Hygienic quality, study of enterobacteria isolated from table olives and antimicrobial activity of Olea europaea L from Tetouan, Morocco

88 samples of traditional and industrial table olives were collected from various outlets in the city of Tetouan. The physical-chemical controls concerned: pH , ORP (oxydo-reducing potential) and TDE (total dry extract). The microbiological side are: total aerobic mesophilic flora ( TAMB), total col...

This shows that good hygiene practices are not respected. As for industrial olives, the averages in TAMB and SA are below the thresholds set by the standards, and only 19.8% are contaminated with TC which indicates the compliance of the majority of industrial type. Black table olives are the most contaminated.
