Manitoba Pork is calling for stricter biosecurity after a second Porcine Epidemic Diarrhea virus outbreak this month.
Both outbreaks were in sow barns in the southeastern part of the province.
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 says.
“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.
