“…1) The attack of Listeria from intestinal contents to other fish tissues (for example, muscles) especially when the time from fish death till removing viscera is more than a few hours (Ertas and Seker, 2005), 2) Cross contamination (fish manipulation, using contaminated equipments and inappropriate transport) (Gudbjörnsdóttir et al, 2004;Souza et al, 2008).…”

The present study was conducted to determine the prevalence of Listeria spp. in fish obtained from Urmia fish markets. A number of 194 fish comprising Oncorhynchus mykiss (n=42), Sander lucioperca (n=38), Cyprinus carpio (n=30), Hypophthalmiachthys molitrix (n=48), Abramis brama (n=12), Astacus leptodactylus (n=12) and Silurus glanis (n=12) were obtained from different fish markets of Urmia from June 2009 to February 2010. Listeria isolation was performed in two stages including enrichment in cold and selective plating. After colony formation, in order to confirming the genus of the Listeria, a fragment of Prs gene using Listeria genus specific primers was amplified from isolated bacteria using polymerase chain reaction (PCR). Results revealed that Listeria was isolated from 24 fish (12.37%). The highest prevalence of Listeria was observed in both A. brama and A. leptodactylus with 25%, while the lowest prevalence of Listeria was seen in S. lucioperca (9.7%). From the total of 24 Listeria isolates, five isolates (21%) were confirmed to be L. monocytogenes; seven isolates were L. ivonoi (29%) while L. Seeligeri was not isolated from any examined fish. The study showed that L. monocytogenes and other Listeria species are common contaminant of fish obtained from Urmia fish markets, and this may pose serious public health implications.

“…L. monocytogenes has been observed on the fish surface and in the stomach lining, gills, and intestines, but the flesh is usually free of the organism unless it has been contaminated from different sources. In general, there are 2 possible routes for contamination of fish with Listeria : (1) the spread of Listeria from the intestinal contents to other fish tissues (including muscles), especially if the period between death and viscera removal is greater than a few hours; (2) cross‐contamination (due to manipulation of fish using contaminated equipment and to inappropriate transport) (Gudmundsdottir and others ; Souza and others ). Therefore, contaminated raw materials can also affect the final products, especially RTE‐seafood products (Miettinen and Wirtanen ).…”

With the increased demand for lightly preserved and/or ready-to-eat (RTE) food products, the prevalence of the foodborne pathogen Listeria monocytogenes has increased, which is a public health concern. The goal for this review is to discuss the incidence, epidemiological importance, and contamination routes of L. monocytogenes in various aquatic ecosystems, seafood products, and processing environments and to summarize the data obtained since the 1990s. L. monocytogenes primarily enters the food-production chain by cross-contamination in production plants, making this pathogen a major threat to the seafood industry. This pathogen generally contaminates food products at low or moderate levels, but the levels involved in listeriosis outbreaks are significantly higher. The majority of isolates from aquatic products belong to serotype 1/2a, and outbreaks have been linked to highly similar or even indistinguishable strains. Several seafood-processing plants are colonized by specific "in-house" flora containing special DNA subtypes of L. monocytogenes. In such cases, L. monocytogenes populations can persist and/or multiply despite the inherent obstacles to their growth in food preservation and manufacturing operations. Therefore, food-processing facilities must be designed carefully with an emphasis on effective cleaning and disinfecting operations in the production line.
