Mark Purdey was born in the village of Much Hadham in the UK. He is a descendent of the globally renowned "Purdey shotgun" family and attended London University to study zoology and psychology. In his mid twenties, he pioneered an organic dairy farm on which he bred up a herd of pedigree Jersey cattle. The breeding was designed to produce cattle that demonstrated longevity and an ability to produce milk from a self-sufficient system with minimal reliance upon feed. Mark initiated research into the environmental prerequisites of transmissible spongiform encephalopathies after BSE erupted in four cows that he had purchased. None of his farm bred cows ever contracted BSE. His investigative journey into the origins of Mad Cow has been featured on several UK television documentary films, and Mark has been invited to address many UK government scientific advisory committees.
Making his first appearance on C2C, ecologist and organic farmer, Mark Purdey shared his theory on BSE (Mad Cow Disease). Through his studies, he has concluded the illness is actually caused by levels of metal micro-crystals in the environment that bind up with prion proteins to form a crystal structure in the brain "that is the hallmark of the disease."
