title: Incidence of Listeria spp. in Dairy Cows Feed and Raw Milk in Latvia.
abstract: Feed is a risk factor for poisoning the farm environment thus also fresh milk with pathogenic microorganisms of Listeria genus species. Listeria ivanovii, Listeria innocua, and Listeria seeligeri were isolated from 9.2%, but Listeria monocytogenes from 20.0% of feed samples. Most often different fodders (9.3%) and silage (4.7%) were contaminated with Listeria monocytogenes. Listeria genus species were isolated more often from feed prepared and used in organic dairy farm than from that used in conventional dairy farm, correspondingly 44.4% and 18.3%. No Listeria monocytogenes was found in bulk milk samples of organic dairy farm.
