I also handled these all the time as a kid in northern Oregon, literally hundreds in a day because they would hang out in a series of lakes nearby. Is there a non-poisonous rough-skinned newt variant? I find it impossible to believe that as a young kid I wouldn’t have licked my fingers after years of doing this.
I'm not aware of other newt species in their range that look similar.
I do think the article plays up their toxicity some. There's only one reported human fatality I could find, from some dipshit who ate one on a dare. If you handle them gently and don't stuff your entire hand in your mouth immediately after, I suspect you're fine.
