Attribution of Listeria monocytogenes human infections to food and animal sources in Northern Italy

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Emergence and global spread ofListeria monocytogenesmain clinical clonal complex

“…While there is no inter-human transmission of listeriosis, it was only in the mid 1980's that the foodborne origin of human listeriosis was formally proven 15 . Since then, Lm-CC1 has been reported in different food matrixes, including dairy products [16][17][18] which can be heavily contaminated 19 and constitute a major source of human listeriosis 20,21 .…”

Assessment of the Prevalence and Drug Susceptibility of Listeria monocytogenes Strains Isolated from Various Types of Meat

“…Maung et al [19] noted that prevalence of L. monocytogenes in chicken depended on the year of samples analyses and was 53% and 24%, in 2012 and 2017, respectively. According to Filipello et al [11] poultry and pork appear to be the second most important source (after dairy products) of human listeriosis cases in Northern Italy. In Gamboa-Marin et al's [29] study, pork meat cuts had high L. monocytogenes prevalence of 33.9%.…”

“…Profile I included 39 (32.5%) strains susceptible to all antibiotics tested. Statistically the highest number (11,29.7%) of all antibiotic-susceptible strains was reported in poultry meat in 2016 (Table 1 and Figure 3). On the other hand, eight L. monocytogenes strains, classified to profile III, showed resistance to all antibiotics used in the research-six were isolated from poultry and beef meat (four and two, respectively) in 2017 and two from poultry meat in 2018.…”

“…On the basis of the results of the Rapid Alert System for Food and Feed (RASFF) investigation, it can be stated that the products of animal origin are mostly linked to L. monocytogenes infections [9]. Raw poultry and meats, processed meat, and RTE meat products can be contaminated with L. monocytogenes in the slaughterhouse or on different processing steps [6,[10][11][12][13]. It is suggested that most of the meat processing plants may be colonized by L. monocytogenes as soon as during initial production cycles as an effect of raw meat contamination or improper hygienic conditions in the food processing environment (FPE) [1,14].…”
