Nutritional Medicine , Separating Fact from Fiction
In a landmark study published in the Journal of Alzheimer’s Disease, study researchers Friedland and co-authors suggested that farmed fish could transmit Creutzfeldt Jakob disease, or what is commonly known as mad cow’s disease. This is the same disease found also in chronic wasting disease associated with the deer population and caused by prions.
Farmed fish are typically fed a diet of rendered cow’s meat and bone meal, a practice that should be prohibited according to Friedland. “Fish do very well in the sea without eating cows”, he stated.
Although there is a question of whether the species barrier would prevent such transmission, it is possible for the disease to be spread by eating a carrier that is not infected itself. It is also a possibility that eating cow parts that are infected could cause fish to experience a pathological change in the fish that allow the infection to be passed between the two species.
Although such a transmission has not been proven, the incubation period of mad cow’s disease may last for decades – a factor that makes causality difficult to prove. The question is, do you want to take the chance??? According to Friedland, enhanced safeguards should be put into effect and this is potentially a public health issue.
