Hello, I'm a food safety expert with extensive knowledge on the preservation of various food items, including dairy products like yogurt.

Once opened, yogurt can typically last for about 1 to 2 weeks in the refrigerator. However, it's important to store it properly to maintain its quality and safety. After opening, you should:


1. Seal the container tightly to prevent the entry of bacteria and other contaminants.
2. **Keep it in the coldest part of the fridge**, ideally at a temperature below 40°F (4°C).
3. **Consume it within the use-by or best-before date**, which can be found on the packaging.

Remember, even if it's within the time frame, you should always check for signs of spoilage before consuming. If the yogurt has an off smell, excessive mold, or a watery texture, it's best to discard it.
