CDC Warns of Multi-State Salmonella Outbreak Linked to Backyard Poultry
On April 23, 2026, the U.S. Centers for Disease Control and Prevention (CDC) issued an urgent investigation notice regarding a growing Salmonella outbreak tied to backyard poultry, spanning 13 states and sickening dozens. The outbreak, caused by the Salmonella Saintpaul strain, has already resulted in 34 confirmed illnesses, with 13 hospitalizations—though health officials warn the true number of cases is likely far higher. As backyard flocks continue to rise in popularity, the CDC is urging owners to take immediate precautions to prevent further spread of the bacteria, which can be carried by seemingly healthy birds.
Dr. Helena Fischer, Editor of Health at World Today Journal, explains: “This outbreak is a stark reminder that even well-cared-for poultry can harbor dangerous pathogens. Salmonella doesn’t discriminate—it can affect anyone, from seasoned farmers to families keeping a few hens for fresh eggs. The CDC’s guidance isn’t just about protecting your birds; it’s about safeguarding your household, especially young children and immunocompromised individuals who are most vulnerable.”
The outbreak underscores a broader public health challenge: the intersection of animal husbandry and human health. While backyard poultry offer benefits like sustainable food sources and educational opportunities, they also introduce risks that many owners may underestimate. The CDC’s investigation highlights how easily Salmonella can spread from birds to humans—through direct contact, contaminated environments, or even unwashed hands after handling eggs or coop supplies.
Scope of the Outbreak: What We Know So Far
As of the CDC’s latest update, the outbreak has affected residents in 13 states, with illnesses reported between February 26 and March 31, 2026. The states with confirmed cases include:
- Florida
- Illinois
- Indiana
- Kentucky
- Maine (3 cases)
- Maryland
- Michigan
- Mississippi
- Latest Hampshire (1 case)
- Ohio
- Tennessee
- West Virginia
- Wisconsin
Of the 34 confirmed cases, 13 individuals have been hospitalized, though no deaths have been reported. However, the CDC cautions that these numbers represent only a fraction of the true impact. “Many people recover from Salmonella without medical care and are never tested,” the agency notes in its official outbreak report. It can take three to four weeks for new cases to be linked to the outbreak, meaning recent illnesses may not yet be reflected in the data.
Epidemiological evidence strongly points to backyard poultry as the source of the outbreak. Of the 29 individuals interviewed by the CDC, 23 reported contact with backyard flocks. Among the 14 who owned poultry, 13 had acquired birds since January 1, 2026, suggesting a potential link to recent purchases. The CDC is currently tracing the origins of these birds, including the hatcheries and agricultural retail stores where they were sourced, though no specific suppliers have been named in the investigation.
How Salmonella Spreads from Poultry to People
Salmonella bacteria are naturally present in the intestines of poultry and other animals, and birds can carry the germs without showing any signs of illness. The bacteria are shed in their feces, which can then contaminate their feathers, beaks, feet, and the environments where they live—including coops, feeders, and even eggshells. Humans can become infected through several common pathways:
- Direct contact: Handling birds, chicks, or ducklings, especially if hands are not washed afterward.
- Indirect contact: Touching surfaces or objects contaminated with Salmonella, such as cages, water bowls, or coop bedding.
- Environmental exposure: Walking through areas where poultry roam, even if you don’t touch the birds directly.
- Egg handling: Collecting or cleaning eggs without proper hygiene practices.
The CDC emphasizes that Salmonella infections are not limited to those who keep poultry. Visitors to homes with backyard flocks, including children, can also be exposed if they come into contact with contaminated areas or objects. Symptoms of Salmonella infection typically appear 6 hours to 6 days after exposure and may include:
- Diarrhea (sometimes bloody)
- Fever
- Stomach cramps
- Nausea or vomiting
- Headache
While most healthy adults recover within a week, severe cases can lead to dehydration, hospitalization, or even life-threatening complications, particularly in high-risk groups. The CDC warns that children under 5, adults over 65, and individuals with weakened immune systems are at the greatest risk for severe illness.
CDC’s Safety Recommendations for Backyard Flock Owners
In response to the outbreak, the CDC has issued a set of detailed guidelines to help backyard poultry owners minimize the risk of Salmonella transmission. These measures are designed to protect both the birds and the humans who care for them:
- Hand hygiene: Wash hands thoroughly with soap and water for at least 20 seconds after any contact with poultry, their eggs, or their environment. If soap and water are unavailable, apply hand sanitizer.
- Dedicated footwear: Wear shoes or boots specifically for the coop, and avoid wearing them inside the house to prevent tracking germs indoors.
- Keep poultry outdoors: Do not allow birds or their supplies (feeders, waterers, etc.) inside the home, including garages or porches.
- Supervise children: Children under 5 should not handle poultry, chicks, or ducklings, or enter areas where birds live and roam. Older children should be supervised and taught proper handwashing techniques.
- Safe egg handling: Collect eggs frequently to prevent them from becoming dirty or cracked. Refrigerate eggs promptly and cook them thoroughly before eating. Do not wash eggs with warm water, as this can pull bacteria into the shell.
- Clean and disinfect: Regularly clean and sanitize poultry equipment, such as feeders and waterers. Use a disinfectant approved for use around animals.
- Avoid kissing or snuggling birds: While it may be tempting, especially with chicks, avoid close facial contact with poultry to prevent the transfer of germs.
The CDC has also released a series of educational videos demonstrating safe handling practices for backyard poultry. These resources are particularly valuable for new flock owners who may be unfamiliar with the risks.
Advice for Businesses and Retailers
The outbreak has prompted the CDC to issue recommendations for businesses that sell live poultry, including agricultural retail stores and hatcheries. These guidelines aim to reduce the risk of Salmonella contamination at the source and educate customers about safe handling practices:
- Source responsibly: Obtain poultry from hatcheries that implement Salmonella reduction programs, such as those participating in the National Poultry Improvement Plan (NPIP).
- Sanitize display areas: Clean and disinfect poultry display areas between shipments to prevent cross-contamination.
- Provide handwashing stations: Place handwashing stations or hand sanitizers near poultry display areas and encourage customers to use them before and after handling birds.
- Educate customers: Display signage with safety tips and distribute informational materials about Salmonella risks and prevention.
- Limit high-risk interactions: Discourage practices that increase exposure, such as allowing children to handle chicks in store displays.
Who Is Most at Risk?
While anyone can contract Salmonella, certain groups are more susceptible to severe illness and complications. The CDC highlights the following high-risk populations:
- Children under 5: Young children are more likely to put their hands or objects in their mouths, increasing the risk of infection. Their immune systems are also still developing, making it harder for them to fight off the bacteria.
- Adults over 65: Older adults are more likely to have underlying health conditions that weaken their immune response, making them more vulnerable to severe Salmonella infections.
- Immunocompromised individuals: People with weakened immune systems, such as those undergoing chemotherapy, living with HIV/AIDS, or taking immunosuppressive medications, are at higher risk for complications.
- Pregnant women: While Salmonella infections are not typically more severe during pregnancy, they can lead to dehydration, which may pose risks to both the mother and the developing fetus.
For these groups, the CDC recommends extra precautions, such as avoiding contact with backyard poultry altogether or ensuring strict adherence to hygiene practices if contact is unavoidable.
What Happens Next?
The CDC’s investigation into the outbreak is ongoing, with a focus on tracing the source of the contaminated poultry and identifying any common suppliers or hatcheries. The agency is collaborating with state health departments, the U.S. Department of Agriculture (USDA), and other partners to gather additional data and prevent further spread of the bacteria.
In the meantime, the CDC is urging flock owners to remain vigilant and follow its safety guidelines. The agency plans to provide updates on its outbreak webpage as new information becomes available. The next official update is expected within the coming weeks, though the timing may vary depending on the progress of the investigation.
For those who suspect they may have been exposed to Salmonella, the CDC recommends seeking medical attention if symptoms develop, particularly if they persist for more than a few days or are accompanied by high fever, bloody diarrhea, or signs of dehydration. Early treatment with fluids and, in some cases, antibiotics can help prevent complications.
