The Death of Buddha: A Medical Enquiry:

The death of the Buddha (Siddhartha Gautama) has been depicted widely in Buddhist iconography. The Buddha is generally shown with a serene or smiling expression, lying on his right side and resting his head on his right hand. The dates of Buddha's life traditionally are given as 566–486 BC. Buddha died from an illness, the nature of which remains unsettled. The present paper examines a variety of sources and concludes that it was tainted pork that led to his demise. He succumbed to the disease pig-bel, a necrotizing enteritis caused by the toxins of Clostridium perfringens infection.
