The California Department of Public Health is warning people about the risks of contact with live poultry.

The Department issued a warning that in recent year’s people keeping backyard flocks of chickens and ducks has caused the spreading of salmonella infection. Officials say that baby chicks and ducklings may have salmonella in their feces and bodies.

According to the U.S. Centers for Disease Control and Prevention at least 372 people in 47 states nationwide since the start of the year have been infected. Twenty-one residents have been from California.

If you come in contact with live poultry wash your hands. People should also prevent live chickens, ducks and geese from coming into their homes and should not allow children under 5 to handle live poultry or eggs without supervision.

Nationwide, 71 people have been hospitalized from the infections, but no deaths have been reported.
