AlabasterAnthem: Just like reptiles, chickens have Salmonella bacteria in their digestive tract. Adaptation in both the bacteria and animal has resulted in a situation where infection is often asymptomatic. Issues arise, however, when slaughtering and processing isn’t done in a sanitary way.
Because the Salmonella lives in the chicken’s digestive tract, it can also be found in droppings. What we find is that the primary cause of Salmonella infection in chicken meat is faecal matter coming in contact with the meat during the slaughtering process, or while it’s being handled for shipping.
PopeliusJones: Salmonella is found in the environments that chickens live, and is present in all sorts of things. Rats, mice, other birds, and flies can all carry the various salmonella bacteria, and they frequent the same places that chickens live. As for the eggs, some time a while back, the salmonella bacterium figured out how to cross the barrier into eggs while still inside the chicken, making them potentially dangerous. It’s this danger that we focus on, not necessarily the chicken meat
