Giardia found in pond at Pitt Meadows park

This waterborne parasite, which is the most common intestinal parasite in Canada, can lead to some pretty nasty symptoms, including gas, diarrhea, dehydration, abdominal cramps, and nausea or vomiting. It is especially important to keep children away from the pond or to thoroughly wash their hands if they do come in contact with the water since children up to nine years old are most at risk of developing giardia symptoms, according to the Public Health Agency of Canada.
