Half and half in your coffee that curdles into floating chunks is not always spoiled. Very hot or very acidic coffee can curdle fresh half and half. But if the carton smells sour before you pour, that is genuine spoilage.
How to Store Half and Half
Keep refrigerated at all times. Use within 5-7 days of opening. Individual creamers (shelf-stable) can be stored in the pantry until opened. The carton date is a guide; trust your nose and taste.

The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.
The Bottom Line
Properly stored half and half stays safe for 5–7 days in the fridge. Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been.
