I have been eating this product for over five years every night. Its unusual for it to start smelling like its going bad on the second day when you open it. I contacted the company and they were very good about refunding my money for three four- packs of this cottage cheese. I still believe its a good tasting product. I just dont understand what caused everyone of its four lunchables to turn so quickly. The representative has no idea either other than possibly the transit involved with the delivery company to the store. All was resolved.
