Which food is NOT a common source of E. coli O157:H7?

Cooked chicken is considered a safe food product in relation to E. coli O157:H7 because proper cooking kills harmful bacteria that may be present. E. coli O157:H7 is typically associated with undercooked or raw foods, particularly those that are animal-based or come into contact with fecal matter.

Raw beef is a known risk, as ground beef can be contaminated during processing. Alfalfa sprouts can become contaminated due to poor agricultural practices or contaminated water. Unpasteurized fruit juices also pose a risk due to the potential presence of E. coli from contaminated fruits. These foods are more commonly linked to outbreaks of E. coli O157:H7, while cooked chicken, when handled and cooked properly, is generally much safer.
