I told a few people that Elephants can get FMD, (Foot and Mouth), and thay just laughed at me. Well this is what I've just found on the DEFRA web site

Which animals are susceptible to FMD?
Among farm stock, cattle, sheep, pigs, and goats are susceptible, as are llamas and alpacas. Some wild animals such as hedgehogs, coypu, and any wild cloven-footed animals such as deer and zoo animals including elephants can also contract it.
