Angiostrongylus cantonensis is known to be a major cause of eosinophilic meningitis in humans who have eaten raw or improperly cooked snails or slugs that are infected with the parasite. The parasite can also affect rats, birds, horses, dogs, and other non-human primates after they eat the larvae of snails and slugs.
