The U.S. Centers for Disease Control and Prevention said on Wednesday that a salmonella outbreak linked to jalapeno peppers has infected 431 people across 32 states, up from 345 cases in 27 states reported earlier this month.
U.S. health authorities are currently investigating a multistate outbreak of salmonella javiana infections, with the CDC reporting a total of 431 infections, 57 hospitalizations and no deaths, as of August 19.
According to the CDC, illnesses began between June 19 and August 2.
Salmonella is a group of rod-shaped bacteria that can cause salmonellosis, a common foodborne illness. Symptoms typically include diarrhea, fever and abdominal cramps.
The infections have been linked to jalapeno peppers from Sinaloa, Mexico, distributed by Coast Citrus Distributors.
91 percent of people interviewed reported eating at a Mexican-style restaurant before their illness, including at Chipotle Mexican Grill and QDOBA, the CDC said.
Chipotle switched its jalapeno supplier, while QDOBA restaurants ceased using the ingredient.
The salmonella outbreak comes as U.S. health officials also investigate a multistate cyclosporiasis outbreak linked to lettuce supplied by Taylor Farms, a major food-service producer.
The CDC estimates salmonella causes more than 1 million foodborne illnesses in the United States every year.
