and Food (MAFF) imposed movement restrictions on livestock in and out of eight kilometres around the infected area. On 21 February, the European Commission announced a blanket ban on the export of any meat, milk products, or livestock from the UK. On 23 February, a case was confirmed in Heddon-on-the-Wall, Northumberland, from the same location as the pig in the first case; this farm was later confirmed as the source of the outbreak, with the owner, Bobby Waugh of Pallion, found guilty of having failed to inform the authorities of a notifiable disease and banned from keeping farm animals for 15 years. He was later found guilty of feeding his pigs "untreated waste". On 24 February, a case was announced in Highampton in Devon. Later in the week, cases were found in North Wales. By the beginning of March, the disease had spread to Cornwall, southern Scotland and the Lake District where it took a particularly strong hold. During investigation of the Great Heck rail crash, which took place on 28 February in North Yorkshire, investigators visiting the crash site had to go through a decontamination regimen, to prevent possible contamination of the crash site's soil with the virus. The MAFF adopted a policy of "contiguous cull" – all animals within of known cases would be slaughtered. This was immediately clarified as applying only to sheep, not cows or pigs. The policy of MAFF was that where affected carcasses from the cull could not be disposed on site, they would have to be taken to a rendering plant in Widnes; as such, the corpses of infected animals were taken through disease-free areas. Control measures By 16 March, the number of cases was at 240. Around the time, the Netherlands had a small outbreak, though the disease was contained by vaccination; the vaccinated animals would later be destroyed, in line with EU requirements on trading. David King was appointed to approach MAFF policy in a scientific manner, alongside Roy M. Anderson, an epidemiologist who had been modelling human diseases at Imperial College and was on the committee concerned with BSE. By the end of March the disease was at its height, with up to 50 new cases a day. In April, King announced that the disease was "totally under control".
