this year.
 
The new regime of testing animals more than 12 months old follows the TB outbreak which has infected four dairy herds near Egmont Village and two near Pihama.
 
Until now TB testing has been undertaken every three years on Taranaki cattle and deer more than two years old.
 
Animal Health Board (AHB) North Island regional co-ordinator Frank Pavitt said animals on 555 farms and lifestyle blocks within a 10-kilometre radius of Egmont Village and 192 properties within 10km of Pihama would now be tested annually.
 
Animals due for testing next year or in 2015 would now be tested this year where practical, he said. Those already tested this year would not need to be tested until next year.
 
Mr Pavitt hopes farmers will see the increased programme of testing as a benefit rather than a burden.
 
He is appealing to owners of cattle and deer in Taranaki to make sure they register their animals with the AHB to protect their own and their families' health and lifestyle.
 
Mr McIntyre said the outbreak showed the need to register animals and complete animal status declaration forms so animal movements could be traced.

EUROPE A report of a technical meeting of the EFSA Scientific Network for Risk assessment in Animal Health and Welfare - Bovine Tuberculosis Testing
Parma held 21 February 20121 can be found at: http://www.efsa.europa.eu/en/efsajournal/doc/288e.pdf
 
Included is the bTB status for several EU countries, including the UK, The Netherlands, Poland, Germany, Spain, Ireland, France,  Hungary, Italy and  Belgium .
 
SUMMARY
The Animal Health and Animal Welfare (AHAW) scientific network was created in 2009 with the aim to facilitate scientific cooperation in the field of the EFSA’s mission by coordinating activities, exchanging information, developing and implementing joint projects, exchanging expertise and best practices. During the AHAW scientific network meeting, in November 2011, the subject of bovine tuberculosis (TB) and in particular diagnostic testing for the purpose of disease control and
demonstration of freedom was identified as of common interest. A technical meeting was organised with the objective of sharing information about bovine TB and bovine TB testing data and to assist
EFSA in collecting information relevant to future mandates.
 
Representatives from 10 Member States participated in the meeting. Based on the experts presentations a summary of the information
concerning the official status on Bovine TB infection of each country and bovine TB testing and surveillance was made. There is large variation on the test and testing protocols used in different MS. These variations refer to the use of both the official bovine TB diagnostic test (tuberculin skin tests) and the ancillary test (IFN-γ BA test) but also and more important on the objectives to achieve. These variations can affect the diagnostic tests accuracy. The different tests and testing protocols are not
adequately described resulting in surveillance data that are difficult to validate and compare. The meeting provided an overview of the issues on the disease surveillance and control and gave the opportunity to identify areas of future collaboration.

SAGINAW COUNTY, MI (WNEM) -
There are concerns and questions about some Mid-Michigan livestock after an entire herd tested positive for bovine tuberculosis.
 
And the discovery has Saginaw County beef and cattle farmers are worried about their livestock and, in turn, their livelihood.
 
"I have a nice small herd of cattle that's important to my family as well as my children, and also the folks that buy beef from me," said local farmer Scott Peters.
 
The discovery of bovine tuberculosis in a Saginaw County dairy cow herd is almost unheard of. That concern is why the state's department of agriculture and rural development held an informational session for beef and cattle producers.
 
Scott Peters says his farm is TB free, but he says he plans to test his herd anyway. "I want to be able to assure them that they're getting a good quality product free from of any disease," said Peters.
 
Meanwhile, state officials are preparing to begin testing next week of 66 herds within a 10-mile radius around the farm first discovered to have infected cattle.
 
At a meeting held Monday night between the Michigan Department of Natural Resources and the Michigan Department of Agriculture, it was decided that deer hunting season will open early for hunters within a 10-mile radius of the affected farm.
 
Farmers in the area have received applications for special deer hunting permits and will be able to keep deer after they are tested by the Department of Natural Resources.

UPDATED 6/4/13:
A herd of cows has been euthanized in the canton of Fribourg, after it was found that most were infected with bovine tuberculosis.
 
The herd was tested after one cow became seriously ill last month.
 
Neuchâtel’s Department of Food Safety and Veterinary Affairs says the testing showed that the herd had “a high rate of infection” and decided to euthanize and incinerate all of the animals.
 
The health officials say the high rate indicates that the tuberculosis was present for years, and that cows which tested negative could have in fact been carrying the infectious agent.
 
Infected animals have also been found in cantons Vaud and Valais. Further tests are taking place.

Look at the lengths Texas went to re 'eradicating' bTB - banning dairy farms in the area! Read the interesting article at:www.nytimes.com/2013/02/22/us/texas-lawmaker-seeks-end-of-dairy-farm-ban-in-el-paso-county.html?_r=0
 
In 2003, the U.S.D.A., the Texas Animal Health Commission and El Paso dairy farmers agreed to an estimated $44 million deal to buy out 11 dairies in El Paso, eradicate the cattle and isolate the farmland for 20 years. In 2006, Texas regained its bovine tuberculosis-free status.
 
Dairy farmers are now trying to get ban lifted.

www.foodsafetynews.com/2013/02/investigation-underway-for-bovine-tuberculosis-case-in-ca/ More about the California bTB outbreaks. Interesting extract below.
 
In an email to associates in veterinary science and epidemiology, California State Veterinarian Annette Jones said that this most recent case was most likely not associated with multiple cases of bovine TB discovered in San Bernardino County dairy cows throughout 2011.
 
“We are just beginning to look into how this TB case was introduced and if it has spread — testing for TB is a long and arduous task with less than perfect tests at our disposal,” Jones wrote, “so it may be weeks to months before we have additional information to share.”

WASHINGTON Washington state agriculture officials are investigating a possible case of bovine tuberculosis in a Grant County dairy cow sent to slaughter. bTB has not been seen in Washington cattle since 1988.
 
Agriculture Department spokesman Hector Castro said Thursday that the meat was isolated after a federal food safety inspector spotted a suspicious lesion and sent a sample for testing. The cow was sent earlier this month to a Cowlitz County slaughter facility.
 
Castro says milk produced by the dairy was intended for pasteurization, which kills bacteria, including bovine TB. The dairy was not identified.
 
The National Veterinary Services Laboratory in Iowa reported Wednesday that the tissue sample was consistent with bovine TB. Castro says an additional test is being done to confirm the diagnosis, with results expected in six weeks.
 
The meat was destroyed.

UPDATE
Federal agriculture officials did not find any evidence of tuberculosis in the cattle at the cow’s former dairy, located in Snohomish County, WSDA communications director Hector Castro told Food Safety News. A team of seven veterinarians from the WSDA and the U.S. Department of Agriculture first tested the farm’s 20 dairy cows, and then the remainder of the farm’s cattle — roughly 300 heads — which are kept separately from the dairy cows.
 
Now the investigation has turned to the Grant County dairy that most recently owned the cow. Investigators completed the first phase of testing that herd, which involves injecting each cow with an antigen that produces a bump on the skin. Investigators will wait 72 hours before returning on Monday to check for any cattle that might still have the bump, which would suggest a tuberculosis infection.

The government typically either slaughters the entire herd or tests them for potential reaction, removing those that show initial signs for further testing, Jonker said. The latter practice takes longer, but allows the farmer to keep animals that are free of disease.
 
It takes daily doses of antibiotics for six months to a year to cure an infected human or animal, Schmitt said.
 
FURTHER UPDATE
As of Jan 29 an investigator from the USDA and the Washington State Dept of Agriculture declared the dairy farm near Monroe clear of bovine tubercolosis. Tracing back from a positive TB result from a cow at a Cowlitz County slaughter facility led to this dairy and about a dozen other herds in Washington and Idaho, which will also be examined.
 
The cow was from a Moses Lake dairy and had been bought from the Monroe dairy about a year ago. Cattle at the Moses Lake dairy and elsewhere are still being tested. State health officials say there’s no immediate human health concern connected to the suspected bovine TB case. The meat from the infected cow was isolated until the test results came back.

Then 30 Jan media coverage stating that eleven more cows have tested positive for bovine tuberculosis (T-B) at a dairy which produced the first TB infected cow in Washington state in 25 years.
 
State agriculture veterinarians tested 1,350 at the dairy and say the 11 positive results were lower than expected. Spokesman Hector Castro said these are only initial tests and the 11 cows will be removed from the herd pending further testing. He said in most cases at least one to four percent of the cows in a herd where an infected cow is discovered test positive. A cow from that same dairy tested positive earlier this month at a slaughter house.
 
Castro said the infected cow initially came from a dairy in Snohomish County. All the cows at that dairy tested negative. Cows at an operation near the Moses Lake dairy also were also tested and came back T-B free. Castro said there will be more tests over the next several months.

ALPENA COUNTY A dairy herd in Alpena County has tested positive for bovine Tuberculosis, the Michigan Department of Agriculture and Rural Development says.
 
Routine bovine Tuberculosis surveillance testing confirmed the medium size dairty herd as 'bovine TB positive.'
 
Since the bovine TB eradication effort began, all of Michigan's 14,000 cattle farms have undergone TB testing. Since 1998, MDARD and the USDA have detected 55 TB positive cattle herds and four privately owned cervid operations in the northern section of Michigan's Lower Peninsula.

New Zealand has been spraying more poison from the area over great tracts of land in an effort to kill possums, believed to be the wildlife reservoir of bTB in New Zealand. The Animal Health Board (AHB) has recently completed the latest aerial possum control operations on the West Coast.
 
The aerial operations, using biodegradable sodium fluoroacetate (1080), support an extensive programme of ground-based control work which uses a combination of hand-laid toxins and traps. Apparently aerial control is necessary in some areas because of the difficult terrain - it is, we are told, quicker and more accurate.
 
Following the operations, public tracks were checked, and water samples were taken as required by the local medical officer of health. All apparently came back clear of 1080. The samples were extracted by an independent company and analysed by Landcare Research.
 
Warning signs were erected before the operation and are regularly checked to ensure they remain in place. The public are urged to carefully follow the instructions on these signs, which are placed at each major public access point to the operational areas.
 
It is the owner’s responsibility to keep their dog well away from any operational areas until all warning signs have been officially removed.
