Pigs become infected after ingestion of livers and lungs from chickens infected with Ascaris of pig origin.
An experimental infection with Ascaris of pig origin showed that Ascaris suum larvae can migrate extra-intestinally in chickens. Furthermore, after feeding piglets with Ascaris infected chicken liver and lungs, it was possible to recover larvae from their lungs. These observations suggest that the chicken could serve as a paratenic host for Ascaris. There is also the possibility for zoonotic transmission if raw chicken livers are consumed by humans.
