This article is an abstract about how withholding feed from animals before slaughter helps fight carcass contamination. When an animal is fasted before slaughter there is a lower chance of fecal contamination and less visble contamination on the animals hide which makes for cleaner slaughter conditions. The conclusion states that feed should be withheld for 24s to reduce trailer defication and no more than 48 hours to reduce foodborne microbial growth.
