UK reminds pig producers to be cautious over swine dysentery
With the high risk of dysentery and cases being detected in Yorkshire, the British Pig Executive (BPEX) is reminding pig producers to be extra vigilant for symptoms of swine dysentery and step up defences.
"The disease can spread rapidly both within and between units, particularly in the current cold, wet conditions," warns BPEX's interim veterinary programme manager, Helen Clarke.
"With such an economically damaging infection, it is imperative any suspected symptoms are acted upon as soon as possible. Swine dysentery can vary in severity, ranging from mild diarrhoea to severe loss of growth, high mortality and bloody, mucoid diarrhoea. It is important to remain vigilant against any changes in faecal consistency or condition of pigs as severity of infection can develop," Clarke said.
She recommends that all producers tighten up on biosecurity measures.
Swine dysentery can live in manure and slurry for up to 60 days in cold weather, so producers must make sure their herds are well defended by reviewing (a) the cleaning and disinfection of vehicles, equipment and people; (b) internal and external biosecurity programmes specific to the farm and situation; (c) herd security - know the status of pigs and vehicles coming on to the unit; (d) vermin control - rats, birds, mice and insects; and (e) medication options - discuss with the unit vet where necessary.
