Any cooking creates heat-created toxins which harm your body. Marinating does not work. Allegedly, freezing a raw animal food for 14 days before thawing and eating it will ensure removal of all parasites. However, this parasité-phobia is all nonsense. In developed countries, animals are so often dewormed via medicine that there is virtually no chance of getting parasites. Even people like me who eat large amounts of raw wild game hardly ever get parasites, and, if they do, the parasites tend overwhelmingly to be harmless, and are easily gotten rid of by buying anti-parasite drugs from a chemists´, using a prescription.
