The Crayfish are the largest freshwater crustacean via high skill opposite wide range of environment variables and The freshwater Crayfish Astacus leptodactylus (A. leptodactylus) is the one of the important species of Crayfish family that rearing it significant in several nations . Iran has a significant role in export of A. leptodactylus to European nations. A number of species have been used aquaria and some use seafood consumer. Listeriosis have become an important topic in biomedical research because of its central role in food microbiology and medical microbiology. In Iran, some reports is available on prevalence of Listeria spp. in A. leptodactylus. The aim of this study was to find the prevalence of Listeria monocytogenes in A. leptodactylus meat samples in Iran. From November 2012 to February 2013, a total of 40 meat samples of A. leptodactylus samples were obtained from randomly selected localities in “Aras Dam” , Western-Azerbaijan Province , Iran. The samples were tested for the presence of L. monocytogenes using Polymerase Chain Reaction (PCR). Three samples (7.5%) were positive for L. monocytogenes by PCR method. The results show that crayfish from the studied area regularly contain this pathogen that is important to public health. Consumption of these sea foods, either raw or undercooked, may give to food borne illness in Iran.
