Ninety-three people have been sickened by a nationwide salmonella outbreak, but a source of the cases has not been confirmed yet, health officials said.

The outbreak involving salmonella bareilly, an unusual type, has been reported in 19 states and the District of Columbia, according to the Centers for Disease Control and Prevention. The illnesses began between Jan. 28 and March 23, the agency said.

Ten people were hospitalized across the country, but no deaths have been reported. New York had 23 cases, the most of any state, followed by Illinois, Wisconsin and Maryland with eight each. A food source for the salmonella has not been confirmed, but many of the people who were sick reported eating sushi, sashimi or similar foods in the week before symptoms began, the CDC said in a statement.

Salmonella infections often cause diarrhea, fever and abdominal cramps within 12 to 72 hours, according to the CDC. Symptoms usually last four to seven days. Most people recover without treatment, but severe cases can be fatal if not treated quickly with antibiotics, according to the agency.
