“…Moreover, the presence of L. monocytogenes in food has important economic consequences, such as the withdrawal of products from the consumer marketplace and a decrease in sales of the incriminated products [ 112 ]. Due to ubiquitous nature of Listeria species and their unique ability to survive across a broad range of environmental stress including pH, temperature, and salt, they are considered as important food-borne pathogens [ 113 ].…”

Food-borne microorganisms are major pathogens affecting food safety and cause human illness worldwide as a result of consumption of foodstuff, mainly animal products contaminated with vegetative pathogens or their toxins. Most of these microbes have zoonotic importance resulting in significant impact on both public health and economic sectors. Bacteria are the causative agents of two-thirds of human food-borne diseases worldwide with high burden in developing countries. Hence, the objectives of this review paper are to highlight the background of food-borne bacterial pathogens and to review common major food-borne zoonotic bacterial pathogens. Food animals are the major reservoirs of many food-borne zoonotic bacterial pathogens, and food products of animal origin are the main vehicles of transmission. Meat, dairy products, and eggs are the main ways by which people are exposed to zoonotic bacteria. S. aureus, Salmonella species, Campylobacter species, L. monocytogenes, and E. coli are the major zoonotic bacterial pathogens which are the causative agents of food-borne illness and death in the world associated with consumption of contaminated animal products. Production of toxins and structural virulent factors are responsible for the pathogenesis of these bacteria. These major zoonotic bacteria cause human infections which are characterized mainly by gastrointestinal symptoms including nausea, vomiting, diarrhea, abdominal cramps, and other agent-specific symptoms. Some bacteria may cause severe complications. Conventional (culturing), serological, and molecular techniques are important for detection of these common zoonotic bacteria and their toxins in food. Good hygiene, GMP, sanitation in operating procedures, and implementation of standardized HACCP and pasteurization procedures are effective methods for the control and prevention. Currently, the emergence of multidrug-resistant zoonotic bacteria associated with consumption of contaminated animal products is a great concern for the public health, and there should be coordinated surveillance and monitoring system for food-borne zoonotic bacterial pathogens particularly in developing countries including Ethiopia.

“…Among them, L. monocytogenes and L. ivanovii are human and animal pathogens ( Snapir et al, 2006 ; Jagadeesan et al, 2019 ; Lee et al, 2020 ). These bacteria can cause severe listeriosis, leading to spontaneous abortion, neonatal sepsis, and meningoencephalitis, and the post-infection mortality rate ranges from 20 to 30% ( Radoshevich and Cossart, 2018 ; Ranjbar and Halaji, 2018 ), which places this pathogen among the most frequent causes of death from foodborne illnesses ( Tamburro et al, 2015b ).…”

Listeria spp. is an important foodborne disease agent, often found in the fresh mushroom (Flammulina velutipes) and its production environment. The aim of this study was to develop multiplex PCR for rapid identification of Listeria monocytogenes and Listeria ivanovii, and nonpathogenic Listeria in F. velutipes plants. Pan-genome analysis was first used to identify five novel Listeria-specific targets: one for the Listeria genus, one for L. monocytogenes, and three for L. ivanovii. Primers for the novel targets were highly specific in individual reactions. The detection limits were 103–104 CFU/mL, meeting the requirements of molecular detection. A mPCR assay for the identification of pathogenic Listeria, with primers targeting the novel genes specific for Listeria genus (LMOSLCC2755_0944), L. monocytogenes (LMOSLCC2755_0090), and L. ivanovii (queT_1) was then designed. The assay specificity was robustly verified by analyzing nonpathogenic Listeria and non-Listeria spp. strains. The determined detection limits were 2.0 × 103 CFU/mL for L. monocytogenes and 3.4 × 103 CFU/mL for L. ivanovii, for pure culture analysis. Further, the assay detected 7.6 × 104 to 7.6 × 100 CFU/10 g of pathogenic Listeria spiked into F. velutipes samples following 4–12 h enrichment. The assay feasibility was evaluated by comparing with a traditional culture-based method, by analyzing 129 samples collected from different F. velutipes plants. The prevalence of Listeria spp. and L. monocytogenes was 58.1% and 41.1%, respectively. The calculated κ factors for Listeria spp., L. monocytogenes, and L. ivanovii were 0.97, 0.97, and 1, respectively. The results of the novel mPCR assay were highly consistent with those of the culture-based method. The new assay thus will allow rapid, specific, and accurate detection and monitoring of pathogenic Listeria in food and its production environment.

“…According to a meta-analysis review from Iran by Ranjbar and Halaji (2008), the prevalence of L. monocytogenes from human origin was higher (10%) compared with animal and food resources (7% and 4% respectively). However, international comparison on the prevalence of L. monocytogenes is difficult due to multifactorial nature of L. monocytogenes (Ranjbar and Halaji, 2018).…”

The ubiquitous of Listeria monocytogenes in the environment and in the niche of foods can be related with the ability of the pathogen to survive in adverse conditions, in example, low temperature and pH, high concentrations of salt and bile, oxidative stress and carbon starvation. Besides, most of the human listeriosis are food-borne and L. monocytogenes consists of a spectrum of strains with varying virulence and pathogenicity. Moreover, the virulent regulators play a role in facilitating better adaption or persistence of L. monocytogenes in the food environment. This review included prevalence, pathogenicity, survivability and antibiotic resistance of L. monocytogenes in various categories of foods such as meat, seafood, dairy products and vegetables. The recent updates on listeriosis or foodborne cases associated with L. monocytogenes should be studied in order to have a better understanding of their persistence in the food chain and its public health impact especially among the high-risk groups: elderly, infant, pregnant woman and immunocompromised individuals.
