Can DNA be extracted from a fart?

What kind of a fart. A burny fart might emit some dampness. Whereas a fart that had been held in for a prolonged lenght of time is more questionable....

See google "Trying to hold it in leads to a build-up of pressure and major discomfort. A build-up of intestinal gas can trigger abdominal distension, with some gas reabsorbed into the circulation and exhaled in your breath. Holding on too long means the build-up of intestinal gas will eventually escape via an uncontrollable fart."

A very good question all the same @sam t smith. Look forward to seeing your next threads - hoping they are just as interesting

If the assailant had consumed a particularly rich and pungent meal before the attack, lets say a vindaloo, would this affect the forensic integrity / completeness of the available DNA sample?
