Salmonella in 2026: What Americans Should Know. Information from Marpeh Urgent Care in Niles, Illinois

Salmonella is a group of bacteria that can cause an infection called salmonellosis, typically involving diarrhea, stomach cramps, fever, nausea, and sometimes vomiting. Symptoms usually appear 6 to 72 hours after exposure and last 4–7 days for most people. 

What makes Salmonella tricky is that it doesn’t change the smell, taste, or appearance of contaminated food. Many infected people recover at home and never get tested, so the true number of cases is far higher than official counts. Salmonella can also survive in surprising environments — from raw foods to dry goods like flour.

National Salmonella Trends in the United States

A CDC report analyzing multistate outbreaks found that Salmonella caused the highest number of multistate intestinal outbreaks in the United States, making up 64% of outbreaks and 90% of illnesses in 2023. This trend has continued into 2025–2026. 

How Salmonella Spreads

Salmonella can move from animals, food, and the environment to humans through raw or undercooked poultry (a major contributor to U.S. cases — over 23%), undercooked beef or pork, eggs, unwashed fruits and vegetables, raw shellfish, contaminated supplements or packaged foods, and contact with pet reptiles, backyard poultry, or other animals.

Even clean‑looking foods can harbor Salmonella — and even healthy‑looking animals can shed it.

Who Is Most at Risk for Severe Illness?

Anyone can get sick from Salmonella. However, severe cases are more common in adults over 65, children under 5, people with weakened immune systems, and pregnant individuals.

CDC data shows that young children and older adults make up a high percentage of outbreak‑associated cases. 

How to Reduce Your Risk of Salmonella Infection

You can’t completely eliminate exposure, but small habits can meaningfully reduce risk — especially for families with young children, seniors, or anyone with a compromised immune system.

Following basic food‑safety steps can help. The CDC recommends four simple principles: Clean, Separate, Cook, and Chill. These include washing hands, preventing cross‑contamination, cooking foods to safe temperatures, and refrigerating leftovers promptly. 

Cooking eggs, poultry, and meat thoroughly is important, as Salmonella dies when heated to safe internal temperatures. Using a food thermometer can be especially helpful for chicken and ground meats.

Being cautious with high‑risk foods — such as raw oysters, raw cookie dough, unpasteurized dairy, and undercooked eggs — can also lower risk. Recent outbreaks continue to show these foods remain common sources.

Washing hands after touching animals is another key step. Backyard poultry, pet reptiles, and even small turtles frequently carry Salmonella and are a leading animal‑related source of outbreaks. 

Checking for food recalls when possible may also help. The FDA and CDC regularly post recall notices for contaminated products, allowing consumers to avoid foods linked to active outbreaks.

These are general food‑safety habits supported by public‑health research — not directives or medical instructions.

When to Seek Medical Attention for Salmonella Symptoms

Most healthy adults recover at home without complications. However, it may be worth contacting a healthcare provider if someone experiences signs of dehydration (such as dry mouth, dizziness, or infrequent urination), diarrhea lasting more than three days, high fever, bloody stools, or difficulty keeping fluids down.

Young children, older adults, and immunocompromised individuals should be monitored more closely during any gastrointestinal illness.
