“…The genus Salmonella which is classified into two species, Salmonella enterica (type species) and Salmonella bongori based on differences in their 16S rRNA sequence analysis, includes more than 2600 different serotypes and most of these serotypes have the ability to adapt within a variety of animal hosts, including humans [1,2] . L. monocytogenes is gram-positive, rod-shaped, beta-hemolytic, motile, facultative intracellular bacteria, capable of surviving under refrigeration conditions, low pH and in high salt concentration [3] .…”

“…The incidence of listeriosis is low worldwide, however, L. monocytogenes can cause severe and lethal infections, ranging from 20% to 30% (septicaemia, encephalitis and meningitis) during vulnerable periods of life (older adults, pregnant women and immunocompromised patients). Chicken products can be contaminated with L. monocytogenes during processing, or cross-contamination during preparation, cooking, and serving food for other foods [3] .…”

Kafkas Univ Vet Fak Derg, 24 (5): 775-779, 2018775-779, . DOI: 10.9775/kvfd.2018 AbstractThis study aimed to investigate the prevalence of Salmonella spp. and Listeria monocytogenes, their antimicrobial resistance profile. L. monocytogenes was not isolated from any of the samples. Salmonella spp. was detected from 32 (8%) out of the 400 collected samples. Antimicrobial resistance was most frequently observed to nalidixic acid (100%), tetracycline (93.75%), erythromycin (90.6%), streptomycin (84.3%), followed by kanamycin (62.5%). Also, 37.5% of Salmonella isolates were phenotypically confirmed as ESBL producers. Multiple drug resistance was defined 93.75% of the isolates. Among the Salmonella isolates, all of them harbouring qnrB and qnrS genes and, 37.5% of them presented blaTEM gene..

“…Ayaz and Erol () identified 4b (51.4%) as the dominant serotype in turkey meat, followed by 1/2a (27%) and 1/2b (21%). In a study conducted in a chicken slaughterhouse in Brazil, serotype distributions were reported to be 1/2a (87%), 1/2c (8%), and 1/2b (5%) (Oliveira et al, ). In other studies conducted in chicken slaughterhouses, Chiarini, Tyler, Farber, Pagotto, and Destro () reported that 72.9% of L. monocytogenes was 1/2a or 3a, and Bouayad, Hamdi, Naim, Leclercq, and Lecuit () reported that 84.6% were serogroup IIa (1/2a or 3a).…”

The present research was carried out to determine the presence of Listeria monocytogenes in the equipment, staff, and products in the chicken shredding facilities operating in Samsun, and to serotype and genotype the isolates by PCR and PFGE analysis, respectively. Of the total of 192 samples tested, 25 were found to be L. monocytogenes positive from which 51 isolates were acquired. In serotyping of the 51 isolates; 47 (92.2%) and four isolates (7.8%) were identified as 1/2a (3a) and 1/2c (3c), respectively. Twenty‐six of the 51 isolates (51%) were resistant to at least one antibiotic, and 13 (25.5%) were resistant to more than one antibiotic. In the PFGE evaluation, at least 80% similarity was taken as a basis, and in the dendrogram, it was determined as a result of restricting with the Apal enzyme that the isolates were distributed to 25 different clusters and 45 subsets, and as a result of restricting with the AscI enzyme, they were distributed to 29 different clusters and 36 subsets. Practical Application Listeria monocytogenes constitutes a major problem for the food industry due to its widespread availability in nature and its role as an environmental contaminant in food processing plants.

“…A s one of the important food-borne infectious agents, Listeria monocytogenes is still a serious concern for public health with its very high mortality rate (Farber and Peterkin, 1991;Oliveira et al 2018). L. monocytogenes is a specific risk for the health of vulnerable people especially elderly people, immunocompromised individuals and pregnant women who show mortality rate up to 20% (CDC, 2016;Rothrock et al, 2019).…”

Listeria monocytogenes is one of the important causes of food-borne infections. This study was conducted to determine the presence of L. monocytogenes and its serotype distribution in a total of 400 packaged chicken meat products (drumstick, breast, wing, and whole chicken) from different national companies. L. monocytogenes contamination was detected in 26.5% (106 in 400) of all samples when the products considered, drumsticks, breasts, wings, and whole chickens showed 47%, 15%, 35, and 9% positivity respectively. Four important serotypes of L. monocytogenes in human listeriosis (1/2a, 1/2b, 1/2c and 4b) were identified, and serotype 1/2a (94.3%) was determined as predominant in packaged chicken meats. The present study revealed that L. monocytogenes 1/2a serotype is prevalent in chicken meats and this may cause public health problems in Turkey. Further studies in poultry meats should be conducted on a large scale such as regional or national big markets to determine the presence of the pathogen and its dominant serotypes.
