First, Canada sends their geese, and now these. Imbedded video includes an infographic depicting the spread. Apparently, they also build “pigloos.”

The cross between a European wild boar and a domestic pig is migrating south, to the US, as their numbers swell in Canada.

A cross-bred “super pig” from Canada is poised to wreak havoc on the environment in the United States and must be dealt with aggressively and immediately, a wildlife expert told Fox News Digital.

“These pigs are easily the worst invasive large mammal on the planet,” said Dr. Ryan Brook, an assistant professor in the department of animal and poultry science at the University of Saskatchewan in Canada.

These “super pigs” are actually a cross between a European wild boar and a domestic pig, Brook said.

The pigs “cause crop damage, destroy natural environments, get into cities, destroy water quality and can spread disease to humans, livestock, pets, and native wildlife,” he also noted.

The pigs are coming into the U.S. from Canada as their numbers swell there, causing populations to migrate south. Left unchecked, these “super pigs” could negatively impact just about everyone, Brook emphasized.

“The only people who should be worried about this is anyone that lives in North America and eats meat, or eats vegetables, or eats any foods based on grain crops or spends time outside for any reason,” he said.

The “super pigs” began with a unique set of circumstances, said Brook.

“Wild boar farmers were told to cross the wild boar with domestic pigs to make a bigger and longer animal,” Brook said.

He said a domestic pig has an extra set of ribs and has larger, more frequent litter.

“This was great for wild boar farmers, but [it] was a huge problem when [these animals] got into the wild,” he said.

The animals’ size, along with their intelligence, has made the “super pigs” capable of survival in harsh conditions and therefore hard to eradicate, said Brook. He noted they’ve even learned how to tunnel into snow caves to keep themselves warm.

“It is much warmer under than snow than on top of it,” said Brook.

Eradicating these wild pigs must be done as “quickly as possible,” he emphasized.

There must be “a rapid and highly aggressive response, just like dealing with cancer or forest fires — that is really the only option.”

He added, “Once [the pigs] are established, you will have them for another 500 years.”

Traditional hunting techniques are not effective in pig eradication, said Brook.

“Large traps and tracking Judas pigs (wild pigs with a GPS collar that will lead you to other pigs), ground removal teams, fencing, and education are all key,” he said.

Failure to quickly eradicate the pigs will result in devastation to the environment.

But how do they taste?
