Causes, Risk Factors, And Complications Of Giardiasis

Consuming Contaminated Food

Eating food infested with the giardia parasite can lead to giardiasis. However, consuming contaminated food is a less likely route of infection than other methods. This is because heating and cooking food kills the parasite. Infection from contaminated food would be a major concern if eating raw foods, foods not cooked to a high temperature, or foods that may have been washed with contaminated water. Food placed on unclean surfaces that may have come into contact with the parasite is also an infection risk. Improper food handling and hygiene practices by individuals who may have giardiasis can also transmit the infection.
