Aflatoxins（AF）are secondary metabolites produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Under favorable conditions,they can contaminate food and animal feed,posing health risks to both humans and animals. Dairy cows exposed to aflatoxin B₁（AFB₁）excrete its metabolite aflatoxin M₁（AFM₁）into milk,compromising milk safety. This review systematically summarized the effects of AF on dairy cow production performance,rumen fermentation,and reproductive function,and outlines recent advances in the physical,chemical,and biological methods for aflatoxin degradation. The aim is to provide a theoretical basis for preventing and controlling the risks of AF in dairy production.
