Traceability of foods is mainly done at the administrative level, and the use of analytical tools is rare.
Previous studies have demonstrated that microbial ecology analyses at the molecular level (such as PCRDGGE)
could be used to provide food with a unique biological signature that could be linked to the
geographical origin of food. The present study aimed at testing this approach to differentiate farming
types by analyzing organic and conventional food products. To this end, the microbial ecology of organic
and conventional nectarines was analyzed and statistically compared
