This is the first time I've ever seen this. EVER.
(I'm 60 years old and have been baking since I was young).
The other day I got out my flour because I needed it to dust the board where I was about to put the biscuit mix that I'd just made up.
I opened the flour bin, and it was *crawling*. Thousands of little tiny brown *things* were crawling around in my flour!!
NEVER saw that before. The bin was sealed. The flour brand was a national brand that I've used All My Life!
I've seen bugs in lentils before, but I bought them in a little middle eastern store. This flour was bought at my local grocery store, again, a national chain. Shocked is a vast understatement of what I felt.
It's been awhile since I bought that flour and the bag it was in was long gone, so contacting the manufacturer would have been useless. I just threw it out (down the drain!) and eventually bought more flour. A different brand.
*shudder*
