I'd be more concerned w/the insecticides or fertilizers in ANY grass/lawn/field that I didn't control (or know of the care) personally. A lot of chemicals can be absorbed thru the skin, and the snake slithering on his belly would get quite a time of exposure. I'm sure washing (MAYBE a mild soap? or at least a loooooooong rinse w/clean water) would be okay, but I would be very diligent to keep an eye on him.
Besides, they're native to Africa and like the warmth...I don't think the heat outside is going to hurt for the amount of time he'll be outside moving around.
Enjoy!
