Minnesota fighting PRRS long-term
Minnesota pork producers, veterinarians and University
of Minnesota researchers have recently formed a task force trying to rid swine
herds of porcine reproductive and respiratory syndrome
The task force (MNPETF) aims to eliminate PRRS
just like pseudorabies was eradicated in commercial
herds. It took 20 years to eradicate pseudorabies
it might just take as long to do the same with PRRS.
Costs for pork industry
The disease costs US pork industry at least $560 million through death
losses and production declines on a yearly basis. Through the task force's
efforts, the state's 5,000 pork producers can expect to see more on PRRS
management practices and how they can adapt those practices on their own pig
The task force's eradication efforts will be producer-led and voluntary, it
is claimed, since MNPETF members believe that producer-to-producer communication
and research information transfer to the farm-level will eventually lead to
successful PRRS eradication.
It is not surprising Minnesota is the first state to organise a task force
like this, since Minnesota pork producers, researchers and veterinarians have a
track record of cooperatively addressing industry issues.
North Carolina and Indiana are reviewing Minnesota's task force structure
for adoption, and the Canadian province of Ontario has an active PRRS group
already in place.
Methods currently used to remove PRRS virus from a farm include whole herd
depopulation-repopulation, test and removal, and herd closure. Farms that have
held PRRS at bay can find its animals infected even when practicing tight
