A BAN on all movement of cattle, pigs and sheep has come into effect in Devon as part of a nationwide clampdown following a foot and mouth outbreak near Guildford in Surrey. Farmers in the county are unable to take their animals to market or for slaughter which is making things difficult, Okehampton and Hatherleigh NFU group secretary Simon Whattler said this week. Mr Whattler said the ban would be in place for two weeks but what happened after that would depend on whether there were more outbreaks. ?We certainly would not want to see again what happened in 2001,? he said. ?Thankfully it seems like an isolated incident and one which is traceable. If they can attack the source, and nail it, some of the worry can be eased away.? Animal health officers of Devon County Council Trading Standards are working in close liaison with Defra, tracking events in Surrey and standing ready to take any further action. It is emphasised that there are no cases in Devon, but vigilance and tight biosecurity are vital. Farmers are therefore advised to remain vigilant, step up their biosecurity and allow only essential vehicles onto their premises. Livestock movements will only be allowed under strict licence and information about those arrangements will be communicated as swiftly as possible. Leader of the county council Brian Greenslade said: ?People in Devon know the full impact that foot and mouth can have on communities. ?Our thoughts are very much with the affected communities in Surrey and the farming families. Our thoughts are also with the animal health officers and vets who are in the front line to contain this outbreak as swiftly as possible. ?Here in Devon it is important that we remain calm and do everything we must to ensure good biosecurity. ?I know our farmers will heed the ban on the movement of cattle, pigs and sheep, step up their biosecurity and remain vigilant.? Advice regarding the outbreak can be sought from Defra who have established a helpline on 08459 33 55 77.
