Once you open a carton of orange juice, you'll only have around seven to 10 days to enjoy it. It is always important to check your carton for a "use by" date prior to opening it.

There are a few signs to look out for to see if it's spoiled. If the carton feels bloated or swelled, it may be best to toss it.

The smell of the OJ is also a pretty good indicator that it's past its prime. Any rotten or vinegar-like scents are a good gauge for knowing that the juice is spoiled.

Orange juice should still be vibrant and brightly colored. If any mold or lumps are present in the liquid, it's absolutely a no-go.

Although it may be tempting to hold onto a half-full carton of juice, it's better to err on the side of caution if any spoilage is spotted.
