If I find bloody chicken in a bag of frozen chicken that is supposed to be fully cooked, do I have a case against this very large meat company?

I would think that if your cooking it did not cause the blood to disappear, then the company's pre-cooking would not be expected to remove it either. I assume you did cook the piece that had the blood on it. You should call you Dr. if you have one or see if the internet has any information on how long it takes to get sick from uncooked chicken, but I would expect you and your dogs would be sick by now if there was some bacterial infection. I do not handle this type of case, so I do not know if this is the type of problem you could reasonably expect to occur, but even if the Company is liable, what are your damages? Mere emotional distress normally is insufficient to claim damages for.
