The core hazard of aflatoxins in feed lies in their strong toxicity and carcinogenicity. They can be transmitted through the "feed-animal-human" food chain, posing a double threat to animal 

health and human food safety. 

The specific hazards mainly manifest in the following two aspects: 

1. Harm to animals: 

• Damages the liver: It causes liver cell necrosis and fibrosis, leading to hepatitis, liver cirrhosis, and even liver tumors. It is one of the main causes of liver damage in animals. 

• Reducing production efficiency: Suppressing the animal's appetite, reducing nutrient absorption, resulting in a decrease in egg production in poultry, slower growth in livestock, weight loss, 

and a significant reduction in farming profits. 

• Damages the immune system: Inhibits the activity of immune cells, reduces the animal's resistance, making it more susceptible to bacterial, viral and other pathogen infections, and 

increasing the risk of illness. 

• Teratogenicity and mutagenicity: At high doses, it may cause deformities and death in animal embryos. Long-term low-dose exposure may also lead to genetic mutations.

2. Harm to Humans: 

Food chain accumulation: When animals consume feed containing aflatoxins, the toxins will remain in tissues such as the liver, kidneys, muscles, eggs, and milk. Humans who consume these 

contaminated animal products will indirectly ingest the toxins, thereby posing health risks. 

• Highly carcinogenic: Aflatoxin is recognized as a type 1 carcinogen. Long-term low-dose intake can significantly increase the probability of human liver cancer, and may also be associated 

with other cancers such as stomach cancer and kidney cancer. 

• Risk of acute poisoning: Consuming a large amount of contaminated animal products within a short period of time may lead to acute poisoning, presenting symptoms such as nausea, 

vomiting, jaundice, liver failure, and in severe cases, it can even be life-threatening.
