I purchased a large box of Clover Valley Bite Size Frosted Mini Wheats Cereal on Feb. 21, 2011 at Store 00366. On February 23, 2011 around 6:30 am, I poured my 1st bowl of cereal from that box. As I was about to take my 1st bite, I noticed something green swimming around in my spoon, just before it entered my mouth. I looked through the bowl of freshly poured cereal and noticed a lot of sharp, green, plastic shavings floating in my bowl. I trashed the uneaten cereal and am returning the box of cereal to the retailer today. I hope noone has eaten those particles from other prepackaged cereal productes. I am glad that I was the first one to attempt to eat from that box instead of my small children. I am thoroughly disgusted by this experience and do not plan to purchase food products from Clover Valley in the future. I will do my grocery shopping from a grocery store from now on. Fuel prices are outrageous and my time is valuable. Therefore, I do NOT like to make extra trips to make returns. I plan to contact the FDA regarding my experience so they can monitor this situation.
