Vegetables that should be avoided even if given for free:
Overgrown bean sprouts: Bean sprouts are nutritious, but if they are not grown properly, they can be contaminated with toxins. Therefore, it is advisable to avoid buying bean sprouts without roots as they may be contaminated with chemicals, increasing the risk of serious cancer and posing a serious danger to consumers. Some sellers even refuse to eat them.
Withered or partially moldy vegetables: Fungi mold on vegetables produce toxins, especially dangerous aflatoxins, which can damage liver cells, cause degeneration and necrosis, and lead to liver cancer.

Aflatoxins, the toxins produced by moldy vegetables, are very dangerous and can directly harm liver cells. Rotten or sprouted ginger.
Sprouted or moldy ginger: Ginger is a spice that is good for health, but when it sprouts or develops mold, it produces safrole, a highly toxic substance that can cause degeneration of liver cells and, over time, liver and esophageal cancer. Even if you cut off the moldy part, the rest is still not safe to consume. Therefore, it is absolutely necessary to avoid this type of ginger.

Eating a large amount of these sweet potatoes can cause acute poisoning, with symptoms such as difficulty breathing, nausea, and diarrhea. In the long run, it can lead to the accumulation of toxic mold substances, which can be harmful to internal organs. Moreover, the black rot bacteria can secrete a toxin called seton on sweet potatoes. Consuming a significant amount of seton from sweet potatoes can lead to severe poisoning, with symptoms such as high fever, seizures, vomiting blood, coma, and even death.
