“…This results support those previous studies which found fruits and vegetables contaminated with geohelminth ova and larvae [4,7,16,17]. They concluded that the sources of fruits and vegetables were contaminated with fecal matter.…”

Various species of parasites are capable of contaminating most edible fruits and vegetables consumed in Lokoja with chronic consequences leading to malnutrition, iron-deficiency anaemia, morbidity and sometimes, healthcompromising nutritional status and affective cognitive process (especially in children). This assessment was done to isolate and identify common parasites of public health importance, given their high rates of transmission among members of the community, especially the fruits and vegetable consumers; as well as provide data and evidence for surveillance of some soil-transmitted helminthes and foodborne disease parasites. A total of 128 fruits and vegetables were sampled from the four markets, parasites were isolated from samples by washing with distilled water and normal saline. The isolates were examined for contamination using light microscopy. Concentrations of identified parasites were determined using iodine smear and sedimentation methods. 82 of the 128 samples were contaminated with different parasitic stages including ova, cysts, and larvae of Taenia sp., Ascaris lumbricoides, Schistosoma mansoni, Enterobius vermicularis, Hookworm; Balantidium coli, Entamoeba histolytica, Entamoeba coli; and Strongyloides stercoralis. Fruits and vegetables from different markets showed significant levels of parasitological infestation with Lonkongoma (78%) having the highest level compared to Ganaja (75%), Adankolo (56.25%) and Old Market (53.13%). Among the fruits and vegetables examined, pumpkin (41) had the highest frequency of parasitological contamination, with watermelon (21), garden egg (8) and green peas (8). Implications of these findings for effective surveillance programmes of foodborne and neglected tropical diseases of great public health importance were discussed and further control measures recommended.

“…Vegetable consumers and agricultural workers are a major target of these infections. Nine species of parasites recorded in this study have been reported as frequent gastro-intestinal parasites in many parts of Nigeria (Umoh et al, 2001;Opara and Udoidung, 2002;Netanya and Njom, 2003;Uga et al, 2009;Ogunleye et al, 2010). Amaechi, E. C., Ohaeri,C.C., Ukpai,O.M and Adegbite, R. A (MEJS) The persistent occurrence of these parasites suggests a high level of contamination and long-time transmission; however the occurrence of these parasitic species in various salad vegetables varied.…”

“…According to Umoh et al (2001) the rate of contamination of food is dependent on the sanitation in a particular environment and sanitary habits of people living in such environment. This is also in line with the result of this study which also showed that the parasite occurrence varied with market location.…”

Fresh salad vegetables are essential for good health and they form a major component of human diet in every family in Nigeria. Raw vegetables can be agent of transmission of intestinal parasites. The aim of this study is to determine the parasitic contamination of salad vegetables sold at wholesale and retail markets around Ilorin metropolis. A total of 150 samples of salad vegetables obtained from five different markets were examined for both protozoa and helminth parasites using standard methods. About 25 samples each of lettuce, cabbage, carrot, cucumber, tomato and onion were examined. Eggs of Ascaris lumbricoides, Entamoeba histolytica/dispar, Enterobius vermicularis, cysts of Giardia lamblia, Fasciola hepatica, Trichuris trichiura, Strongyloides stercoralis, Balantidium coli and Necator americanus were detected in 28.0%,

“…In Zaria, as in most regions of northern Nigeria, and as in many developing countries with inadequate sanitation, drinking and irrigation waters are sourced mainly from surface waters, including lakes, dams, rivers and streams that are vulnerable to faecal contamination (Shuval 1990; Barbier and Thompson 1998;Byamukama et al 2000;Agbogu et al 2006;Chuo 2009). The use of raw and treated wastewater for the irrigation of fresh produce is also a common practice in these areas (Shuval 1990;Umoh et al 2001;Chigor et al 2010a;Okibe et al 2010) and records at Ahmadu Bello University Teaching Hospital, Zaria show that enteric and waterborne infections are prevalent in Zaria (unpublished data). Studies have also shown that the hygienic quality of drinking water as delivered to consumers in the area is unsatisfactory (Dada et al 1990).…”

We assessed the quality and pollution status of source surface waters in Zaria, Nigeria by monitoring the nature, cause and extent of pollution in Samaru stream, Kubanni River and Kubanni dam over a period of 10 months, between March and December 2002. A total of 228 water samples was collected from 12 sites and analysed for a total of ten physicochemical and one bacteriological quality indicators, using standard methods. Aesthetic water quality impairment parameters were also observed. The mean values of most water quality parameters were significantly higher (P < 0.05) in both the stream and river than in the dam. There was no significant correlation between faecal coliform counts (FCC) and water temperature (in the range 15-33°C); pH (5.77-7.32); and turbidity (1.4-567 NTU). The high FCC ranged from 2.0 × 10(1) to 1.6 × 10(6) MPN/100 ml and exceeded the WHO standards for drinking water and water used for fresh-produce irrigation, and correlated positively (P < 0.05) with conductivity (in the range 68-1,029 μS/cm); TDS (10.0-70.0 mg/l); TSS (10.0-70.0 mg/l); Cl (7.5-181 mg/l); PO(4)(-) P (0.01-0.41 mg/l); NO(3)(-) N (0.6-3.8 mg/l) and BOD(5) (0.1-14.9 mg/l). The main pollution sources were municipal wastewater, stormwater runoffs, the ABU sewage treatment plant, abattoir effluents and irrigation farms treated with chemical fertilisers. We conclude that these water bodies are potentially hazardous to public health and that proper sewage treatment and river quality monitoring are needed to warn against hazards to public health.
