From a local lab report: Ascarid (roundworm) migration was the cause of a sudden onset of neurological signs-head tilt, and left side paralysis of a six week old chicken. A large granularnatous lesions were also seen in the lungs. The submitting veterinarian indicated the owner had a problem with raccoons. Baylsacaris procyonis is a ubiquitous roundworm in raccoons and when the roundworm egg is ingested by other hosts (including children), larvae develop from eggs and migrate through the internal organs, frequently penetrating the brain. Keeping chickens, children and other animals away from raccoon fecal material is extremely important.
