Query: Grinds well, but leaves terrible gray ooze in your food.

I purchased this product with high hopes of grinding my own organic chicken and grass-fed beef. I have to say that I was pretty impressed on how well the product grinds the meat, but not at all impressed or happy with the gray metal ooze scraps that are intertwined with the meat on the way out of the grinder. I am very disappointed with this product and would not recommend it to anyone. I have returned it and hope to find one with the same outcome without the metal ooze.
