Giardia Infection a Common Foodborne & Waterborne Illness


Giardia infection (giardiasis) is one of the most common waterborne diseases in the United States. The parasites are found in backcountry streams and lakes and in municipal water supplies, swimming pools, whirlpool spas and wells. Giardia infection can be transmitted through food, water and person-to-person contact.

Giardia is a parasite found on certain surfaces or in soil, food, or water that has been contaminated with feces from infected carriers. Giardia can survive outside the body for long periods of time and is tolerant to chlorine disinfection.

While the parasite can be spread in different ways, water is the most common transmission mode, most notably in swimming pools, waterways and drinking water.

Prevention: Controlling the Risks of Giardia


Giardia infection is caused by a microscopic parasite that is found worldwide, especially in areas with poor sanitation and unsafe water. Anything that comes into contact with feces from infected humans or animals can become contaminated with Giardia. People may be infected after they swallow the parasite. Giardiasis can be spread in the following manners:

  • Ingesting Giardia picked up from surfaces like bathroom handles, changing tables, diapers, or toys
  • Drinking water or using ice made from water sources where Giardia may thrive
  • Swallowing water while swimming where Giardia is present
  • Eating uncooked food that contains Giardia
  • Close contact with someone who is ill with giardiasis
  • Traveling to countries where giardiasis is endemic

Giardia infections usually clear up within a few weeks though intestinal problems may persist long after the parasites are gone. Several drugs are effective against giardia parasites, but not everyone responds to them. Prevention is the best defense.

  • Watery, sometimes foul-smelling diarrhea
  • Fatigue
