Canadian herds take steps to PED-negative status

More than 40% of hog farms in Manitoba, Canada that were infected with porcine epidemic diarrhea are no longer testing positive for the disease, officials say.

Following an initial outbreak in April 2017, 78 hog farms in the province were infected with the disease, including 25 sow herds, 16 nurseries and 37 finisher operations, reports The Pig Site.

But after an extensive surveillance and biosecurity program, including limited animal movements, many of those operations had driven out the disease from their herds.

Dr. Glen Duizer, with the Office of Manitoba’s Chief Veterinary Officer, said 32 operations have moved to “transitional status,” which means they can ensure the pigs coming off their farms are negative for PED.

“Additionally six of the 32 promises have moved on to become presumptive negative, [which means] that not only are the pigs negative, but all contact surfaces, offices, facilities around the premises are considered negative for PED,” he said.

Duizer said it is possible that live PED virus could still be in the farms’ manure and manure handling equipment, but repeated testing shows the businesses are at a very low risk for the disease.

As direct animal movement was responsible for 30 of the 78 cases, Duizer said it is important that producers still take care and ensure the highest biosecurity measures possible.

Movements can take place, but if they can be minimized or delayed in a way which will limit the spread of disease it will help, he added.
