PARASITOLOGICAL EXAMINATION OF SOME READY TO EAT FRUITS SOLD
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.

INTRODUCTION
Among horticultural crops, fruits are of great importance for an adequate and balance human diet. In certain part of the world, fruits are the major dietary staple. Apart from being a rich source of vitamins, and minerals, the production of fruits also contributes significantly to regional and national economics through national and international trade. The term fruit has many different meaning depending on the context.
A fruit is a ripened ovary together with seeds of a flowering plant. Fruits are the means through which flowering plants disseminate seeds (Lewis, 2002).
In cuisine when food items are called “fruits” the term is most often used for those plants fruits that are edible, sweet, and fresh examples are: apples, and oranges.
Fruits are cultivated in areas where the environmental factors are suitable for their growth. Emene in Enugu state is considered one of the areas that have good cultivating land for great yield of fruits and this is done usually during rainy season or use of irrigation during dry season. Irrigation water is achieved by different sources like lake, stream, river, ponds etc. which may be polluted with animal and human feaces. Due to high number of eggs, cyst and larvae of human intestinal parasites present in the waste
water, the use of excreta polluted water is a health risk to both the farmers and the consumers that eat the produce raw and fresh, like apples, guava, pear and mango (Scolf, 1992).
