A stool culture is done to: 1  Find the cause of symptoms. 2  Find and identify certain types of organisms that are causing infections or diseases. 3  Identify a person who may not have any symptoms of disease but who carries bacteria that can spread infection to others. 4  Find out if treatment for an infection has worked as it should.
Meat may stay in the intestines for 24-72 hours and still depend on its type. Likewise, red meat in particular takes 1-3 days to complete the digestion process because of fat content and high protein, according to Lisa Cicciarello Andrews of University of Cincinnati.
Humans can't actually digest meat: it rots in the colon.. And its variant: Meat takes 4-7 days to digest, because it has to rot in your stomach first.. (Some variations on this myth claim it takes up to two months!) Like most vegetarian propaganda, it's not just false, it's an inversion of truth.
