If it cock-a-doodles, you must not canoodle.

The Centers for Disease Control and Prevention warned people not to “kiss or snuggle” chickens amid a nationwide salmonella outbreak.

In the plucky PSA, the health agency crowed that the bacteria has sickened at least 163 people in 43 states — and warned farmers not get too cozy with the critters.

“Don’t kiss or snuggle backyard poultry, and don’t eat or drink around them,” the CDC wrote on Thursday. “This can spread Salmonella germs to your mouth and make you sick.”

To avoid the fowl infection, the CDC urged poultry handlers to keep sanitizer near coops and frequently wash their hands.

Roughly one third of those who fell ill in recent cases were kids under age 5, who are more likely to experience severe illness or hospitalization from salmonella.

Overall, there were 17 multi-state salmonella outbreaks tied to backyard flock contact in all 50 states last year, the agency said.

“The number of illnesses reported [in 2020] was higher than the number reported during any of the past years’ outbreaks linked to backyard flocks,” the CDC wrote.

The effects of salmonella infection include diarrhea, fever, and stomach cramps.
