The risk to the pig industry from exotic and emerging diseases is at its highest level since 2001, with African swine fever (ASF) spreading from Eastern Europe and porcine epidemic diarrhoea virus (PEDv) recently identified in Eastern Europe; PEDv is also present in Canada and continuing to spread with devastating speed through North America. In addition to these new threats, there is still a risk from Foot and Mouth Disease and Classical Swine Fever.
Outbreaks of notifiable disease do serious harm to the industry and can potentially lead to closure of export markets.
The Pig Health and Welfare Council Surveillance Subgroup Exotic and Emerging Diseases Roundtable in April 2014 developed a series of recommendations to strengthen the UK pig industry’s defences against the introduction of new and notifiable diseases and to improve preparedness to identify quickly, contain and eliminate new disease agents.

Ivermectin resistance confirmed in Oesophagostomum species worms in pigs
Resistance to ivermectin was confirmed in the roundworm Oesophagostomum dentatum obtained from a pig farm in England. An initial investigation into a suspected case of reduced ivermectin efficacy was undertaken by the veterinary practitioner involved together with the Animal and Plant Health Agency (APHA). The results from the initial on-farm study led to a controlled efficacy trial being undertaken at the Moredun Research Institute in collaboration with APHA and AHDB Pork using worms from the farm on which the initial investigation took place. This trial confirmed the finding of the first reported case of resistance to ivermectin in adult O. dentatum worms in the UK.
