Manitoba’s chief veterinary officer (CVO) has confirmed the province’s fifth on-farm case of porcine epidemic diarrhea (PED) virus in a nursery finisher barn in southeast Manitoba. The presence of PED was reported by the herd veterinarian and confirmed by the province’s veterinary lab.
This farm is located outside the five-km buffer zone of two other farms where PED was confirmed last week. At this time, there is no known link between this case and previously diagnosed cases of PED. The CVO has begun identifying and contacting other premises that have been in direct or indirect contact with this farm to investigate how the virus may have arrived on the premises.
Investigations into the third and fourth on-farm cases continue and include testing for PED virus on nearby farms and other contacts. No additional cases have been found as a result of the investigations into the third and fourth on-farm cases. The CVO will attempt to determine the source of the infection to each farm site, though it is often difficult to definitively isolate the cause.
In all PED investigations led by the CVO between February 2014 and today, 1,090 samples from 182 farms have been tested for the virus.
