Somehow, I don't think a chocolate bar is the right environment for flys to lay eggs. It just doesn't ring true to me. I hope we get a follow up on this.
That's not true. I remember when I was nine or so, visiting Jamaica, I bought a Cadbury chocolate bar and started to eat it. I noticed the husk of some worm-creature in the bar. I may have eaten more of them, I don't know. But I threw the rest of the bar away. No big deal, except I was denied my quota of chocolate for the day.
Of course that was years ago and who would think of contacting the media and suing.
The worst I ever did was write the Dove soap people and lied that I couldn't find it in my town and I loved their soap and they sent me a whole case.
I hope we do hear the truth too. I don't know if they were truly maggots, but I have seen WORMS in chocolate candy bars, and believe me, it isn't very appetizing to think you might have just eaten one!
Let me assure you that it happens. It happened to me once with a Reese's Peanut Butter Cup.
