CWSHIN Q4 2021 report and disease news


View the CWSHIN Q4 2021 report as a PDF

The CWSHIN report for the fourth quarter of 2021 has been released.

With funding from provincial pork boards and governments, as well as the participation of registered veterinarians in the four western Canadian provinces, the Canada West Swine Health Intelligence Network (CWSHIN) serves the western Canadian hog industry to improve swine health, production and the economic prosperity of the sector..

Find below a summary of information from that report, relevant to Alberta pork producers.


  • Porcine epidemic diarrhea (PED) continues to spread in Manitoba.
  • Flooding in B.C. affected hog barns worse than what was reported in news media. Lameness, prolapses, back injuries, lack of feed, excessive feed, poor quality feed all contributed to welfare issues.
  • African Swine Fever (ASF) has been detected in mainland Italy. A different ASF serotype has been endemic to Sardinia (an Italian island) for many years, meaning these recent outbreaks are not connected.


Disease updates

  • A total of 67 premises in Manitoba have confirmed cases of PED – an increase of 60 cases since the CWSHIN Q3 2021 report was released. About half of the cases affect finisher barns, while the other half affect sow barns, farrow-to-finish operations, nurseries and nursery-finisher operations.
  • Alberta Pork is closely monitoring movements from Manitoba. No cases of PED have been found in Alberta since 2019.
  • Under CanSpotASF rule-out testing, across Canada, 86 per cent of eligible and 27 per cent of all submitted pathology cases tested negative. Sow mortality, torsions and erysipelas all conditions eligible for ASF rule-out testing.



  • Abattoir loading docks should be considered high-risk for disease contamination, especially PED. Exercise extra caution when vehicles return from these sites.
  • If you see scours in your herd, contact your vet for a full PED investigation.
  • ASF rule-out testing continues under the CanSpotASF surveillance program. Vets can request this testing through their provincial labs.
