Abstract: Gene chip technology has provided a new tool and platform for rapid detection of various microbes in multipleenvironments as water,air,soil and food. It was briefly reviewed about recent progresses on testing of food microbes by genechip based procedures. The discussions were focused on the basic principles and steps of testing of food microbes by genechips,collection and preparation of food samples,the methods and requirements for separating and purifying food microbialDNA,detecting and studying of common pathological bacteria in food with gene chip based technology,and the currentstatus and perspectives on the applications of gene chip on food microbiology assay.

Key words: gene chip, food microbe, detection
