“…Faecal shedding of L. monocytogenes has been found to occur more frequently in animals that are fed with silage compared to other diets (Fenlon et al, 1996). Furthermore, a higher number of listeriosis cases and increased faecal shedding of L. monocytogenes has been observed during the colder months (Nightingale et al, 2005). However, the latter could also be explained by factors other than silage feeding, e.g.…”

Listeria (L.) monocytogenes is widely distributed in the environment, but also has the ability to cause serious invasive disease in ruminants and humans. This review provides an overview of listeriosis in ruminants and discusses our insufficient understanding of reservoirs and possible cycling ofL. monocytogenes between animal and human hosts, food and the environment. It indicates gaps in our knowledge of the role of genetic subtypes in L. monocytogenes ecology and virulence as well as risk factors, in vivo diagnostics and pathogenesis of listeriosis in ruminants. Filling these gaps will contribute to improving the control of L. monocytogenes and enhancing disease prevention. As the prevalence of listeriosis in ruminants in Switzerland is likely to be underestimated, propositions concerning improvement options for surveillance of listeriosis in ruminants are provided.

Objective. To determine the prevalence of L. monocytogenes in pork carcasses, meat cuts, and meat products ("chorizo", sausage and ham). Materials and methods. Stratified sampling was implemented in meat-processed products. We analyzed 566 (37%) carcasses, 472 (31%) meat cuts, and 481, (32%) meat-processed products, distributed as follows: 169 (11%) sausage, 163 (11%) ham, and 149 (10%) "chorizo", for a total of 1519 (100%) samples in a period of 18 months. The samples were processed using the ISO-17604, ISO-11290-1 and the USDA/FSIS (MLG-8.03) methods. Genus and species were confirmed by multiplex-PCR. Results. We obtained isolates of L. monocytogenes from 21 carcasses (10%), 160 (76%) from meat deboning, 10 (5%) from ham, 6 (3%) from "chorizo", and 13 (6%) from sausage. The prevalence found was 3.7% and 33.9% in carcasses and meat deboning respectively. The prevalence in the meat-processed products was 4.03% in "chorizo", 6.13% in ham and 7.69% in sausage. The overall prevalence of L. monocytogenes in the study was 13.82%. Conclusions. We found L. monocytogenes in different products analyzed, with particular interest in ham and sausage since both are consumed without previous heat treatment.

“…A relationship between listeriosis in domestic animals and the feeding of low quality, improperly fermented silages with pH values > 4.0 has been reported [14,15]. L. monocytogenes is carried asymptomatically in silage-fed livestock and is dropped in feces [16]. Shedding of the pathogen by a variety of domestic animals like sheep and cattle has been reported [16][17][18][19][20].…”

“…L. monocytogenes is carried asymptomatically in silage-fed livestock and is dropped in feces [16]. Shedding of the pathogen by a variety of domestic animals like sheep and cattle has been reported [16][17][18][19][20]. A possible route of infection into the human food chain, for instance, is through the ingestion of uncooked food plants grown on soils irrigated with contaminated water or via the consumption of vegetables cultivated on manure treated fields [21][22][23][24].…”

During a 1-year longitudinal study, water, sediment and water plants from two creeks and one pond were sampled monthly and analyzed for the presence of Listeria species. A total of 90 % of 30 sediment samples, 84 % of 31 water plant samples and 67 % of 36 water samples were tested positive. Generally, most probable number counts ranged between 1 and 40 g were detected. Species differentiation based on FT-IR spectroscopy and multiplex PCR of a total of 1220 isolates revealed L. innocua (46 %), L. seeligeri (27 %), L. monocytogenes (25 %) and L. ivanovii (2 %). Titers and species compositions were similar during all seasons. While the species distributions in sediments and associated Ranunculus fluitans plants appeared to be similar in both creeks, RAPD typing did not provide conclusive evidence that the populations of these environments were connected. It is concluded that (i) the fresh-water sediments and water plants are year-round populated by Listeria, (ii) no clear preference for growth in habitats as different as sediments and water plants was found and (iii) the RAPD-based intraspecific biodiversity is high compared to the low population density.Keywords: biodiversity; fresh water; Listeria monocytogenes; Listeria spp.; sediment; water plants.Dedication: This work is dedicated to the memory of Professor Peter Böger. His continuous support and thoughtful guidance over many years encouraged the senior author to aim at an academic career in microbial ecology and evolutionary biology.
