For example, an individual who develops anxiety or other non-specific symptoms following a minimal pesticide exposure does not need to be reported. On the other hand, illness or exposure does not require laboratory confirmation before reporting. If the affected person resides in Long Beach or Pasadena, contact the respective city health departments. In February 2000, a case of visceral larva migrans due to Baylisascaris procyonis was confirmed in a LAC young adult with eosinophilic meningoencephalitis. When the raccoon ingests roundworm eggs, the larvae migrate through various tissues and end up in the small intestine.
Eggs reach the soil in the feces, and being extremely hardy, can survive in moist soil for years.
This is particularly important for children and pets who play in contaminated soil or eat dirt. Wildlife rehabilitators, animal control officers, and hunters may also be at increased risk. When other animals or humans ingest eggs, they become accidental or dead-end hosts. Control measures should be aimed at making the environment around homes less attractive to raccoons. Raccoons may live in attics and sheds, seeking out garbage cans for food.
