Intestinal Parasites among Waste-Handlers in Jos Metropolitan Area of Plateau State, Nigeria

Okoronkwo O Mba

Abstract


Solid waste management is associated with health hazards. The objective of the study was to describe and quantify the type of parasitic infections among waste handlers using formol-ether concentration technique. Stoll egg count method was adopted in the quantitation of the cysts and eggs.


The frequency of parasitic infestation among waste-handlers were as follows: technical staff, (53.3%) drivers, (81.8%) refuse-van loaders (69.3%), street sweepers (63.5%) and barrow-pushers 80.0%. Entamoeba histolytica was found in 18.2% of drivers, 3.5% refuse-van loaders and 10.0% of barrow pushers. Giardia lamblia was detected in 10.0% of barrow-pushers alone. About 2.3% of van-loaders were infected with Balantidium coli. Ascaris lumbricoides eggs were detected in 5 (16.7%) technical staff, 14 (15.9%) van-loaders, 3 (15.0%) barrow-pushers, 11(14.9%) street-sweepers and 3 (13.6%) drivers. Ancylostoma duodenale infected 7 (31.8%) drivers, 24 (32.4%) street-sweepers and 6 (30.0%) barrow-pushers. About 3 (10.0%) technical staff, 9 (10.2%) refuse-van loaders, 8 (10.8%) street sweepers and 2 (10.0%) barrow-pushers were infected by Schistosoma mansoni respectively Hymenolepis nana infected only 3 (10.0%) of technical staff, while Trichuris trichiura eggs were found in 5 (4.6%) refuse van-loaders, 4 (5.4%) street-sweepers and 1 (5.4%) barrow-pushers. Parasite egg intensity was, however, low with Ascaris lumbricoides showing 86,226 +795 eggs per gram (epg),Ancylostoma duodenale 17,352+156 epg, Trichuris trichiura 1295+219 epg and Hymenolepis nana 265+44 epg.


Waste disposal workers are at high risk of infection with different species of intestinal parasites.
