Is Snow Ice Cream Safe To Eat?

Today there's a lot of snow in my neighborhood and I thought about making snow ice cream but my mom says it's not safe to eat. I think it should be safe, I've heard many people eat snow ice cream.
Basically, what I want to know is if it's actually dangerous to eat snow cream or if I'm going to be fine.
I've seen many little kids eating it and they are fine now.
Any answers will be appreciated, thanks.

I think it is safe to eat snow ice cream, I've been eating it since I was a kid and I never got sick.
It's just snow that fell from the sky so I can't imagine why it shouldn't be safe.
And as you said, there are even recipes online about how to prepare snow ice cream, if it wasn't safe I don't think anyone will take the time to write something about it.
So I say it's safe.
