is the minimum age to handle/touch a snake. I have a four year old girl who is begging to touch my boa. I've read that a child's immune system is only fully developed when they are 5 years, and even though I am "Monk like" in my cleanliness regimine of my only two snakes, I know it's possible they could carry salmonella (like all reptiles.) Is washing hands before and after handling enough at this age, or should I just play it ultra safe and wait another year?
