Eating deli meat and touched 12 week old son pacifier then not thinking put in his mouth! can he get listeria from this contact?

Well baby exam: Listeria infection is most commonly contracted via eating improperly processed deli meats & unpasteurized milk, so keep in mind your deli meat probably is not infected with listeria. But to be in the safe side take your 12 yo son for a well baby check-up & in the future always be more careful about food hygiene and overall hygiene in dealing with your son. I hope for good health for both of you!
