New, old , new, old.

We have remarked before, that with TB non control, the more things appear to change, the more they remain the same. And so it seems with the introduction last August of a new farmer and veterinary package - [link] from APHA (Animal and Plant Health Agency) which includes a map of TB breakdowns surrounding the one to whom it was posted.

Introduced for new TB breakdowns in the High Risk and Edge area last August, this is far more detailed than the badger Activist's Road map - [link] produced a couple of years ago after a change in the Data Protection statutes. We showed it in the posting below, with an 'X' marks the spot on Mr. Durose's farm.
Today, Farmers Guardian - [link] have more on this story.

The building blocks of outbreaks in the area surrounding his farm over the last four years, were as shocking as they were indefensible. Mr. Durose's herd had been clear of TB and on annual testing for decades.

In the leaflet, the new mapping system is described thus:
d). TB breakdown map - included on the final page is a map showing the geographical location of the holding and geographical data that is held by RPA (i.e. an outline of owned and/or rented land that is registered against that CPH with RPA). [snip - explains helpfully, that short term grazing may not be included.]

This map also indicates the location of other recent breakdowns within the area surrounding the holding of interest, along with details of any genotype(s) isolated from them (if available). This information can give an indication of the incidence, weight of disease and identified M.bovis genotype(s) present within the localised area around the breakdown under consideration. This can help in considering the risk of locally acquired versus imported disease.
But how 'new' is this idea?

 In 1972 a local vet at the Truro office began combining computer datasets with his curiosity into the origins of local TB outbreaks. All badger post mortems were logged, together with those from cattle as they became available. Spoligotypes and locations were painstakingly listed to show the depressingly familiar outwards spread we see today.

These maps are now part of a collection in the National Archive - [link]  who describe them thus:

The datasets record the incidence of tuberculosis among cattle in Great Britain from 1977 to 2002; and record of incidence of tuberculosis among badgers, as potential carriers of disease, from 1972 to 1998. The system links data showing incidence of TB to computer-generated maps; the original name of the database was 'TB Maps & Stats'.
On seeing Apha's 'new idea' Dr. Roger Sainsbury, whose painstaking work over more than two decades was for Ministerial internal consumption only, remarked wryly:
I wonder how many farmers will be shocked to see how much ‘Big Brother’ knows about their activities?
and he also noted that:
We always used to ask questions to get this information. It occurs to me that they (Defra / APHA) must be very sure that their info is 100 per cent.

As we now live in a society thriving on litigation, we hope it is too.
