A glass of fresh orange juice is packed with vitamin C--essential for fighting colds and healing wounds--but how about a potentially lethal germ? Last fall, 500 Americans fell ill (and one died) from drinking OJ that hadn't been pasteurized, a process that uses heat to kill microorganisms in food and drink.

The culprit, say experts at the U.S. Centers for Disease Control (CDC), is Salmonella, a bacteria (single-celled organism) that can thrive in unpasteurized juices and cause a slew of symptoms like stomach cramping, fever, and life-threatening diarrhea. "Not all unpasteurized juice contains salmonella," says Josefa Rangel, a CDC epidemiologist (scientist who studies the cause and spread of infections). But if you want to reduce your risk of contracting the bacteria, drink orange juice that is labeled "pasteurized" or "from concentrate."


The process of pasteurization is named for French scientist Louis Pasteur (1822-1895).
