Abstract

To know the Epidemiological of parasites that contaminated fresh vegetables, 128 samples of six types of fresh vegetables such as Garden Cress, Leek, Radish, Lettuce, Celery and Basil were collected from local markets of two cities in Thi-Qar province during the period from the first of November 2012 to the end of April 2013. Sedimentation technique was used for samples examination. The highest percentage of parasites which feature in some those vegetables more than others parasites were as follow G. lamblia with rate (91.7%) followed by T. hominis (62.5%) in Leek, A. duodenale (58.3%) in Basil . As for the highest percentage of parasites in each one month were as follow G. lamblia (100%) and E. vermicularis ( 45.8% ) in November , T. hominis (70% ) in December , G. lamblia (70%) in January , T. hominis 60% in February , G. lamblia (70.8%) and E. histolytica (45.8%) in March , G. lamblia (90%) and B. coli (70%) in April. As for the highest percentage of parasitic contamination of vegetables was (100%) in November and April and the lowest percentage was (%70) in February. The study has been recorded presence of each Diphyllobotherium latum , Schistosoma mansoni and Schistosoma japonicum in spite of absence its intermediate host from the region of study. The conclusion of this study that there is a certain types of parasites prefer certain types of vegetables as well as certain months to reach the summit prosperity (it must be noted that the change of the weather or the appearance or disappearance of cheerleaders pollution does mean nothing compared with obligation to the right environmental rules). And the possibility of isolation A. duodenale from Basil for the purpose of conducting the necessary studies against that parasite which poses a threat on the health of who exposed to it . The presence of some parasitic species which eliminates the presence of its host represent indicator on the use of untreated sewage in watering and fertilizing farmland.
