Dr. Glen Duizer from the Chief Veterinarian’s office of Manitoba Agriculture joined us Wednesday to discuss the recent spread of PEDv in Manitoba. Thank you Dr. Duizer for sharing your knowledge. Thank you as well to everyone that could tune in to hear them speak.
His presentation was filled with excellent information, but we’ve put together a few main points from his talk regarding the risk factors present when PEDv strikes a premise near your barn.
In the event of a PEDv outbreak in Alberta, a high-risk buffer zone will cover the 5 km radius surrounding any PEDv-positive premises. You may find that your barn lies within a high-risk buffer zone. Alberta Pork will notify you if this is the case. Should this happen, there are a number of risk factors you should consider.
It is important to note that although the following practices are for buffer areas and infected zones, they can be a good practice for day by day Biosecurity.
Area spread of PEDv may occur due to natural or unknown causes. Wind is an example of an agent of area spread. Wind may blow contaminated dust from infected premises to within the CAZ (Controlled Access Zone) or RAZ (Restricted Access Zone) on your own premises. Stricter Biosecurity precautions can mitigate the possibility of area spread, such as keeping doors closed, and regular changing of boots between CAZ and RAZ.
Sharing staff and equipment between barns and premises is a common practice. When a barn is within a high-risk buffer zone, this can pose a risk for further spread of PEDv into the barn. Extra precautions such as renting a trailer for an extra shower site may be advisable if your premises are within a high-risk buffer zone.
Movements between PEDv-negative barns within a buffer zone and barns outside of the buffer zone may risk the spread of disease because transport trucks may travel through infected areas to reach the destination.
There are many situations which require frequent transportation of pigs between barns. Each movement poses only a small risk of infection spread. However, the frequency of movement multiplies the potential risk of PEDv spread. This has the potential to rapidly spread PEDv downstream. Reducing and restricting movements wherever possible will mitigate this risk.
Alberta continues to test negative
Alberta Pork, Growing Forward, and the Alberta Government are working together to monitor the spread of PEDv. We have found no PEDv-positives to date. Producers will be notified if PEDv should appear in Alberta.
As always, Alberta Pork is here to help producers. We will continue to keep you informed on the best practices in fighting against diseases like PEDv.
