WASHINGTON — A multistate Salmonella outbreak has expanded to 431 reported cases across 32 states, according to the latest information from the U.S. Centers for Disease Control and Prevention.

The outbreak has been associated with jalapeño peppers, putting fresh produce and food-safety controls under renewed scrutiny. The number of reported infections has increased from 345 cases across 27 states earlier in August.

Federal and state health officials are continuing to investigate the outbreak and trace potentially contaminated food through distribution networks.

Salmonella infections can cause gastrointestinal illness, with symptoms potentially including diarrhea, fever and stomach cramps.

The expanding case count highlights the challenges health officials face when contaminated produce is distributed across multiple states and reaches consumers through different food channels.

Consumers and food businesses should continue following official food-safety guidance while investigators work to determine the full scope and source of the outbreak.
