What's With This Charred Piece Of Jack 'n Jill Nova?

While enjoying the taste of 
Jack 'n Jill Nova, 
I noticed something that was not like
the rest of the pieces - 
one piece was completely charred! 

When I saw that charred piece 
of Jack 'n Jill Nova, 
I took a pic and video right away. 
Then I got worried 
because it might be harmful or dangerous. 
And I wasn't sure if 
it was the only one charred 
or if I've already eaten the other/s. 
The big question is, 
is it edible like the rest of the pieces? 
And if not, 
is it harmful or dangerous? 
And if so, 
did it contaminate the other pieces 
since they were in the same pack? 

I was thinking this was 
some manufacturing defect or fail 
and I know it happens once in a while 
even in some well-known, established companies. 
But my concern and worry is, 
I've already munched on several pieces 
before I noticed the charred one. 
I hope this gets to the company 
manufacturing Jack 'n Jill Nova. 
I will always love Nova no matter what.
