How can giardiasis be prevented?

  • Drink only water that has been treated in established treatment facilities.
  • If there is any doubt about the adequacy of the treatment of water, boil the water or filter it through a filter with a pore size of <1 micrometer, which will exclude trophozoites and cysts.
  • Do not drink from fresh water streams or lakes without boiling or filtering the water.
  • Do not use ice or drink beverages made from tap water that may be contaminated.
  • Do not brush teeth with tap water that may be contaminated.
  • Do not eat uncooked or unpeeled fruits or vegetables grown in conditions in which contamination with Giardia might occur.
  • Wash hands before eating food, after changing diapers, using the bathroom, or touching pets.
  • Avoid oral/anal sex.
