How to tell if a onion is good or bad depends on what kind of onion you have. There are several different classifications of onions, and each onion has its own distinctive smell and taste. Some onion varieties are more commonly found than others, while some onion types can only be found in certain locations. Learning how to tell if a onion is poisonous or not has to do with the part of the onion that contains the toxin. Many people don’t realize that a piece of onion is poisonous only if it’s really old; in other words, if it has been around for a few years. Fortunately, in most cases, it is easy to tell when a onion is bad and when it is good.

To test how to tell if a onion is bad or good, you need to look at the skin of the onion. If it has a white, crusty outer layer, then the onion is safe. In order to test how to tell if a onion is good, peel off the white outer layer. If the orange peel is bright orange or bluish-green in color, then the onion is safe to eat. On the other hand, if the peel is yellowish in color or looks like it has greenish veins running through it, then you probably should not eat it. This is because it may contain toxins that will harm or even kill you.

In order to tell if a onion is poisonous, you need to look at the stem of the onion. If it is not prickly, or if there is some divot in the skin that separates the skin cells from the vein, then it is safe to eat. However, if there is no divot, or if the stem of the onion is brittle and damaged, then the onion is toxic. Look carefully at the inside of the onion, where the white pustules called pimples occur.
