A paper by Mario Baldi et al. in the framework of his PhD

Baylisascaris procyonis (Ascaridoidea: Ascarididae) parasites are facultatively heteroxenous nematodes that are widely distributed in the United States and Canada, where prevalence rates reach 70%–90%. They colonize the small intestine of their final host, the northern raccoon (Procyon lotor), whose feces can contain up to 25 × 103 eggs/g. Under ideal environmental conditions (100% humidity and 24°C), eggs become infective in soil (1,2). When ingested by other mammalian hosts, third-stage larvae can produce pathologic changes called larva migrans, which can lead to chronic neurologic disorders and even death (1,3). B. procyonisparasite infection of humans occurs by the fecal–oral route (ingestion of eggs in contaminated food) (1). Small children are particularly vulnerable through accidental geophagia. Public health concerns arise where raccoon and human populations overlap. Read paper
