title: Update on validation of microbiological methods by AOAC International.
abstract: An update is presented of the microbiological methods validated by AOAC since 1983. A sequential listing of the microbiological methods adopted first action between 1939 and 1993 gives the permanent new numbers of each, as introduced in Official Methods of Analysis, 15th Edition. Consideration is given to the expanded applicability of approved methods with respect to food matrix; the predominance of methods for the detection, identification, and serological testing of Salmonella spp.; and the procedures for coliforms and Escherichia coli, which were most frequently approved between 1973 and 1993. The substantial increase in validation of test kits is discussed, and categories of methods for the modification of test kits already approved are defined.
