New Science in the Hunt for Wild Pigs
January 9, 2025
As wild pigs remain an ecological threat in Manitoba and across our country, finding the truth of where they are, how they move, and where they thrive can be quite a process. Luckily, Squeal on Pigs Manitoba, Assiniboine College and BDx ENVIRO Laboratories are on the case with a rapidly emerging, sensitive detection method.
Squeal on Pigs Manitoba is now analyzing environmental DNA (eDNA) to detect the presence of wild pigs across our province, using a process that involves the collection of a water sample in a watershed where a wild pig’s presence has been suspected.
“Very limited research has been done across North America on developing this type of test, and we are proud to say that this test was done completely by researchers and scientists working in Manitoba,” says Dr. Wayne Lees, Project Coordinator for Squeal on Pigs Manitoba. “Our hope is to deploy this test across Western Canada so that we can have a much better sense of where wild pigs are to remove them from the landscape.”
“The applied researchers at Assiniboine College lead the field work and lab testing, with support from Squeal on Pigs Manitoba in locating potential test sites,” adds Chris Budiwski, Chair of the Russ Edwards School of Agriculture & Environment at Assiniboine College. “Modelled after research done by the United States Department of Agriculture, we are adapting this innovative testing process to Manitoba’s cold climate and forested areas.”
This test will be essential to tracking herd populations and better understanding their potential threat as vectors for highly pathogenic viruses like swine influenza, pathogenic E. coli, and African Swine Fever (ASF), all of which could pose a significant threat to wildlife, the environment, and Manitoba’s economy. eDNA testing also allows for screening in more remote areas where it’s difficult to rely on human sightings. Assiniboine College researchers have already collected 280 water samples and submitted them to BDx ENVIRO for analysis.
Squeal on Pigs Manitoba started as a collaboration between Manitoba Pork and the federal and provincial governments in May 2022. Squeal on Pigs staff deployed an average of 80 trail cameras and 25 traps per month on private land in the months that followed. In 2023, that led to 157 wild pig sightings and 127 wild pigs removed from the landscape.
Squeal on Pigs Manitoba will continue to work with provincial stakeholders and landowners on this problem, breaking new ground in research and data analysis.
