As resident Canada goose (Branta canadensis) populations increase throughout North America, so do the health and environmental risks associated with goose feces. Previous studies suggest that goose feces may be a conduit for transmitting Giardia, a protozoan that is parasitic to humans. We surveyed fecal droppings from free-ranging resident Canada geese for Giardia spp. at 9 sites in the Triangle area (Raleigh, Durham, and Chapel Hill) of North Carolina in 2007 and 2008. Samples (n = 234) were tested using the ProSpect® Giardia EZ Microplate Assay, and there were no positives. Our results indicate that risk of zoonotic giardiasis from Canada goose feces in the Triangle area of North Carolina is low.
