An immunochemical method was proposed for simultaneous determination of aflatoxin and ochratoxin A with the use of mixed solutions of the following reagents: standards of both mycotoxins, antiserums against the mycotoxins, and radioligands of 125I-aflatoxin B1 and 125I-ochratoxin A. The result of the analytical procedure is the value of concentration of the aflatoxin + ochratoxin A sum in the sample. The procedure needs half the amount of reagents as separate determination of each of the two mycotoxin, and is far less laborious. The proposed simultaneous immunoanalysis is suitable for large-are inspection of grain and feed safety from the viewpoint of aflatoxin and ochratoxin A levels.
