Abstract: Disclosed is a method for producing anti-E. coli O157 antibodies. Anti-E. coli O157:H7 antibodies are produced in egg-laying hens and isolated from the eggs. E. coli O157:H7 is cultured in a brain heart infusion broth and killed by the treatment with hot water for 5-10 min. After being collected by centrifugation, the dead bacteria is homogenized. Serving as an antigenic material, the bacterial homogenate is injected into egg-laying hens to induce antibodies against E. coli O157:H7 in the eggs. The induced antibodies are isolated from the yolk of the eggs and the eggs containing the antibodies against E. coli O157:H7 can be utilized, in their entirety, for foods. Alternatively, the yolks are separated from the eggs and freeze-dried. The resulting dried egg component can be applied to processed foodstuffs, alone or in combination with whole eggs. Since the antibodies against E. coli O157:H7 are contained in frozen eggs, it is very convenient to store the antibodies.
