Abstract


Common Fruitsand vegetables brought for sale in marketsof three districts of Maru Local government of Zamfara State were screened for intestinal helminths parasites in Parasitology Laboratory of Usmanu Danfodiyo University, Sokoto. Two thausand fourhundred (2,400) samples of eight different types of fruits and vegetables such as cabbage, lettuce, carrot, spinach, tomatoes, guava, banana and onion were obtained in three different districts markets under the Local Government Area and screened using centrifugation method. Ova and larvae of intestinal nematodes were recovered. Out of the total samples of fruits and vegetables examined, 274 (11.0%) were positive for intestinal helminths parasites. The parasites encountered includes Ascaris lumbricoides 121(05.0%), Trichuris trichiura 74 (03.0%) Hookworm 52 (02.0%) and Strongyloides stercoralis 27 (01.0%). The highest intensity of 103(12.87%) positive cases occurred in Kanoma market, while the lowest intensity of 77(9.62%) occurred in Ruwandoruwa market. The parasitic contamination of different Fruits and vegetables Show that Carrots and Spinach have the highest contamination of parasites, whereas Tomato and Onion showed the least contamination rates. None of the fruits and vegetables had single parasitic contamination. In view of these findings there is an indication that human parasites can be acquired through the consumption of these fruits and vegetables, especially when not properly and hygienically prepare before consumption.

Keywords: Fruits, Vegetables, Geohelminth, Markets, Parasites, Infection, centrifugation.
