Is fermented cod liver oil truly a safe product? It is hard to imagine how it possibly could be, given what’s known about omega-3 polyunsaturated fats and how prone they are to oxidation and rancidity. It defies scientific facts to believe that it’s safe.

Cod liver oil has a low antioxidant content compared to shark liver oil and a history of being prone to rancidity. Archie Welch discusses the history of cod liver oil in another important interview in this series on the hazards of fermented cod liver oil.

What is the effect of prolonged exposure to warm temperatures on the fragile omega-3 fats present in cod liver oil? Won’t prolonged exposure to warm temperatures and oxygen inevitably lead to a product that contains rancid oils that are unsafe to consume?

Cod liver oil should be kept in the refrigerator or freezer to keep it as cold as possible so that it will stay fresh and not go rancid. How, then, is it possible to ferment cod liver oil at warm temperatures for long periods of time and it not go rancid?

According to Dr. Ron Schmid, the world’s leading lipid scientists say that so-called fermented cod liver oil is the most rancid oil they’ve ever seen. Rancid oil is very dangerous. Did Dr. Ron Schmid die as a result of ingesting this obviously rancid oil?
