Fresh tomato juice is delicious to drink or can for later use in your favorite recipes. But you need to know that your juice is fresh, not spoiled. Often, the tomatoes used to make the juice are the reason your juice will spoil. Tomatoes that are moldy, slimy, or have dark spots on them will spoil faster when used to make tomato juice. Bad tomatoes can cause bacterial sickness, diarrhea, and vomiting. Symptoms can develop within 17 to 24 hours after drinking or eating spoiled tomato juice. As with all fresh foods, there are various signs to watch out for that will let you tell your tomato juice is spoiled.

How To Tell If Tomato Juice Is Spoiled

Search for dark or black areas on the surface of the tomato juice. If the dark areas have a fuzzy texture to them, it means they're moldy.

Look for a slimy clear or cloudy substance in the juice. This can be seen on the surface or throughout the juice.

Tomato juice may separate in the container. The tomato puree will sink to the bottom and the water will float to the top. This is normal for fresh tomato juice but if the tomato puree is unusually thick, the juice is bad.

Smell the tomato juice. If the tomato juice has a putrid smell, it is spoiled. If the smell is unusual, it is likely that the tomato juice is spoiled.


Do not drink or taste tomato juice if you believe it may be spoiled. Call your doctor or 911 if you experience vomiting or diarrhea after drinking tomato juice.
