Smell Can Be Deceiving: How to Know If Milk Has Spoiled
We've all been there – standing in front of an open refrigerator, holding a carton, and carefully checking the milk. Sometimes it's immediately clear it has spoiled due to a strong unpleasant odor, but sometimes the signs are not so obvious. Although typical indicators of spoilage are a sour smell, yellowish color, and lumps, surprisingly, an unusual smell doesn't always have to come from the milk itself, according to Allrecipes.

TL;DR
- Signs of spoiled milk include a sharp, sour smell, lumpy or slimy texture, and a yellowish or off-white color.
- An unusual smell may come from dried residue on the carton or other fridge odors, not the milk itself.
- Pour milk into a clean glass to properly assess its smell.
- Store milk in the back of the refrigerator, not the door, for a stable temperature.
- Keep the carton tightly closed and avoid drinking directly from it.
- Ensure the refrigerator temperature is set to 4 degrees Celsius or lower.
