'Super Pigs' from Canada Threaten U.S. Invasion

These larger, cold-hardy pigs could exacerbate the existing problems caused by wild pigs, one of North America's most damaging invasive species.

Wild pigs, also known as 'super pigs', from Canada are threatening to invade the U.S. These pigs were originally crossbred by humans to be larger and more cold-hardy than their feral cousins to the south, with adults reaching weights exceeding 500 pounds.
Wild pigs are one of the most damaging invasive species in North America, causing millions of dollars in crop damage yearly and harboring numerous pathogens that threaten humans, pets, and meat production systems.
The wild pig population in the United States has nearly tripled and expanded from 18 to 35 states since the 1980s. More recently, they have spread rapidly across Canada.
Wild pigs are extreme generalist foragers, surviving on many different foods. They compete for resources with other wildlife and do severe damage through predation, killing and eating a variety of animals.
Efforts to control wild pigs are underway in the U.S., but the potential invasion of Canadian super pigs may complicate these efforts.
