The "elephant curator" at Oregon Zoo was warned about tuberculosis transmission issues related to his management of the animals, and he chose to ignore it, secure in his belief that he knew best. Oddly enough, three of the animals contracted TB. Two of them are dead, and it appears that the third - and oldest - now has one foot in an incinerator and another on a banana peel.
And what are the idiots doing? Why, they've been allowing an animal that they infected with TB to roam areas of the facility so that he can infect the few remaining elephants there. Brilliant. And taxpayers are still paying these people.
