Abstract: Mycotoxins are metabolites produced by the growth of fungi in food or feed,these low molecular weight compounds are naturally occurring and also unavoidable.Fungi enter the food chain through two ways:On the one hand,they can enter the food chain directly from plant food components contaminated with mycotoxins;On the other hand,they can enter the food chain through indirect contamination of the growth of poisonous fungi in food.Mycotoxins are widely found in mature corn,grains,soybeans,sorghum,peanuts and forage crops.Eating foods or feeds contaminated with mycotoxins can cause acute or chronic toxicity to humans and animals.In addition to the adverse effects of direct consumption of food and feed contaminated by mycotoxins,mycotoxins also have public health problems caused by intake of animal-derived foods,such as meat,milk or eggs,residues or metabolites containing mycotoxins.Although more than 400 mycotoxins have been identified,6 toxins are widely found in food:Aflatoxin,ochratoxin,zearalenone,fumonisin,vomiting toxin and T-2 toxin,which have caused persistent food safety problems around the world.This review summarizes the toxicity of 6 mycotoxins,focusing on the recent advances in the detection of these biomyxins by electrochemical biosensors,aiming to prospectively develop their prospects for mycotoxin detection through a series of summaries.

Key words: electrochemical immunosensor; electrochemical aptamer sensor; electrochemical enzyme sensor; mycotoxins
