Which method? A food microbiologist's nightmare

A common dilemma faced by Australian food testing laboratories is the selec tion of the most appropriate microbiological method to meet specific testin g requirements. Frequently food microbiologists seek guidance from NATA, or refer to methods published by Standards Australia. However this often lead s to criticism of either or both organisations because of apparent constrai nts imposed by regulatory requirements, and an inherent inability of Austra lian Standard Methods to keep pace with scientific and technological develo pments, and with innovations in test methods. One potential solution which has been the subject of prolonged debate within and between NATA and Standa rds Australia, is the development of recognised procedures for the validati on of test methods. This paper describes the processes involved in developing Australian Standa rd Methods for food microbiology, examines misconceptions and myths surroun ding their use, explores some solutions which have been developed, and high lights challenges for the future.
