Validation study of a rapid ELISA for detection of aflatoxin in corn

Abstract

Neogen Corp. developed the Veratox anatoxin test kit for the detection of total aflatoxin. The purpose of this study was to validate the method under the requirements of the AOAC Research Institute Performance Tested Methods SM (PTM) program. There are several AOAC Official Methods SMfor total aflatoxin detection in corn (994.08, 990.33, 979.18, 993.17, 990.32, 993.16, 991.31, and 990.74), varying between rapid and analytical-based methods and one rapid method that has been performance tested by the AOAC Research Institute (PTM 030701). However, the widely used reference method is AOAC Official MethodSM 994.08, which is an HPLC method and is referred to as the reference method in this paper. Although considered the reference method, the HPLC procedure is complicated and requires the investment of both expensive equipment and a highly skilled technician. A rapid (e.g., ELISA) test kit to be validated by the AOAC Research Institute is needed.
