I opened a 4 pack of pumpkin greek yogurt and saw it had expired on the 3rd of September. Despite it still being summer. The first one I had smelled and tasted fine. I opened 2 more and they smelled funky. My mom said it was just cinnamon but I didn't trust them. Hopefully the one I ate contiunes to be ok on my stomach. If I wasn't a pumpkin fanatic I would have thrown them all out.
