No, it's because of salmonella. In chickens infected with salmonella, unlike other animals, the salmonella is present in the flesh itself. And it's pretty common for chickens to be infected.
May well be it. I personally hate the consistency of raw chicken. Maybe instinctively we evolved to hate it because of salmonella. Raw fish? No problem, raw beef? Yummy. But I cannot swallow raw chicken and I generally ask my money back wherever they serve me that thing (it's happened a couple of times!)
