Is it safe to eat purple sweet potatoes after they have rotted?

Generally speaking, it is not recommended to eat spoiled purple sweet potatoes. The detailed explanation is as follows:

Purple sweet potatoes usually rot due to prolonged storage or improper storage conditions, such as a humid or high-temperature environment. Under unfavorable conditions, microorganisms on the surface of the purple sweet potatoes, such as bacteria and mold, begin to multiply rapidly. The nutrients are decomposed and damaged by these microorganisms, resulting in reduced nutritional value. At the same time, spoiled purple sweet potatoes may produce various toxins harmful to human health, and long-term ingestion may pose a threat to health. Therefore, it is generally not recommended to eat spoiled purple sweet potatoes.

It is recommended to purchase fresh and intact purple sweet potatoes and store them in a dry, well-ventilated place. Additionally, regularly inspect stored purple sweet potatoes, and immediately isolate and dispose of any that show signs of spoilage to prevent cross-contamination.

In daily diets, it is recommended to consume appropriate amounts of food based on personal taste and needs, and to maintain a balanced diet to meet individual nutritional requirements.
