Is it still edible on top of moldy rice

It is not recommended to continue consuming the top part of rice after mold has formed under it. Mold growth may produce harmful substances such as aflatoxins, and even if no mold spots are visible to the naked eye, the mycelium may have spread to the entire bag of rice. The common aspergillus in moldy rice can secrete the strong carcinogen aflatoxin, which is resistant to high temperatures and easily spreads through the mycelial network. Experiments have shown that in humid environments, fungal mycelium can penetrate several centimeters below the surface within 3 days. The cooking temperature of home cooking cannot effectively destroy the structure of toxins, and long-term intake may damage liver function and increase the risk of liver cancer. Some people believe that removing moldy parts can ensure safe eating, but there is a risk of misjudgment in reality. In the early stage of mold growth, the mycelium appears transparent and difficult to recognize with the naked eye, and the toxin may have contaminated the rice grains with normal appearance. If it is necessary to consume in special circumstances, it is necessary to ensure that mold growth is limited to the bottom non-contact area and thoroughly washed before high-temperature cooking, but there are still food safety hazards.

Rice should be stored in a cool and dry place for daily use, and sealed containers should be used to isolate moisture. If mold is found, the entire bag should be discarded to avoid sorting and consumption. Rice can be regularly spread out and dried, or placed in food grade desiccants to prevent moisture. If you experience symptoms such as abdominal pain and vomiting after ingesting moldy rice, you should seek medical attention immediately for a liver function test.
