Salmonella outbreak more than doubles; CDC identifies potential source - USA TODAY

A recent salmonella outbreak with no known food source has more than doubled in infections in over a week. .

15, the Centers for Disease Control and Prevention reported 127 people in 25 states had been infected with salmonella, resulting in 18 hospitalizations.

No food source has been attributed to the outbreak, but state and local officials from infected states have collected food samples from restaurants where sick people ate and found salmonella in a condiment cup containing cilantro and lime.

Health officials also believe true number of infections is much higher than reported as some people recover from salmonella without medical care and therefore are not tested for it.

The CDC recommends people practice food safety measures such as cleaning utensils, hands and foods, as well as separating different foods and making sure all food is cooked to a high enough temperature. The agency also recommends refrigerating perishable foods within two hours and thawing foods in a refrigerator
