First you make sure that the meat is organic, free-ranging. Preferably you raised, hunted, butchered the animal. For some seafood you must 'flash' freeze it first to get rid of the parasites.
Then you eat.
Searing is not raw. It is 'very rare' or 'black and blue'.
There are many ethnic dishes that use raw meat. Some of which are Ethiopian Kitfo, French Steak Tartare, Hawaiian Poke, Italian Carne Cruda or Carpaccio, Japanese Sashimi or Sushi, Mexican Ceviche, and Middle Eastern Kibbeh Naye.
