“…When comparing the amount of exopolysaccharides that was produced by the cells of biofilm formation on different types of pipes in both TEM and determination of EPS results, it is clear that, L. monocytogenes biofilm grown on copper pipe (203.7 g/cm 2 ) produced lower amount of exopolysaccharides than the others types of pipes Fig. (1-E).…”

This work aimed to determine the influence of different chlorine doses to inactivate of Listeria monocytogenes biofilm cells collected from six types of pipe materials, which are commonly used in household at different biofilm ages. A laboratory-scale simulated distribution system, that consists of a design based on six different pipe materials which are: polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), iron (I), copper (Cu) and rubber (R). Six samples of L. monocytogenes biofilm were collected from the previous designed system at three different biofilm ages (10, 40 and 90 days-old). The collected biofilm samples were exposed to different chlorine doses (0.2, 0.6, 1.0, 1.4, 1.8, 2.2, 2.6 and 3.0 mg/l) at 10 min, and then total bacterial counts using pour plate method was enumerated. The results showed that the log reduction of 90 days-old of L. monocytogenes biofilm formation, when exposed to 3.0 mg/l of chlorine dose, on six pipe materials; PVC, PP, PE, I, Cu and R was 3. 96, 4.16, 4.21, 4.17, 4.32 and 4.03 CFU/cm 2 , respectively with the initial count of biofilm cells was 10 6 CFU/cm 2 . While the log reductions of L. monocytogenes planktonic cells were: 6.20 CFU/ml (complete reduction) at the same dose of chlorine dose. The present study concluded that the biofilm cells are more resistant to chlorine dose than planktonic cells. Moreover, the biofilm of 10 days-old is more sensitive than 40 days-old followed by 90 days-old that grows in different pipe materials. In addition, chlorine effectiveness depends on its concentration, the exposure time, nature of pipe materials and the age of biofilm.

“…In a study on blue crab, C. sapidus, 19.5% of raw crabs collected in US were positive for presumptive Listeria spp. and 4.5% were confirmed to be Listeria monocytogenes [36]. Clostridium botulinum, another food-borne, toxigenic pathogen of concern, can be present in fresh crab meat of blue crabs [37].…”

Listeria can be found in fish, molluscs and crustaceans, whether fresh or frozen, raw or undercooked fish products (Embarek 1994;Jørgensen and Huss 1998;Destro 2000;Pagadala et al 2012). The contamination routes of Listeria in processing plants include surfaces (skin, mucus, tail and head) and the intestinal cavity of the fish.…”

L. monocytogenes is the bacterium that causes an infection known as listeriosis. Although rare, the disease has an important impact, with a mortality rate of 20-30 % among groups such as immunocompromised individuals, the elderly, infants and pregnant women. Contaminated seafood products are among the foods that cause the transmission of listeriosis, which occurs primarily by consuming infected food. Refrigerated ready-to-eat fish products such as smoked salmon and semi-preserved fish, in particular, are the foods in which L. monocytogenes is most commonly found.
