"Forever chemicals" are not just a headline, they are a supply chain problem. We sit down with Dr Jerry Shurson from the University of Minnesota to trace how PFAS contamination can start in everyday products and industrial uses, then travel through air and drinking water into soil, crops, livestock feed, and the food we rely on.

We break down what PFAS are, why they persist for so long, and why scientists struggle to answer the question everyone asks: “What, if any, level is safe?” 

With more than 15,000 PFAS compounds in circulation and limited toxicity data for many of them, setting clear dietary guidelines and food safety thresholds becomes incredibly hard. We also explore the One Health stakes, including the links to neurological issues, reproductive harm, and cancers that researchers have associated with PFAS exposure.

A major theme is the circular bioeconomy. Recycling nutrients through manure, compost, and sewage biosolids can be good for sustainability, but it can also recirculate PFAS back into soils where chemicals can accumulate and enter plants and animal-derived foods like meat, milk, and eggs. We talk through what can actually be done today, from water sampling and filtration options like reverse osmosis and activated carbon to asking manufacturers about PFAS use, and why meaningful progress requires coordinated global action plus stronger research funding and regulation.
