The figures, welcomed by Deputy Minister for Agriculture Rebecca Evans, were collated by Defra and showed a 31 per cent decline in the number of cattle slaughtered in Wales as a result of bovine TB on the previous year.
In addition, for the February to May period this year, the figures suggested new incidents of the disease in 2014 were at their lowest level since 2008.
Ms Evans said: “Bovine TB continues to be one of the biggest problems facing the farming industry in Wales. It is a devastating disease and one which, as a Government, we are working hard to eradicate.
“While we know disease figures can fluctuate from month to month, these latest statistics continue to indicate a downward trend for bovine TB in Wales and this is very encouraging news.
“Our comprehensive TB eradication programme, which has now been in place for more than five years, is based on solid evidence, and includes annual testing of cattle, strict biosecurity measures and movement control.
“However, we know eradicating TB requires hard work, sustained effort over many years and a high level of co-operation between Government and the industry.
“We know there is much more to do to eradicate this disease from Wales, these statistics do show we are moving in the right direction and our hard work is starting to make a difference to the disease picture in Wales.”
Figures showed 826 new incidents of bovine TB in Wales between June 2013 and May 2014, compared with 1,009 between June 2012 and May 2013 – an 18 per cent decrease.
A total of 5,936 cattle were slaughtered in Wales as a result of TB between June 2013 and May 2014, compared to 8,595 cattle slaughtered between June 2012 and May 2013 – a 31 per cent decrease.
