Tag: Spoiled sweet potato

While the edible tuber of the common sweet potato is not inherently poisonous, there are specific circumstances under which it can become harmful. The primary threat comes not from the vegetable itself, but from a mold that produces a toxin called ipomeanol, typically following physical damage or improper storage. Understanding how to identify spoilage is key to preventing health risks and enjoying this nutritious vegetable safely.

According to the U.S. Department of Agriculture, while sweet potatoes are generally very safe, certain signs can indicate spoilage that can lead to illness, making it crucial to know how do you know if a sweet potato is poisonous. Most risks are related to general rot or mold, not inherent toxicity like with green regular potatoes. The primary indicators involve visible mold, off-putting odors, and a change in texture, which can all signal that the root is no longer safe to eat.
