How to Tell If Your Milk Has Gone Bad

Although checking the expiration date is helpful, the best way to tell if your milk has gone bad is to rely on your senses. Spoiled milk usually gives off a strong sour smell that’s noticeably different from fresh milk’s mild scent.
Look for visible signs like curdling, lumps, or a yellowish tint—these indicate bacterial overgrowth. When you taste a small amount, an off-taste confirms spoilage.
Texture changes such as thickening or sliminess also signal that the milk isn’t safe to consume. These sensory cues are more reliable than the expiration date, which only offers a general guideline.
