The invention relates to a double-antibody sandwich method for detecting enterobacter sakazakii in food. The method is characterized in that the enterobacter sakazakii (ATCC29544) and lipopolysaccharide (LPS) extracted by coupling the enterobacter sakazakii (ATCC29544) with BSA (bovine serum albumin) are respectively used as immunogen to simultaneously immunize BALB/c mice, and 11 enterobacter sakazakii monoclonal antibodies are obtained through immunization, fusion and screening to respectively label HRP (horse radish peroxidase) and are paired through the enterobacter sakazakii. A No.7 monoclonal antibody CGMCC No. 7207 is used as a coating antibody, a No.8 monoclonal antibody CGMCCNO.7208 is used as an enzyme labeled antibody, a sandwich ELISA method of the enterobacter sakazakii is established by adopting the ATCC29544 as a standard product, and LOD is 53000CFU/Ml. By adopting the monoclonal antibody with high physicochemical property, good uniformity, good specificity and capability of being in mass preparation, the established sandwich method is high in sensitivity and low in cost, no cross reaction with salmonella enteritidis, E.coli, E.coliO157: H7, salmonella typhimurium, staphylococcus aureus and listeria monocytogenes exists, and thus a rapid and high efficient analysis means is provided for detecting the enterobacter sakazakii in the food.
