Before the “Bodies Revealed” exhibition opened, Union Station officials reassured a queasy public by producing the English translation of a donor consent form.

CEO Andi Udris said the form showed that the cadavers in the Kansas City exhibit all came from persons in China who had given permission for their bodies to be used for scientific education.

Shortly after the exhibit opened, station officials learned the form wasn’t authentic. They showed poor judgment by not immediately sharing that knowledge with the public.

Udris says he remains confident that the bodies in the Kansas City exhibit were donated with consent. He acknowledges, though, that he has no way to prove that.

The recent revelation is one more reason to urge Congress to investigate the traveling exhibits that display plasticized human skeletons and body parts.

Producers should have to document where they obtained the bodies and prove they were donated willingly.

Union Station officials say they were initially shown the donor form by an employee of Premier Exhibitions, the exhibit’s producer.That person said it was an English translation of the actual form used by the supplier of the cadavers.

The Catholic Key informed station officials in March that the form was actually from an unrelated business.

Udris said he consulted with Premier Exhibitions, which produced an affidavit from the supplier insisting that all of the bodies in the Union Station exhibit were obtained with donor consent.

That now looks like a questionable basis for trust. As the “Bodies Revealed” exhibit prepares to close its Kansas City showing on Monday, it’s dismaying that new doubts have arisen about the cadavers.
