Prevention & Control

The best way to prevent ascariasis is to always:

  • Avoid ingesting soil that may be contaminated with human feces, including where human fecal matter ("night soil") or wastewater is used to fertilize crops.
  • Wash your hands with soap and warm water before handling food.
  • Teach children the importance of washing hands to prevent infection.
  • Wash, peel, or cook all raw vegetables and fruits before eating, particularly those that have been grown in soil that has been fertilized with manure.
