The incidence and ecology of Listeria spp. in farmstead cheese processing environments were assessed through environmental sampling conducted in nine different plants over a 10-week period. Environmental samples (n = 705) were examined for the presence of Listeria spp. by using three detection/isolation protocols. The use of dual enrichment methods, which allowed for the recovery of injured Listeria spp. (mUSDA), identified more Listeria species-positive samples with higher sensitivity than the… CONTINUE READING
