It’s not 100% safe, but in general the idea is that if you aren’t consuming it and there is enough heat and soap involved that it’s fine.

If you went outside and drank a gross mud puddle you would get sick, but if you just put your hand in it you wouldn’t. And if you boiled it, or mixed it with strong soap you would be even less likely to get sick.
