"All of the food epidemics have been from cooked meat, fish, poultry, eggs  
and dairy, not raw. Although accepted as absolute truth, there is no  
science that proves the theory that eating a diet which includes raw  
meat/fish/poultry/eggs/dairy would risk infecting the consumer."

The above quotes are from:http://www.bookrags.com/wiki/Raw_food_diet

Which is the best and most comprehensive presentation I've seen of why so  
many have taken to eating raw.
