What primary biological hazard can migrate to the human central nervous system after ingesting infected Cornu aspersum raw?
Answer
Angiostrongylus cantonensis (rat lungworm)
The most significant parasitic threat associated with eating snails raw or improperly cooked is Angiostrongylus cantonensis, commonly referred to as the rat lungworm. If this parasite is consumed alive, it has the potential to cross the blood-brain barrier and reach the human central nervous system. This migration can lead to a severe neurological condition known as eosinophilic meningitis, characterized by inflammation caused by a specific type of white blood cell responding to the invading parasite, resulting in potentially severe symptoms.
