The attached picture is from a hazelnut I shelled just a bit ago. IT WAS FULL OF MOLD!
I was sitting there, thinking how odd that some of you suggest cracking open even store-bought nuts to check for mold. I've given Muggsy nuts several times that were unopened. I'm an idiot!
Something told me to crack open a couple of nuts. I wasn't giving any to Muggsy anyway, as he was already in bed for the night...but I just had to open a couple.
BAM!
This is TERRIFYING. This was from a bag of unshelled, fresh(?), mixed nuts.
Wanted to share.
