Certainly if we are looking to the farmer to ‘do-it-himself’ rather than utilise Ministry manpower / resources CO is no doubt a more usable gas.<BR/><BR/>The point is that the already proved-to-be-useless theoretical approach should have been replaced with practical tests with variables such as 1 – 2 petrol engines, 1 – 2 hours, vented / non-vented chambers, controlled exit (none, one, two) and gas flow measurement / monitoring with visible coloured gases – etc etc. Not beyond the wit of mankind – even for Defra folk! <BR/><BR/>However – if either Ministry men and / or the Army were to be deployed then I would not hesitate to use proven HCN technology (again), I have previously proposed that the size and nature of the bTB debacle is such that it warrants the skills of the army (a la FMD)<BR/><BR/>One wonders incidentally how MAFF / Porton Down assessed the efficacy of HCN when it was decided that it may not be / was not humane bearing in mind that Hydrogen Cyanide is also used for capital punishment in gas chambers in six states of the USA!<BR/><BR/>I have had direct experience of dealing with MAFF when I was worked for a molecular modelling pharmaceutical PLC on, amongst other things, its BSE (and CJD & Scrapie) project.. We discovered and developed a compound to accurately identify BSE (CJD / Scrapie) (post mortem). MAFF was just as useless then as DEFRA is today – but once again Ireland assisted with the real world testing whilst MAFF just shredded 17 vital files (of documentary evidence) prior to the official inquiry.<BR/><BR/>PETER BRADY<BR/>SETTAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6885842.post-12202018335950230372008-07-29T17:22:00.000+01:002008-07-29T17:22:00.000+01:00Peter you need to compare 'like with like'Thornbur...Peter you need to compare 'like with like'<BR/><BR/>Thornbury setts were gassed with hydrocyanic acid not CO<BR/><BR/>Are you proposing using cyanide?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6885842.post-64459942232476303642008-07-29T16:32:00.000+01:002008-07-29T16:32:00.000+01:00What absolute balderdash!

I couldn’t stop laughing! <BR/><BR/>I had to go back to the documents published on DEFRA’s website <BR/><BR/>http://www.defra.gov.uk/animalh/tb/abouttb/badgers.htm#rep<BR/><BR/>People – including Badger Trust reps and DEFRA ministers actually think this stuff is scientifically relevant.<BR/><BR/>It really is difficult to believe the Nation has very recently paid for the following Defra-sponsored piece of Harry Potter nonsense. I detail below extract of DEFRA report:-<BR/><BR/>© Crown copyright<BR/><BR/>Further development and validation of a CFD model of gas diffusion within a soil tunnel A report to Defra 25 June 2008<BR/><BR/>9. CFD modelling predictions of CO concentrations in an approximately 1/5th scale model of a simple, natural tunnel system surrounded by real soil showed inconsistencies with the experimental data, with the model predicting higher concentrations in the surrounding soil than were observed experimentally. There were also discrepancies between results obtained from the different experimental runs under nominally the same conditions.<BR/>10. A number of possible issues contributing to these discrepancies were highlighted at an expert working group meeting, and a modified experiment was carried out using more soil, that was air-dried and sieved through a 2mm sieve.<BR/>11. Despite this the modelling still showed poor agreement, in particular predicting a continuous increase of CO concentration after 60 minutes, whereas experimentally concentrations generally levelled off after 40 minutes.<BR/>12. This led to the conclusion that based on the comparison of the experimental results with the CFD, the current understanding of the physical processes for the dispersion of CO in soil is insufficient for modelling the dispersion of the gas. This may be due to the deviation of real soil from the assumption in the CFD software that it is a uniform substrate.<BR/>13. Validation of the model in natural tunnel systems (phase 2) was thus abandoned. However, four scenarios were identified as potential ways of collecting data from physical systems for validation of predictions made by any future model.<BR/><BR/><BR/>Really – what has this got to do with ‘reality’ – someone creates a fantasy world – says something can’t be ‘modelled’ and those that wish to - conclude that – in this instance – the in-sett gassing of badgers doesn’t work and won’t work! <BR/><BR/>But we know it does – don’t we?<BR/><BR/><BR/>THE THORNBURY BADGER CLEARANCE 1975-1981<BR/><BR/>….the Thornbury badger clearance has been quoted as irrefutable evidence for-badger to-cattle transmission. 1975-1981 badgers were totally cleared from 104 sq kilometres centred on Thornbury, Avon. Setts were gassed with hydrocyanic acid and recolonisation prevented by further gassing until 1981, after which it was allowed to proceed. The 104 herds in the area were thereafter free of TB until 1992. The decline of the disease, in step with badger clearance was studied by Clifton-Hadley et al from detailed records of reactor numbers, false positives and false negatives. The authors concluded that "eradication of tuberculous badgers resolves the cattle problem for at least 10 years."<BR/><BR/>As they say - watch my lips!<BR/><BR/>GASSED BADGERS DON’T PERUTUBATE <BR/><BR/>GET REAL!<BR/><BR/>PETER BRADY<BR/>SETTAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6885842.post-24846657744243270482008-07-29T10:47:00.000+01:002008-07-29T10:47:00.000+01:00QUESTION:Given a hole in the ground how long does ...QUESTION:<BR/>Given a hole in the ground how long does take two men with a detuned petrol engine to kill the diseased badgers therein?<BR/>ANSWER:<BR/>Not as long as it took in the 1980’s and the Thornbury model worked very well!<BR/><BR/><BR/>Defra very recently published all of this stuff on its website – much of it dated back to 2005<BR/><BR/>The fact that an expensive mathematician hasn’t been able to model the efficiency of in-sett gassing of is of no significance. – nor are the comments regarding shooting and snaring.

The pyramid-shaped parish is bounded to the east and to the west by Castlechurch and Bradley respectively, and by the parish of Dunston to the south. Bradley and Dunston hold the majority of herds. Mr Madders reported that his herd is 'self- contained' and that 'the only way in is through wildlife'.<BR/>Using the Freedom of Information Act, the Badger Trust secured details of herds and bovine TB outbreaks in all four parishes, from<BR/>1995 to 2006. The total number of herds registered on VetNet in all four parishes declined from 67 to 49 over that time. The bulk of the decline occurred in the wake of foot and mouth disease (FMD). The Stafford disease control centre dealt with 72 FMD incidents during the outbreak and for some farmers it prompted retirement from the industry.<BR/>The data obtained by the Badger Trust reveal that TB was virtually unknown in the four parishes between 1995 and 2002. Only a single herd, in the parish of Bradley, went under TB restriction, and then only from 1998 to 1999. Thereafter, there was no evidence of bovine TB until 2003.<BR/>In 2003, in the wake of FMD, three herds went under restriction, one in each of the three parishes surrounding Coppenhall, followed by a fourth in 2004 in Bradley. The number under restriction dropped to three again in 2005 and the outbreak on Mr Madders' farm took the number back up to four in 2006.<BR/>This sudden upsurge in 2003 mirrors that which occurred all over the country in the wake of FMD. This followed Defra's stupendously foolish decision to allow the movement of untested livestock for restocking, which the NFU claimed as a "victory". The buying-in of TB infected cattle led to a huge rise in the distribution of TB infection right across Britain and an explosion of new cases. For thousands of farmers, it proved to be a pyrrhic victory.<BR/>"The unavoidable fact is that Mr Madders' TB outbreak would never have occurred were it not for the movement of untested, TB-infected cattle to South Staffordshire," commented Trevor Lawson. "The<BR/>disease was virtually unknown in the four parishes for at least eight years. There is no evidence explaining the final route of the disease to Mr Madders' farm. Officers of Animal Health cannot claim, with any shred of certainty, to know the cause.<BR/>"If free-roaming badgers were the TB vector for Mr Madders' farm, it does not explain why the three other herds in his parish have escaped the disease. Indeed, 92 per cent of the herds in the four parishes are currently TB-free. Infected badgers, surely, would cause a "clumping" of infection and cannot explain this scattered distribution. Officers of Animal Health cannot possibly claim that badgers are the index source of this infection. Clearly, cattle are the index source of this disease. Animal Health should publicly apologise to Mr Madders for misleading him in this way."<BR/>ENDS<BR/>For further comment, please contact Trevor Lawson on 07976 262388.<BR/>1.

They did not cause an ongoing problem, and some, although you may not have realised this, were not carrying the spoligotype of TB unique to their herd of origin. In some of the Cumbrian cases, TB in imported cattle, was entirely home grown. <BR/><BR/>So cry if you like - for the badgers, lying dying all over our neighbour's fields. For the waste of his dead heavily in-calf cattle, and for our own new TB reactor, soon to leave us an orphan calf and the chaos of 60 day testing.
