A second sow operation in Manitoba’s livestock-intensive southeast is confirmed to be the province’s fourth farm with porcine epidemic diarrhea.
The provincial chief veterinary officer confirmed the latest case on Wednesday last week, following a confirmation at another sow barn in the same region on Sept. 19.
Most of Canada’s 69 farms confirmed with PED (not counting one southeastern Manitoba finisher operation that was confirmed with the virus earlier this year, then confirmed to be re-infected in July) are in southern Ontario, but that province hasn’t had a new case since July.
Surveillance and disease investigations into PED over the last nine months have turned up “several key components of biosecurity that need attention on many swine farms” in the province, Manitoba Pork said in a separate announcement Monday.
“In particular, biosecurity practices for service providers — such as feed and semen deliverers, meter readers and rendering collectors – are substandard,” the agency said.
For example, service providers are visiting multiple farms between car washes and not planning their visits to move from high- to low-health herds.
“We have to remember that many service people are not familiar with our industry,” Manitoba Pork said. “You have to be asking your service provider which pig facilities they have previously visited, when they were there, and when they last washed their vehicle. They could potentially be coming from an assembly yard, abattoir or other higher-risk site without washing.”
Furthermore, Manitoba Pork said, service providers such as feed delivery staff, who “have no need to enter the barns are entering the barns. When service providers do not need to enter a barn, every step should be taken to avoid it.”
Also, when service people are on-site, they’re not wearing disposable boot covers, thus carrying “whatever is on the site back into their vehicles and likely to the next farm, even if they are washing their vehicle between visits,” Manitoba Pork said.
Some deliveries or pickups, such as semen, medications, deadstock and regular garbage, shouldn’t require service people to drive down a hog operation’s driveway, Manitoba Pork added. “These contacts should occur either at the end of the driveway or well away from the site.” — AGCanada.com Network
