The analytical data of 18 samples of industrial ice cream obtained by three different methods were compared: a) MPN in Brillant Green Bile Lactose Broth, b) plate count in Violet Red Bile Lactose Agar, c) plate count in VRBLA after a resuscitation step of the homogenate in Triptic Soy Yeast Broth at 25 degrees C for 2 hours to recover injured cells. The results show that the first and the second procedures allowed a similar recovery, and the third permitted a significative increase in coliform concentrations as consequence of the revivification of the damaged cells.
