This year saw the largest number of illnesses linked to contact with backyard poultry ever recorded by the U.S. Centers for Disease Control. Contact with live poultry or their environment can make people sick with Salmonella infections. Live poultry such as chickens and ducks can be carrying Salmonella bacteria but appear healthy and clean, with no sign of illness.
As raising backyard flocks becomes more popular, more people are having contact with chickens and ducks – and may not know about the risk of Salmonella infection.
These outbreaks are a reminder to follow steps to keep your family healthy while enjoying your backyard flock.
Always wash hands thoroughly with soap and water right after touching live poultry or anything in the area where the birds live and roam.
Adults should supervise handwashing for children.
Do not let live poultry inside the house.
Do not let children younger than 5 years handle or touch chicks, ducklings, or other live poultry without adult supervision.
