Defra advice on bovine TB ‘futile’

Defra advice on bovine TB ‘futile’
Wednesday, April 29, 2009, 10:00

NEW research which demonstrates that cows and badgers mix together while out in the fields much more than previously thought has rendered Government measures to tackle bovine TB “futile", a farming expert has said.

Campaigners have renewed calls for a targeted cull of badgers, which are widely held responsible for the spread of the infection, after a study by the Scottish Agricultural College (SAC) and the University of York revealed the two animals frequently have contact in fields.

It means that advice from Department for Environment, Food and Rural Affairs (Defra) to secure indoor areas where cattle are kept will not help to protect them from the disease.

Researchers believe a more effective method would be to target “high-risk” animals which are more prone to spread infection.

Anthony Gibson, a farming columnist for the Western Morning News, said: “This work shows just how futile it is to try to prevent contact between badgers and cattle in buildings, which is the mantra that Defra preaches to farmers. If cows are frequently having contact with badgers out in the fields, then there’s nothing you can do about it.”

He said some farmers’ efforts to keep badgers out of fields had proved expensive and pointless as they dug their way under fencing. The only solution was to cull infected badgers, he said.

But Defra stressed yesterday that its advice to farmers about bovine TB did not just centre on preventing contact between cattle and badgers in buildings.

A spokesman said the Government website included advice to farmers about the risks they should be aware of at pasture. He added: “It has long been known that there is contact between cattle and badgers at pasture and that it was likely this was frequent.

“However, it has not been easy to record how often this contact occurred (previous studies have been based on observation). We welcome all additions to our evidence base that could inform our understanding of this complex disease.”

Bovine TB cost the taxpayer £37 million last year alone, paid out to farmers in compensation for culled cattle.

Previous studies of cattle and badger contact have been carried out through human observation. But, in the latest case, researchers attached electronic monitoring equipment to both cattle and badgers. The devices record close proximity and the number of times the creatures met.

The findings of Dr Mike Hutchings of the SAC’s Animal Health Research Group and Dr Piran White of the University of York’s environment department are today published in research journal PLoS ONE.

It documents how researchers found that some badgers come into contact with certain cows more regularly than they meet badgers from other setts.

Dr Hutchings said: “The belief that, out in the fields, badgers and cattle avoided each other means we have been neglecting a potentially significant area of disease transmission between the species.”

Data also revealed some cattle are more curious than others, making them both more likely to investigate badgers, and then to mingle with other cattle ; a potentially fatal combination in the spread of infection.

Dr White said the new information could help improve measures to fight the disease. “Policy is currently against culling so we need ways to reduce disease transmission. This study presents one potential avenue to achieve this, through targeting specific, high-risk animals,” he added.

Jilly Greed, vice-chairman of the National Beef Association in the South West, is under restrictions for TB at her family farm in Thorverton, Mid Devon, meaning she cannot sell live cattle.

Signs of TB were found despite the farm following best practice, as laid out by Defra. “It seems all of our good work is a complete waste of time whenever our cows go out to pasture,” she said.

“We have even gone to the extremes of erecting electric fencing, and it’s massively frustrating to realise you just can’t prevent contact between badgers and cows.”

She said it had long been known that dominant cows, bulls and tame family pets were more likely to contract the disease, fitting with the scientists’ view that curious creatures had more contact.

Environment Secretary Hilary Benn yesterday defended his decision not to order a badger cull, saying he understood the frustration in the farming community.

He told the WMN: “I went with the science. We have tried culling ; that’s what the Krebs trial did. The evidence was clear ; if you cull reactively, you make it worse.

“If you go for a pro-active cull, you can benefit in the area where you are culling but create problems on the outside.

“I recognise that it was not a popular decision and that’s why I put a considerable additional amount of money into vaccine research.”

Six areas are expected to be selected for trials of a badger vaccine.

“I am very keen that we work with the farming industry and others to see what impact it has. TB is a terrible disease. I am determined to do everything we can to deal with it.”

:| Defra says it is okay to cull sick badgers ; NBA . . News. . 11th. August 2008.

The NBA TB committee has issued recommendations to the beef industry regarding the threat of bovine TB from badger populations. It said this was prompted by Defra Secretary Hilary Benn’s failure to ‘meet his legal obligation under UK and EU law to have an effective policy to ‘eradicate’ the disease.’

It recommends that farmers take note of Defra’s ‘Husbandry best practice advice’ on TB control, noting that 16 out of 21 of these guidelines refer to badgers with bTB.

The committee also referred to the words of Mr Benn in the Parliamentary debate that followed his announcement on a badger cull on July 7th.

Mr Benn said: “We know that badgers are infected and are a source of infection; no one argues about that.”

Later, he said that “section 6 of the Protection of Badgers Act 1992 allows someone to put down a badger if it is seriously injured or in such a condition that to do so would be an act of mercy. That is what the law currently says.”

Based on this, the TB committee states: “If a diseased badger is seen, Defra advice is for it to be humanely destroyed, and only the occupier of the land is permitted to dispose of the carcase which has to be done ’sensibly’.”

Police news release 29/04/2009

Badger Shot And Killed ; Nr. St Ives
On 23rd September 2008 Police received a report, via the Cornwall Badger Rescue and Brock Badger Group, of a dead Badger found on land in the Towednack area of St Ives. It was suspected that the Badger had been shot.

Sergeant Simon Dobson (a Police Wildlife Officer) attended and the Badger was taken for post mortem examination. It has since been confirmed that the Badger had been shot and a bullet has been recovered for evidential examination. It seems that the Badger was killed sometime between 8pm on 22nd September and 8.30am on 23rd September.

Under the Protection of Badgers Act 1992 it is a criminal offence for anyone to wilfully kill a Badger. This crime can carry a 6 month prison sentence. A formal investigation has now been commenced.

Sergeant Dobson is appealing for any information about this crime and about any shooting activity in the area. Any information can be given, confidentially, to Police on 08452 777444 or via the Crimestoppers line 0800 555111. Quoting Crime reference AI/08/864.

A 56-year-old St Ives man was today, Tuesday, 28 April 2009, arrested on suspicion of wilfully killing a badger contrary to Section 1 of the Protection of Badgers Act 1992.

After being questioned at Camborne Police Station, the man was released on Police bail to return on 12 June 2009. . . Police ref: MCA/09/1565

Update 1715 141008
The Cornwall Badger Rescue Group has since been approached by two businessmen from St Ives who have agreed to offer a £500 reward for information leading to the judicial disposal of this incident. Those making the offer do not wish to be identified.

Sgt Simon Dobson is investigating this offence. He said, “This may be the incentive that will spur anyone holding back information to come forward. I’d still urge anyone with information to speak to Crimestoppers on 0800 555 111″

I wonder if they even bothered to test the badger for bTB?

Road kill badgers are still not being automatically tested.

:| The British Veterinary Association (BVA) backs Welsh badger cull.

New Zealand who have an outstanding record for TB eradication say it will take about 20 years to eradicate TB from badger populations through vaccinations because it will involve annual vaccination of badger populations for some 4 - 5 badger generations. In view of this it is of little consolation that DEFRA is currently putting priority into badger vaccinations.

See: Bovine TB New Zealand
David, Devon

:| With a bacterium like Mycobacterium bovis, only an idiot would continue testing and culling cattle without culling the badgers also, the main reservoir species. . . Particularly considering their life-style.

Badger vaccination is a completely disingenuous diversionary tactic. . . Even cattle vaccination may yet prove to be completely futile when you realise the following statement was made by government in 2005.

“Schoolchildren will no longer be immunised against tuberculosis after public health experts decided the vaccination programme has little impact on control of the disease, the government said today.” . The cattle and badger vaccines being experimented with are based on the same BCG vaccine.

Dear Editor,

:| IT WILL come as no surprise to most vets and farmers involved with bovine tuberculosis that most cattle more recently sentenced to death by the now totally discredited Gamma Interferon blood testing regime were not only clinically healthy, but showed no sign of disease whatsoever at post-mortem.

The key to the efficacy of this test is its sensitivity and specificity. It was to be used alongside the skin test, certainly not instead of it. The skin test is now universally accepted as only really specific test for use in cattle and deer and other livestock.

There are very many different Mycobacterium in the environment with different strains of each, and clearly the Gamma Interferum blood test is unable to distinguish between them all, whether they be harmful to the host animal or not.

This blanket killing procedure is a disgrace to both Defra, the government body responsible, and the veterinary profession, particularly when no attempt is being made to cull and remove the major source of infection from the reservoir species — the badger.
