Yup...& it's also used in mouthwash (human use), but snakes are not humans, & wounds are a different thing, IMO...there is every reason to minimize bacteria in a wound, and you still aren't normally bathing a snake in it...not many snakes have wounds covering their entire bodies, not live ones anyway.
Many things are used by humans for good purposes that are later found to have huge downsides, either to us or to the environment. For humans, it often takes 30+ years for the negative research to leak out while companies do their best to make money off an "iffy" product- for example, "partially-hydrogenated fats"...promoted in margarine as healthier than real butter, now known as "trans fats" & banned or avoided in many foods, yet still marketed in snack & fast foods because hey, they can get away with it!http://www.euro.who.int/en/media-cen...ing-trans-fats (this is just one example, the list is long)
So ( if it takes 30+ years to care about human safety?) how long do you think it will take before this issue is researched for safety with SNAKES?Not holding my breath.
