A) Geographic origin of 8,184 dissected raccoons and the German administrative districts (Landkreise) in which raccoons were harvested during 2017–2018.... During 2008–2018, we collected 8,184 legally harvested or road-killed raccoons from Germany and Luxembourg (Figure, panel A), focusing on different regions every year or every few years, and investigated their intestines for the presence of B. procyonis roundworms. The prevalence of B. procyonis infection in raccoons of the midwestern and northeastern United States reaches 70-82% . Human infections are rare, but can be severe if the parasites invade the eye (ocular larva migrans), organs (visceral larva migrans) or the brain (neural larva migrans). To reduce the risk for B. procyonis infestation, protective measures (procedure masks, gloves, handwashing) should always be applied when raccoons or their feces in the risk area are handled. Baylisascaris procyonis is considered a common cause of clinical larva migrans in animals sharing raccoon ecosystems, and it is usually associated with fatal or severe neurological disease (4–7). SUMMARY The raccoon roundworm, Baylisascaris procyonis , is the most common and widespread cause of clinical larva migrans in animals.
