 WWhat Are Salmonella Bacteria?

Salmonella are microscopic, rod-shaped bacteria that can infect people and animals. More than 2,500 serotypes have been identified. Salmonella Javiana—the type involved in the 2026 jalapeño outbreak—is one serotype; a serotype is not the same thing as a single outbreak strain.

People usually become infected by swallowing contaminated food or water or by contact with infected people, animals, or their environments. Food contaminated with Salmonella often looks, smells, and tastes normal. Contamination can occur during growing, processing, distribution, preparation, or service.

The CDC estimates that Salmonella causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths in the United States each year. Most infections are foodborne, and only about one in 30 is diagnosed.

How Does Salmonella Cause Illness?

The illness caused by non-typhoidal Salmonella is called salmonellosis. Symptoms usually begin six hours to six days after exposure and often include diarrhea, fever, and stomach cramps. Most people recover in four to seven days, but some develop dehydration, colitis, bacteremia, sepsis, meningitis, reactive arthritis, or infection in other parts of the body.

How Do Investigators Identify a Salmonella Outbreak?

Clinical laboratories test patient specimens. Public-health laboratories can use whole genome sequencing to compare Salmonella isolates and identify closely related illnesses. Investigators combine sequencing with symptom timing, interviews, restaurant or purchase clusters, traceback, supplier records, and food or environmental testing. A genetic relationship can support a common source, but it does not identify the food or responsible company by itself. Read our Salmonella outbreak lawsuit FAQ.

Current Example: Salmonella Javiana Linked to Jalapeños

In August 2026, CDC and FDA linked a 32-state Salmonella Javiana outbreak to recalled fresh jalapeños grown in Sinaloa, Mexico, and distributed by Coast Citrus Distributors. Investigators identified restaurant exposures and clusters involving Chipotle and QDOBA. Read the current jalapeño Salmonella outbreak report for the latest case count, affected states, recall information, and patient actions.

When Can Salmonella Lead to a Legal Claim?

A claim requires evidence that the illness and losses can be connected to contaminated food, a restaurant, or another legally responsible source. Medical testing, meal or purchase records, outbreak data, traceback, and the severity of the harm may all matter. Read the Salmonella lawsuit guide to understand the proof lawyers evaluate.
