What this means for you
The persistence rating is the standout concern here — these compounds linger in the body and environment for years. The EPA lists dairy products from livestock exposed to PFAS among the routes by which PFAS reach food, alongside fish from contaminated water, and notes that biosolids used on agricultural land can affect animals that graze it. The pathway runs through the land, so it surfaces near known contamination rather than everywhere.
