What is the common source of Salmonella typhimurium infection?

Salmonella typhimurium is a significant cause of foodborne illness, and poultry products are known to be a common source of this infection. Poultry can be contaminated during processing or from environmental sources, leading to Salmonella bacteria being present in undercooked or raw chicken and turkey. This is particularly prevalent because poultry can carry Salmonella in their intestines without showing any signs of illness, making it an insidious source of infection.

While undercooked beef, raw eggs, and contaminated water can also be sources of Salmonella infections, Salmonella typhimurium has a strong association with poultry products. The CDC and health safety guidelines emphasize the importance of properly cooking poultry to eliminate the risk of Salmonella infections, which is why this source is highlighted in relation to Salmonella typhimurium.
