5- Parasitic meningitis (Eosinophilic meningitis):
A rare condition caused by the parasites: angiostrongylus cantonensis, baylisascaris procyonis (known as neural larva migrans), and gnathostoma spinigerum.
These parasites typically infect animals, but humans may contract the infection by eating infected animal tissues or contaminated food (usually raw fish and snails).
How do you catch these parasitic infections?
Eating raw food: Raw or undercooked freshwater fish, eels, frogs, poultry, snakes, snails, or slugs may be contaminated with these parasites.
Eating contaminated food: Food contaminated with raccoon feces may contain B. procyonis eggs.
