Harmful bacteria are the most common cause of foodborne illness. Foods may have some bacteria on them when you buy them. Raw meat may become contaminated during slaughter. Fruits and vegetables may become contaminated when they are growing or when they are processed, but it can also happen in your kitchen if you leave food out for more than 2 hours at room temperature.
