U.S. health officials say Mexican papayas tainted with salmonella have sickened 99 people in the United States.

The Centers for Disease Control and Prevention said Tuesday that the outbreak was reported in 23 states between January 1 and July 22. Most of those cases are in Texas. No deaths have been reported.

Officials say the papayas were imported from Mexico by Agromod Produce of McAllen, Texas. The company has issued a voluntary recall of fresh, whole papayas because of the potential for salmonella contamination.

The CDC, along with the Food and Drug Administration and public health officials from several states, are investigating the outbreak.

Salmonella poisoning usually causes diarrhea, fever and abdominal cramps within 12 to 72 hours after infection. Officials say symptoms can last up to a week and that most people can recover without treatment. In severe cases, salmonella poisoning can lead to hospitalization.
