An example of a body demonstrating relatively advanced decomposition, with bloating, skin discoloration, and abundant purge fluid.
The decomposition of the gastrointestinal tract results in a dark, foul-smelling liquid called “purge fluid” that is forced out of the nose and mouth due to gas pressure in the intestine. Putrefaction begins immediately upon death and usually becomes noticeable within 24 hours. As soon as death occurs, the bacteria or microorganisms within the intestinal tract escape from the bowel into the other tissues of the body. As they grow, they begin to produce gases and other properties that distort and discolor the tissues of the body.
