If you did not eat and/or sustain injury from the product, it is unlikely that there will much recovery. The manufacturer is entitled to proof that there was actually a foreign substance in their product. A picture alone will probably not suffice. You should contact the local grocery store where you purchased the product to them know about the condition of the product.
I agree with Mr. Rosenstein that were you to sue, there would not be much in damages. As disgusting as finding what you did obviously is, the case is small claims. I would send it to them via the grocer who might give you a refund.
