Salmonella Cases Spread To 16 States

Salmonella food poisoning first linked to uncooked tomatoes has spread to 16 states, federal health officials said Saturday.

Investigations by the Texas and New Mexico Departments of Health and the U.S. Indian Health Service have tied 56 cases in Texas and 55 in New Mexico to raw, uncooked, tomatoes.

"We're seeing a steady increase," Deborah Busemeyer, New Mexico Department of Health communications director, said Saturday.

An additional 50 people have been sickened by the same Salmonella "Saintpaul" infection in Arizona, California, Colorado, Connecticut, Idaho, Illinois, Indiana, Kansas, Oklahoma, Oregon, Utah, Virginia, Washington and Wisconsin, the federal Centers for Disease Control and Prevention reported.

Investigators are trying to determine if raw tomatoes also are responsible for the illnesses in those states, said Arleen Porcell, a CDC spokeswoman.

In reponse to the problem, the FDA has issued a tomato warning to consumers in all 50 states, reports CBS News correspondent Nancy Cordes.

The source of the tomatoes responsible for the illnesses has not been pinpointed, but health officials in Texas and New Mexico said none of them was grown in those two states.

At least 23 people have been hospitalized, and no deaths have been reported, she said. Patients ranged in age from 1 to 82.

The rarity of the Saintpaul strain and the number of illnesses "suggest that implicated tomatoes are distributed throughout the country," she said.

Interviews conducted with 73 people found the illnesses began between April 16 and May 27, Porcell said.

Salmonella is a bacteria that lives in the intestinal tracts of humans and other animals. It usually is transmitted to humans by eating food contaminated with animal feces.

Most infected people suffer fever, diarrhea and abdominal cramps starting 12 to 72 hours after infection. The illness tends to last four to seven days. Many people recover without treatment, but severe infection and death is possible.
