parasitological examination of some ready to eat fruits sold at oye emene enugu state nigeria
ABSTRACT
Some locally available fruits (garden egg, orange, banana, guava, avocado, pawpaw and pineapple).sold in Oye Emene Enugu, Enugu State was examined for parasitological contamination. A total of 87 samples were examined using sedimentation and concentration methods. 11(12.6%) of the 87 fruits were positive for intestinal parasites microscopically. Among these fruits, guava had the highest number of intestinal parasites which was 6 (35.3% positive and the lowest was banana 2(8%). Parasite implicated were ova of Ascaris lumbricoides 8(9.2%), cysts of Amoeba 3(10%), yeast cells were seen on pineapple and water melon. There is no significant difference between the two methods used. Results of the current study shows a significant level of fruits contamination with pathogenic parasite from different places in Oye Emene in Enugu, Enugu State suggesting existence of a great risk of acquiring intestinal parasites by eating improperly washed fruits.
