if someone has been diagnosed with a known disease, and then dies of it, then no, an autopsy usually is not performed. And who is really going to question a doctors diagnosis and push for an autopsy of their loved ones. And some cases do occur, under a 100 or so a year in this country, that are just declared naturally occuring. I am pleased we don't have an epidemic in this country, but I am not convinced that while England had 100's of cases of this disease we've had none, in a time when the govt has been gutting all oversight of the meat industry.
there doesn't have to be a grand conspiricy for things to be underreported. My mom was greivously injured by statin drugs, went to her doctor probably 2 dozen times and always said it can't be the statins, I have never seen this, it just can't be the statins. She finally just stopped taking them (against her doctors advice while he was going to have her do another round of tests that was finding nothing) and her symtpoms were gone in less than a week. And this doctor still doesn't believe it was the statins, and anyone else that comes in with the same symptoms he is going to tell the same thing. Its not like my mom reported it anywhere else, there is no real database of this stuff. Multiply that by a thousands of doctors, or an industry that relies on public confidence (like the meat industry) and you can have quiet injuries going on with no conspiricy other than a collective head in the sand.
