April 1st - new cattle meaures.

Following Consultations - [link] informing the cattle industry what it proposed to do, Defra introduced the first of its new proposals intended to kill more cattle, on All Fools Day 2017. We expect others will follow shortly.
 As expected, more extreme cattle measures pile on to extra restrictions on licensed movements into already restricted herds. Inconclusive reactors in particular, come in for special attention. And the use of gamma Ifn, a blood test which offers broad spectrum sensitivity to many bacteria other than m.bovis, is to be more widespread in the High Risk Area, and in cull areas after their first two years.

 Meanwhile incidence of zTuberculosis in the Edge area and the apparently Low risk area, increases.

 Details can be found on the Defra operated Tb hub - [link]
 
 Other than a few throw away mentions of 'bio-security' aimed at preventing cattle contact with infected badgers, we see no mention of any meaningful action on curbing the spread of zoonotic tuberculosis through this maintenance reservoir of disease whatsoever. This mind set of rubbish testing and a reservoir of disease in cattle, filters right down from the top end of Defra. And like their predecessors four decades, ago they are determined to stamp it out. But inevitably, as those predecessors found, - [link] unless the disease is eradicated in free ranging, over populated, super protected wildlife, an even bigger heap of dead cattle will make no difference to disease incidence at all.

But trust in and co operation with the Ministry responsible, already low, will disappear completely.

 This current Defra mindset is also contradicted by scientists working for Defra. Following a conference in 2014, reported by author Richard Gard in Vet. Practice - [link] the following observations were made by Dr. Noel Smith, whose painstaking work compiling a zTB genotype database was discussed:

Today, the various genotypes have a specific home-range. Some 95% of bTB breakdowns are in the home-range or within 50km of it and 97% of genotypes have a home-range. Dr Smith indicated that the spoligotype identified from a bovine slaughtered for bTB indicates whether the animal has been transferred out of the M. bovis home-range.

Dr Smith commented that:

“The observed geographical clustering of M. bovis genotypes is incompatible with a cattle-only transmission model for bTB in GB, or cattle-movement patterns. The geographical localisation of bTB home-range suggests a local, relatively static environmental (wildlife) reservoir of the bacterium”.

Perhaps Defra should talk to its own staff, or those of its more reliable agencies, more often.
