Imagine you cut open a cucumber only to find small holes inside. You may wonder if it’s safe to eat it. Usually, there’s no problem with still eating it. Cucumbers are actually made up of three separate segments, and sometimes they don’t fully connect inside leaving up to three lengthwise holes. These are natural phenomena and don’t affect the cucumber or the taste. If the holes are irregularly shaped and wiggle all around, then you may have a pickle worm inside. If you see this, or you find a worm inside your cucumber, just toss it.
