How long does it take for a bag of moldy rice to become cancerous

Eating moldy rice does not directly lead to cancer, but long-term intake may increase the risk of cancer such as liver cancer. Moldy rice may contain carcinogens such as aflatoxins, and the main hazards include toxin types, intake doses, individual metabolic differences, basic liver function, and nutritional status. The aflatoxin in moldy rice belongs to the first level carcinogens and has strong toxicity to the liver. Short term ingestion of small amounts may only cause symptoms of acute gastroenteritis, manifested as nausea, vomiting, or diarrhea. Continuous low-dose exposure can lead to chronic damage to liver cells, which may result in non-specific symptoms such as fatigue and decreased appetite. Long term repeated intake significantly increases the probability of liver fibrosis, cirrhosis, and even hepatocellular carcinoma. The carcinogenic effect of aflatoxin is closely related to cumulative exposure. Adults consuming more than 1 milligrams per day may cause acute poisoning, while long-term daily intake of more than 20 micrograms poses a risk of cancer. Children, pregnant women, liver disease patients and other groups are more sensitive to toxins. The more severe the mold, the more humid the storage environment, and the higher the frequency of consumption, the greater the accumulation of toxins. People who lack high-quality protein and B vitamins at the same time have decreased liver detoxification ability and are more susceptible to toxin invasion.

If you accidentally consume moldy rice, you should immediately stop eating it and drink more water to promote metabolism. Daily storage of rice should be kept dry and ventilated, avoiding high temperature and high humidity environments. It is recommended to regularly check the condition of the grain. If clumping, discoloration, or odor occurs, the entire batch should be discarded. Adding dark vegetables, green tea, and other foods rich in antioxidants to the diet can help reduce toxin damage. If there is long-term exposure to moldy food or persistent symptoms such as abdominal pain and skin yellowing, it is necessary to seek medical attention promptly for liver function screening.
