Farmscape for March 1, 2023

The Canada West Swine Health Intelligence Network is advising pork producers and transporters to consider all high traffic areas as contaminated with Porcine Epidemic Diarrhea.
The outbreak of Porcine Epidemic Diarrhea that has been ongoing since October 2021 in Manitoba is among the topics covered as part of the Canada West Swine Health Intelligence Network's just released swine disease surveillance report for the fourth quarter of 2022.
CWSHIN Manager Dr. Jette Christensen says the cleanup is progressing but, in some locations, full cleanup may not be feasible until spring.

Clip-Dr. Jette Christensen-Canada West Swine Health Intelligence Network:
Quarter 4 went very well.
The last case in quarter 4 was in late October.
There were no new cases in November and December and more and more farms got presumptive negative status, however in January and February there have been some traffic sites contaminated with PED.
That has heighted the awareness and it's heightened the demand for good biosecurity for all vehicles that transport pigs.
Producers, barn managers, transporters and veterinarians should note that the number of positive surveillance covers all high-risk premises so it could be assembly yards, large and small processing plants, holding facilities.
This winter weather, it is extremely difficult to clean and control this PED on these high traffic sites, so assume they are contaminated.
Keep high biosecurity when you have any vehicles coming from these high traffic places.
You should also be on the lookout for clinical signs, diarrhea with PED.

Dr. Christensen says, as of February 21st, there were 43 active premises that have not yet reached transitional status, including one that had its presumptive negative status revoked after clinical signs resurfaced and three that were declared infected because they received recovered pigs.
