Abstract: As broad-spectrum semi-synthetic antibiotics with strong antibacterial effect and little toxic side effects, cephalosporins are widely used in livestock and poultry farming, and the food safety risk arising from this is becoming the focus of public attention. At present many governments and food safety agencies have set maximum residue limits for cephalosporin residues in milk. This paper interprets the potential health risk of cephalosporin residues in milk, and summarizes recent progress in the development of pretreatment methods and detection technologies for cephalosporin residues in milk in detail.

Key words: cephalosporins; antibiotics; milk; pretreatment methods; detection technologies
