As Halloween approaches, CDC warns that pet chickens should be handled carefully CDC: "Don't kiss your birds or snuggle them and then touch your face or mouth."

Louisiana resident Stephanie Morse treats chickens like family, and like any other family member, Morse’s chickens get costumes every Halloween.

"Their bare skin is exposed, I just like to put a sweater on them to keep them warm and comfortable, and some of them have more personality," Morse told CBS affiliate KNOE-TV.

When dressing a chicken, whether in a Halloween costume or a sweater, it is easier for a person to come into contact with harmful bacteria that live on poultry, including salmonella, health experts say.

The CDC is asking pet owners to use caution when handling their feathered friends due to a particular strain of salmonella.

At least 92 people in 29 states have been infected with a strain of multidrug-resistant salmonella after coming into contact with raw chicken products. No deaths have been reported, but 21 of the sick patients have been hospitalized.

The CDC warned that people could be infected by handling live chickens.

Additional guidance includes: • Always wash your hands after touching chickens or anything in their environment. Running water and soap are best. Use alcohol-based hand sanitizer if soap and water aren’t available, and wash your hands thoroughly when you get to a sink. • Keep chickens outdoors. Never bring them in your house. • Don’t eat or drink in the area where the birds live or roam. • Don’t kiss your birds or snuggle them and then touch your face or mouth. • Children under 5 years old should not hold or touch chickens. Young children are more likely to get sick because their immune systems are still developing and they are more likely to put their fingers or pacifiers and other items into their mouths.
