Lizards should be able to eat raw meat without food poisoning.

To elaborate a bit more I think -what- races can eat can help them be a little more unique

cows getting extra buffs from veggies for example might encourage more cow botanists and ranchers, which would be cute

lizards obviously skulking around medbay for organs (i see humans vaccuum them up on main all the time lol)

roaches eating food that would make them sick might instead not affect them?
