- A special breed of hybrid super pigs from Canada have started to travel south into the northern United States.
- The pigs pose a threat to native wildlife and may prove tough to eradicate.
- The spread of the pigs has only increased in recent years.
Originally crossbred to help farmed pigs grow larger and tolerate the cold temperatures of Canada, a drop in the market about two decades ago led some farmers to let their hybrid pigs run free. Now they’re running very free, according to Field and Stream. The super pigs are coming south, likely heading to Montana, North Dakota, Minnesota, and Michigan.
The problem? The super pigs are proving hard to eradicate.
