“…Moreover, factors related to milking hygiene conditions in dairy farms were significantly associated with the contamination of raw milk with L. monocytogenes (Sanaa et al, 1993). In Brazil, previous studies have reported the incidence of L. monocytogenes in milk and dairy products (Destro et al, 1991;Casarotti et al, 1994;Moura et al, 1993;Silva et al, 2003;Nero, 2005;Arcuri et al, 2006;Barancelli et al, 2014).
