The same thing happened to me. My wife wouldn't even taste them they smelled so bad. But I ate several and they tasted fine and the texture was exquisite. But I don't know what caused the smell. I used ziplok bags, and one of the bags did break during cooking, requiring me to pull out the ribs, clean out the water, and repackage. But the smell was in all the ribs, not just those from that bag. The ribs were also from two different sources, so I think I can rule out the quality of the meat. One batch was from the supermarket, the other from Whole Foods. 72 hours at 132. They still smelled after serious searing on the BBQ. I'm stymied.
