Thanks to the development of high throughput sequencing technologies, the bacterial communities present in food are now better described. The data recently acquired question some dogmas or uses in the field of food microbiology, but also enable new possibilities. Indeed, some yet unknown or unexpected species may be abundant in foodstuffs. An extensive analysis of the dynamics of these populations during shelf-life has evidenced some co-occurrence or co-exclusion and sometimes questioned the spoiling potential of some species or, on the contrary, revealed an unexpected spoilage capacity for others. Last, high throughput sequencing data have shown the limitations of cultural methods for ensuring safety or for the determination of the use-by-date. This might enable a more controlled and more efficient use of biopreservation through an increased knowledge of bacterial interactions that occur during spoilage and when protective cultures are used, in particular by revisiting the criteria that are commonly used for characterizing food microbiology.
