ABSTRACT
Samples of caprine milk from bulk tanks of 405 farms in central Spain were analyzed for Listeria spp. once per season over a 1-yr period. Listeria monocytogenes and Listeria innocua were detected in 2.56 and 1.73% of the 1445 samples, respectively. Listeria ivanovii (0.21% samples) and Listeria seeligeri (0.07% samples) were rarely isolated. Only 6 milk samples were contaminated by more than one Listeria species. Most farms (92.59%) produced milk that was apparently free from L. monocytogenes throughout the sampling period, and 88.40% produced milk that was apparently free from Listeria spp. Milk contamination by Listeria spp. was seasonal; incidence in autumn (9.33%) and winter (5.14%) samples was higher than incidence in spring (0.85%) and summer (0.85%) samples. Occurrence of Listeria spp. was lower in samples from mountain farms (1.25%) than in samples from plateau farms (7.03%).
