What kills giardia?

* Boil water. Boiling water for at least 1 minute will kill giardia. This is the most effective way to ensure that your water is safe to drink.

* Use a water filter. A water filter that is certified to remove giardia cysts can be used to filter water from a source that may be contaminated. Be sure to follow the manufacturer's instructions for use.

* Use water treatment tablets or drops. Water treatment tablets or drops that contain iodine or chlorine can be used to kill giardia. Be sure to follow the manufacturer's instructions for use.

* Avoid drinking untreated water. This includes water from streams, rivers, ponds, and lakes. If you are not sure if water is safe to drink, boil it first or use a water filter or treatment tablets.

* Wash fruits and vegetables thoroughly before eating them. This will help to remove any giardia cysts that may be present.

* Cook meat thoroughly. Cooking meat to an internal temperature of at least 160 degrees Fahrenheit will kill giardia.

* Practice good hygiene. This includes washing your hands after using the bathroom, after changing a diaper, and before eating.
