Salmonella outbreak linked to backyard chickens prompts CDC investigation

The Centers for Disease Control and Prevention (CDC) is conducting an investigation into a Salmonella outbreak that is linked to backyard poultry.

Salmonella is a bacteria that can cause people to experience diarrhea, fever and stomach cramps. Symptoms can appear between six hours and six days of infection and will last for four to seven days, the CDC said.

The CDC alert came after an investigation showed backyard poultry - including chickens and ducks - have sickened 109 people, including 33 who were hospitalized.

    • You can use hand sanitizer if soap is not available.

  • Keep yourself and your areas clean to prevent a potential infection.

    • Don't kiss or hug the animals.

    • Don't eat or drink around them.

    • Clean the supplies you use to care for them outside of your house.

    • Don't wear the shoes you wear in the coop inside of your house.

  • Keep an eye on children around the animals.

    • Don’t let children younger than 5 years old touch the animals.
