The Centers for Disease Control and Prevention (CDC) has announced an investigation into a recent Salmonella outbreak that has affected six states in the United States. The outbreak has been linked to backyard poultry, such as chickens and ducks, which are popular among many Americans for their eggs and as pets.
Outbreak details
As of early May 2025, seven people have been reported sick across six states: Florida, Illinois, Missouri, South Dakota, Utah, and Wisconsin. The CDC has identified that all the infected individuals were exposed to the same strain of Salmonella, which has been previously associated with poultry hatcheries. This strain can be particularly dangerous as it can spread easily through direct contact with the birds or their environment.
Health risks and symptoms
Salmonella is a type of bacteria that can cause serious illness in humans. Symptoms typically include diarrhea, fever, and stomach cramps, which appear six hours to six days after infection. While most people recover without treatment within four to seven days, severe cases can lead to hospitalization. Young children, older adults, and individuals with weakened immune systems are at higher risk of severe illness.
Preventive measures
The CDC has issued several recommendations to help prevent the spread of Salmonella from backyard poultry to humans. These include:
Hatchery practices
The CDC also advises hatcheries to implement best management practices to reduce Salmonella contamination. This includes sourcing poultry from hatcheries that take steps to minimize the risk of infection and ensuring that poultry display areas are cleaned and sanitized between shipments.
Conclusion
The recent Salmonella outbreak serves as a reminder of the potential health risks associated with backyard poultry. By following the CDC’s guidelines, individuals can enjoy the benefits of raising poultry while minimizing the risk of infection. The CDC continues to monitor the situation and will provide updates as more information becomes available.
