Also like the bsc thing with beef.
Have you noticed though when these 'scares' crop up how we're always told not to worry too much because the risk is only very small etc etc. Maybe it is, but the powers the be are never going to abmit to something that will cause everyone to panic big time even if what has occurred was highly dangerous to everyone. I doubt we are ever told the whole truth about these things.
And as others have said, if you've already eaten it, then it's too late anyway
