Western Canada's support for Swine Health and Disease Surveillance


CWSHIN connects members of the swine sector from across western Canada to share information on current swine health trends. We are a surveillance system imbedded in an intelligence network.

Using elements of science, management, communication and documentation, CWSHIN:

  1. Applies modern surveillance and epidemiologic methods to data collected from practitioners, laboratories, abattoirs, etc., and provide swine health intelligence to producers and swine veterinarians in western Canada.
  2. Monitors worldwide swine health trends, to allow for a better understanding of advances and potential threats.
  3. Strengthens the surveillance system and intelligence network through strong governance within the CWSHIN team and collaboration with swine health stakeholders.
  4. Communicates with producers, practitioners and governments to grow the network.

Early detection of emerging swine health issues, such as increased prevalence of common diseases or minimizing the impact of new diseases to the sector.
Improving control of diseases by integrating response information to regional health issues.
Providing western Canadian producers and veterinarians with current regional, national and international disease information.
Maintaining international market access by providing evidence of the absence of reportable disease.


CWSHIN Report on Swine health surveillance for Quarter 1 2019 –14 May 2019

Practical tips

Use “war-time biosecurity measures” for the next 6 weeks as we are into the high-risk period for PED.

Contact your swine practitioner if your see diarrhea.

Strict biosecurity both at the border and surrounding each farm is still paramount.


The high rate of respiratory lesions at abattoirs in SK/MB that we have seen in 2018 has dropped so SK/MB is now on par with East.

The total number of regional PED confirmed cases in the first quarter of 2019 was: 4 cases in AB and 2 cases in MB.

A desirable increase in submissions for diarrhea and PED awareness was seen in AB following the first cases of PED.

The high-risk period for PED in Manitoba extends from the beginning of April to mid-June so there is every reason to apply “war-time biosecurity measures” for the next 6 weeks.

Porcine Circovirus 3 (PCV3) has been detected by PRC by PDS. However, it is not known if PCV3 is an emerging new disease or a harmless virus.

Classical Swine Fever (CSF) is a challenge in backyard pigs in Brazil and in wild pigs in Japan.
