While the threat of mercury and PFOS are real concerns, there MAY be factors in your harvest that lesson the overall impact of consumption by you and/or your family members. The study conducted and reported on in the link above involves LOCAL waterfowl. It may, or may not, be indicative of mercury or PFOS levels in waterfowl migrating into Utah from other environments such as regions north of here. Also, some of your waterfowl may come from other regions of the world from guided or free lance hunts in other regions.
For example, last year I hunted waterfowl in Utah, Texas, Arkansas, & Canada. This year I will pursue waterfowl in Utah, Texas, and Alaska. As to consumption, 99% of my waterfowl meat is ground and either made into breakfast sausage or canned (pressure cooked in glass jars). Therefore, the actual level of mercury or PFOS in my processed meat is unknown. However, I generally don't consume more than a couple of meals a month that contain my processed waterfowl meat.
YMMV!
