Studies were carried out in Ibadan City, South-West Nigeria between March and June 2011, to determine the prevalence of intestinal parasites in vegetables sold in various markets within the city. Fifty samples each of 5 different vegetable types, Cabbage (Brassica deracea), Lettuce (Lactus sativa), Carrot (Daucus carota), Cucumber and green leafy vegetables were bought randomly from five different markets and examined for parasites in the laboratory using sedimentation method. Results show that 29(11.6%) out of the 250 vegetable samples examined had intestinal parasites. The prevalence of intestinal parasites in these plant tissues was found to be 22.0% in Cabbage, 14.0% in Carrot, 12.0% in lettuce and 10.0% in Green leafy vegetables. No parasites were detected in the 50 cucumber samples. Intestinal parasites detected included ova of Ascaris lumbricoides (51.7%), Hookworm larvae (27.6%) and larvae of Strongyloides stercoralis (20.7%). This study shows a high prevalence of intestinal parasites on vegetables in Ibadan markets and the need for public enlightenment campaigns on the danger of consuming inadequately washed and raw vegetables.KEYWORDS: Intestinal parasites, vegetable, market, sedimentation technique, South-West Nigeria.

Parasitological examinations were carried out during July to December, 1989, on 485 inhabitants of four villages in São Lourenço da Mata, 25 km northwest of Recife, Pernambuco, Brazil. Approximately 99.6% of the inhabitants were infected with at least one species of intestinal parasites. A high prevalence of Schistosoma mansoni (82.1%), hookworm (80.2%) Trichuris trichiura (69.9%), Ascaris lumbricoides (61.9%) and Entamoeba coli (36.7%) infections were demonstrated. Test tube cultivation revealed that the most common species of hookworm in this region was Necator americanus (88.4%), and also that the prevalence of Strongyloides stercoralis was 5.8%. Three hundred and thirty-four sera were serologically examined for amoebiasis by the gel diffusion precipitation test (GDP) and enzyme-linked immunosorbent assay (ELISA). No positive reaction was observed in all sera as examined by GDP, while 24 sera were positive by ELISA.

Background: Consumption of raw or unhygienically prepared vegetables is a potential source of parasitic infection. This study aimed to establish the prevalence and types of intestinal parasites on the freshly sold vegetables at the market. Methods: Totally, 95 vegetable samples were randomly procured from vendors at Lusaka City market (Zambia). The samples were examined for parasitic contamination using floatation and sedimentation methods. Data were analyzed using Epi Info version 7.2.4.0. Results: The overall parasitic contamination of fresh vegetables was 35.8% (34 out of 95). The highest parasitic contamination rate was found in Chinese cabbage with 7.4% (7 out of 95), followed by rape with 6.3% (6 out of 95), chilli with 5.3% (5 out of 95), pigweed with 5.3% (5 out of 95), pumpkin leaves with 5.3% (5 out of 95), tomatoes with 4.2% (4 out of 95), and cabbage with 2.1% (2 out of 95). There was a significant (p=0.001) statistically difference between the type of vegetables and the presence of the parasites. The identified helminths had different prevalence rates, including Taenia spp. with 9.5%, Trichuris trichuria with 5.3%, Ascaris lumbricoides with 3.2%, Clonorchis sinensis with 2.1%, Diphyllobothrium latum with 2.1%, Paragonimus westermani with 2.1%, and Strongyloides stercoralis with 2.1%. Also, Giardia lamblia with 24.2% and Balantidium coli with 4.2% were the protozoan parasites identified. Conclusion: This study showed that some vegetables sold at the Lusaka City market (Zambia) were a potential source of parasitic infections for local consumers. G. lamblia was the most prevalent parasite found in the vegetable samples.

Fresh vegetables are frequently used to prepare fresh salad dishes widely consumed in the world. They are known to be the main source of pathogenic intestinal parasites. In this context, the present work aimed to (a) detect the pathogenic intestinal parasites (PIP) in washed fresh vegetables, and (b) assess the exposure to PIP in the city of Ain Témouchent (Algeria). In fact, 26 samples belonging to six groups of fresh vegetables (cabbages, lettuces, leeks, radishes, peppers and tomatoes) were collected, washed (similarly to domestic wash with or without vinegar addition), then examined for PIP contamination. The results indicated that 90% of the examined vegetable samples were contaminated with intestinal parasites showing higher prevalence in lettuce (70.85%) while the lowest contamination (23.52%) was reported in pepper. In addition, Cryptosperidium (72%) has been found to be the most dominant parasite in all vegetables while Toxocara (8%) was less present. These finding are a preliminary report to conduct a risk assessment of PIP linked to vegetable feeding

The chromatographic method in combination with a Partial Least Squares (type PLS-1) chemometric tool was developed to analyse simultaneously the carotenoid compounds, lutein and zeaxanthin. Both analytes appear together in the same chromatographic peak. Different calibration matrices were done using the absorbance spectra, obtained in the peak apex. The method was successfully applied to plant material such as cabbage, broccoli, red pepper, yellow pepper, and green pepper. The higher content of lutein was found in the green leafy vegetables such as broccoli and cabbage. On the other hand, zeaxanthin was only found in pepper, with the highest concentration having been found in red pepper.

In order to verify the presence of intestinal parasites in food handlers, stool samples were collected from 104 cooks and their helpers that were working in food preparation in 20 public elementary schools, in various areas of the city of Uberlândia, Minas Gerais, Brazil. The samples were collected during the months of November and December, 1988, in plastic flasks containing a 10% formaldehyde solution and processed by the Hoffmann, Pons & Janer method. The sediment was examined using triplicate slides. All individuals were females aged between 24 to 69 years. Intestinal parasites were found in 85.0% of the studied schools and 47.1% of the studied food handlers (cooks and helpers) were found to be positive. Among the 49 infected food handlers, 32 (65.3%) carried a single parasite and 17 (34.7%) carried two parasites. The following intestinal parasites were found: Giardia lamblia (21.1%), Entamoeba coli (21.1%), hookworms (9.6%), Ascaris lumbricoides (5.8%), Entamoeba histolytica (2.9%), Hymenolepis nana (1.9%), Strongyloides stercoralis (1.0%). These data emphasize the need for a rigid semi-annual control in all school food handlers, including diagnosis, specific treatment and orientation about the mechanisms of transmission of the intestinal parasites.

SUMMARY Little is known about the frequency of intestinal parasites in the elderly due to a lack of attention given to the occurrence of these infections among older adults. This study compares the frequency of Strongyloides stercoralis and other enteroparasites between elderly living in nursing homes (n = 100) and those noninstitutionalized (n = 100) from Uberlândia, state of Minas Gerais, southeastern Brazil, associated with data of epidemiological and socio-demographic conditions. Through coproparasitological examination of both groups, enteroparasites were detected in 15 of 200 individuals examined (7.5%; CI: 5.1- 9.9). S. stercoralis was the most frequent parasite 10/200 (5%; CI: 4.2-5.8), being significantly higher in males and in individuals with autonomy for daily living activities. There were no statistical differences in the prevalence of parasites between the two groups compared. In conclusion, S. stercoralis infection was highly prevalent in elderly patients and it does not depend on whether the individual was institutionalized or not.

This study determined the prevalence of parasites on some common fruits and vegetables from major markets in Ede Town, Osun State, Nigeria. A total of two hundred and forty six (246) samples of fruits and vegetables were examined by sedimentation technique after washing using normal saline. The overall parasite prevalence was 37.4%. The highest rate of parasitic contamination (46.7%) was recorded in pineapples (Anana comosus) while oranges (Citrus sinensis) were the least contaminated (16.7%). For vegetables, African spinach (Spinacea oleracea) was the most contaminated (77.8%) while the least contaminated (2.2%) was celosia leaf (Celosia argentea). Ascaris lumbricoides was the most (21.7%) frequent parasitic contaminants on fruits and vegetables followed by Balantidium coli (19.6%) and then Hookworm (13.0%). Entamoeba histolytica and Strongyloides stercoralis had the same percentage of occurrence(12.0%) while Fasciolopsis buski (2.2%) was the least parasite found. The highest number of parasites was found in Timi Market with 46.2% fruits and 66.7% vegetables contaminated. Since eating raw fruits and vegetables is a potential source of transmission of intestinal parasites in the study area, it is important that consumers are educated on the need to always ensure proper washing of their fruits and vegetables.

Aims: To investigate the trace metals, manganese (Mn), Nickel (Ni), chromium (Cr), cobalt (Co), zinc (Zn) and iron (Fe) in vegetable samples (Telfairia occidentalis, Amaranthus viridis and Pterocarpus erinaceus) from three senatorial zones in Enugu state, Nigeria during dry season period. Place of Study: The leaf samples were collected from three senatorial zones (Enugu north, Enugu west and Enugu east) of Enugu State Nigeria. Methodology: The samples were collected fresh in January, February and March. Prior to analysis, each of the collected samples were dried at room temperature, pulverized using a ball mill and stored at room temperature. They were digested using the wet digestion method and individual metals analyzed using atomic absorption spectrophotometer. Results: The results of the findings revealed that the concentrations of trace metals in the plant tissues were in the following decreasing order Fe > Zn > Mn > Cr > Co > Cd. Amaranthus viridis had the highest accumulation of trace metals while P. erinaceus had the least. Enugu East senatorial zone had the highest accumulation of Mn and Co in all the vegetable samples while Enugu West senatorial zone showed the highest accumulation of Ni, Cr, Zn and Fe in all the plant tissues. Enugu north senatorial zone had the least level of trace metals accumulation in the three plant tissues. Manganese contamination could be a result of mining, battery and automobile fume pollution which dissolve into the soil and are absorbed by plants more effectively during dry seasons. Conclusion: To mitigate the unwanted increase of these metals in vegetables during the dry season, it is necessary to strengthen environmental waste disposal laws.
