"Start the Conversation!" Mad Cow Disease (formally, Bovine Spongiform Encephalopathy) is a degenerative, fatal disease affecting the CNS of adult cattle. It's believed that BSE is caused by a protein gone bad, called a Prion. A similar disease in humans is called variant CJD, and is believed to be caused by eating neural tissues from BSE-infected cattle. Our design depicts a few bad guys glomming on to the good guys, eventually taking over and turning them all-bad. The twig-like structures in the background represent another configuration of these prions. Needless to say, none of this is good for your burger.
