   Hygiene

   In countries where roundworms are common, roundworms may be prevented by eating only cooked food and by avoiding green vegetables and salads. It is best if children do not play in areas of poor sanitation, or where human stool (faeces) is used as fertiliser. Always wash hands before eating or preparing food, and after going to the toilet or changing nappies.

   Medication

   If there is a high risk of infection, taking preventative medicine may be advised. For example, if you stay in an area known to be contaminated, or if you travel abroad to at-risk areas.
