Hello, I'm a food safety expert with extensive knowledge on how to identify spoiled food products, including yogurt. When it comes to yogurt, there are several signs that can indicate whether it has gone bad. Here's what you need to look for:


1. Expiration Date: Always check the expiration date on the packaging. Yogurt is generally safe until this date, provided it has been stored properly.

2. Mold: If you see any mold, even if it's a small spot, discard the yogurt. Mold can be harmful if consumed.

3. Odor: A sour or off smell is a clear sign that your yogurt has spoiled.

4. Texture: Yogurt should be smooth and creamy. If it's lumpy, watery, or separated, it might be a sign that it's no longer good.

5. Color: Yogurt is typically white or off-white. Any unusual discoloration, like a yellow or green tinge, could indicate spoilage.

Remember, when in doubt, it's best to throw it out. Consuming spoiled yogurt can lead to food poisoning.
