I wouldn't worry, Coral snakes are rear fanged and have very small mouths and are also fairly timid, I've seen them handled by accident without biting. Chances of being bitten are fairly rare and having a non-dry bite even less.

"Micrurus alleni. Coral snake. If the color pattern spells frog in spanish (RANA = rojo, amarillo, negro, amarillo), then beware. Coral snakes have a very potent neuro-toxin in their venom, but will generally bite only if provoked or tred upon."
