well, here resto and kfc seem to emphasize that they cook chicken at 350 deg C (or some high number like that), ensuring 'avian flu free'
i don't have direct experience with avian flu (I was in Taiwan during SARS, wearing masks, but didn't catch the flu) so i assume i can get it from eating ... well maybe it's just a marketing tactic from kfc and others
but still the peace of mind is there :D not having to worry about some stuffs is great
