“…A. lumbricoides with (15.6%) was dominant which is in agreement with 18,20,21,22 . The reason due to presence thick cortex around ova of A. lumbricoides that give it high resistance against hard environmental 23 , and to presence mass of faece around ova of A. lumbricoides stay on it for additional period of time, as well as most of parasitic infections that transport via soil are A. lumbricoides, T. trichiura and Hook worm 24 .…”

To detect parasitic contamination of fresh vegetables and to know the extent of relationship between the prevalence of parasites on vegetables and its infection rate in the hospitals and the extent of vinegar effect (5% Acetic acid) to kill the parasites, (128) samples of six different fresh vegetable types such as Garden Cress, leek, Radish, Lettuce, Celery and Basil. And (30) additional samples from Leek were collected from local markets of two cities in Thi-Qar province. Sedimentation technique was used for samples examination. Giardia lamblia with (71.1 %) was the dominant parasite of protozoa and Ascaris lumbricoides (15.6%) was the common parasite of helminthes therefore the significant differences were found by using the statistical analysis (T-test) in level P< 0.05. One hundred and thirteen (113) samples were contaminated with parasites, Leek and Basil with rate (100%) were full contamination with parasites while Lettuce (70%) was the lower. The direct relationship wasn't found between percentage of parasites contamination for fresh vegetables in sale markets and percentage of intestinal parasitic infections in hospitals that near of its. There was relationship between the higher rate of prevalence G. lamblia and E. histolytica on fresh vegetables and infection of these parasites in the hospitals. No significant differences between rate of infection for male and rate of infection for female by using (T-test) in level P< 0.05. There were some parasites such as Diphyllobotherium latum, Schistosoma japonicum, Heterophyes heterophyes that are rarely or not found in Iraq were isolated from contaminated samples and this indicates to irrigation it by water contaminated with sewage or fertilization it with faces of foreign people that coming to work in Iraq and biodiversity upset and occurrence of new species did not exist in Iraq at the expense of other types. There was positive effect for vinegar (5% Acetic acid) to kill the most parasites except cysts of G. lamblia and ova of E. vermicularis.

Background. Helminths are significant contributors to global health problems. Subgroup soil-transmitted helminths are among the listed neglected tropical diseases. The rural inhabitants often suffer from heavy infection, particularly children and pregnant women. Objective. The study aimed at determining the magnitude and intensity of soil-transmitted helminth infection and associated risk factors in the study area where the prevalence and intensity of the infection are yet unknown at the community level. Method. A community-based cross-sectional study was conducted between April and June 2016 on 377 individuals. Systematic random sampling was utilized to select the households. Lottery method was used for study subject selection in the households. Sociodemographic and risk factor data were collected using a pretested questionnaire. Parasitological tests were processed using Kato-Katz thick smear and duplicate direct wet mount analysis of the stool sample. Results. A total of 377 subjects aged from 2 to 55 years were enrolled in the study, of which 211 were female (56%) and 166 were male (44%). The overall prevalence of soil-transmitted helminths was 265 (70.3%). The females shared more (36.6%, 138) as compared to males (33.7%, 127) at P<0.05. Of all identified soil-transmitted helminths, Trichuris trichiura was the predominant infectious agent (66.8%, 252) followed by Ascaris lumbricoides (16.4%, 62) and hookworm (14.1%, 53). Gender (AOR: 1.67 (95% CI: 1.034–2.706)), lack of fruit washing before consumption (AOR: 1.7 (95% CI: 1.1–2.6)), open defecation habit (AOR: 1.75 (95% CI: 0.921–3.338)), and drinking untreated water (AOR: 1.994 (95% CI: 1.019–3.90)) were significantly associated with soil-transmitted helminth infection. Conclusion. High prevalence of STH infection was still an important health issue of the community even after the implementation of the health extension program. Hence, intervention considering all population of the residents as eligible to deworm and health education are mandatory.

“…Human infection occurs through consumption of raw vegetables. 1,2 Epidemiological studies have indicated that in areas of the world where helminthic diseases are endemic and where raw untreated waste water is used to irrigate vegetables generally eaten uncooked, the consumption of such waste irrigated vegetables may lead to parasitic infestation. 3 Bad hygienic practice during transport, processing and preparation by handlers including consumers could also contribute to vegetable contaminations.…”

Introduction: Fresh vegetables are an important source of vital nutrients. Poor farming practices and improper washing put consumers at risk of parasitic infections. This study explored the presence of parasitic contamination of commonly-consumed vegetables procured from two markets in Ghana. It also explored the decontamination effects of washing vegetables with different concentrations of saline solution. Method: Vegetables were procured from two major open markets in Koforidua, Ghana. Vegetables were thoroughly washed twice using 0.0%, 0.45%, 0.9%, 1.5% concentrations of saline solutions. The deposits were examined under the light microscope for the presence of parasites. Smears were made from sediments, stained and observed with Fluorescence microscope to detect any spores or oocysts of Microsporidium sp., and Cryptosporidium sp. Result: Three hundred and sixty of five types of vegetables were procured. Two hundred and seven (57.5%, 95% Confidence Interval 52.2%-62.7%) were found to be contaminated with at least one type of parasite. The extent of vegetable contamination was 97.2% (90.3-99.7) of spring onions, 70.8% (58.9-81.0) of lettuce and 50.0% (38.0-62.0) of tomatoes. The commonest parasites were Strongyloides stercoralis (36.4%, 31.4-41.6), Balantidium coli (13.6%, 10.2-17.6) and Cryptosporidium oocyst (11.1%, 8.1-14.8). Parasite recovering rates were 57.5% (52.2-62.7) and 42.2% (37.1-47.5) after first and second washings respectively. Conclusion: The level of parasite contamination is high and consumption of raw vegetables procured from these markets carry a high risk of parasite infection. Washing vegetables twice with saline was not effective for parasite removal. Improved approaches for washing vegetables before consumption are needed.
