I remember reading that Division of Wildlife (DOW) released that accidentally/incompetently near Fort Collins, CO.

Colorado Parks and Wildlife found a parasite that can lead to hydatid disease in the scat of a wolf pack in Moffat County. Opponents of reintroduction call it a "major public threat" while supporters call it "not news."
The supporters are probably vegans. The parasite can infect elk and deer and coyote.

"The disease is the result of an infection caused by tapeworms of the family Taenidae. Of importance, is that the dormancy of this can be up to 50 years. It was previously most common in South & Central America, Middle East, China, and Western North America.
It has now arrived in the Northeast.
This is of equal importance to trappers and hunters alike in Maine and the rest of the Northeast. Although, some of us in the trapping community have been aware of the disease for a number of years and I was planning to write an article on it eventually, I have moved up its importance. This is based on the fact that IF&W has done research on it and just made the fact that is here public. Some of us assumed it would get here in the near future, but was not aware it had already actually arrived. IF&W presented it publically during Lee Kantar’s recent February presentation of his annual report on moose and deer to the legislature’s IFW Committee. I think trappers along with hunters should have been made aware of it immediately upon its discovery in Maine, considering our possible expose to it."
