“…Major obstacles of controlling shigellosis includes the eases with Shigella spread from person to person rapidly with which it develops antimicrobial resistance (WHO,2005). It is well established that the use of excreta-polluted irrigation water to grow vegetables is a health risk to the farmer and consumers (Zavadil, 2009). In spite of this, the use of wastewater has been used for farming purposes for many types of vegetables (Agamid et al, 1999).…”

This study was conducted to assess the extent of intestinal parasitic and bacterial contamination of raw vegetables sold at Nekemte town and collected from selected farms near to Nekemte town. Samples of three different vegetables; cabbages, lettuce and carrots were collected from Nekemte town and selected farms and all samples were examined for intestinal parasites and bacterial contamination, to determine bacterial load and prevalence intestinal parasites. The results show that cabbages were found to be the most heavily contaminated vegetable in both farms and in markets by aerobic bacteria. The highest total coliform count was also recorded from lettuce in all vegetable farms. The highest faecal coliform count was recorded in cabbage sampled from selected farms. The high microbial contamination rates associated with these vegetable samples indicated poor water quality for irrigation employed in the overall production of vegetables in the study area.

“…Very serious risks include crop yields reduction, crop quality deterioration, crop contamination with pathogens, and intestinal helminthes. It is however, possible to achieve high crop yields without the deterioration of quality using treated wastewater for the irrigation of crops under controlled conditions (Zavadil 2009). …”

In this study, raw and treated wastewaters were reused for potato cultivation in order to verify the effect of wastewater on crop yield, crop's heavy metals' concentration as well as some major traits of potato. To this regard, a completely randomized test was designed with five water treatments and three replications. The watering were as follows: raw wastewater (T 1 ), treated wastewater (T 2 ), a combination of 50 % raw wastewater and 50 % fresh water (T 3 ), a combination of 50 % treated wastewater and 50 % fresh water (T 4 ), and fresh water (T 5 ). The experiments were run during October 2009-June 2010 in the greenhouse of Bu-Ali Sina University. The results show that the effects of treatments were significant on the length and number of stems per plant (p \ 0.05). The number of nodes and weight of tubers, crop yield and heavy metal (cadmium, nickel and lead) concentration in shoots and tubers were also significant (p \ 0.01). The results indicated that the highest length of stem (55.44 cm) was obtained in T 2 which had no significant differences from that of T 1 . The maximum and minimum tuber weights and crop yield were obtained in T 1 and T 5 , respectively. Based on crop yield rate, the watering ranked as follows: T 5 . The maximum and minimum heavy metal values were observed in T 1 and T 5 , respectively. Based on the cadmium, nickel and lead accumulations in shoots and tubers (except cadmium in shoots), the watering treatments ranked as:

“…Treated municipal wastewater may prove a potential economic asset by contribution to saving water resources, irrigating agriculture land and even reducing fertilizer inputs (Fonseca et al, 2005b). In fact, the reuse of treated municipal wastewater in irrigation is an alternative to water scarcity and a means of environmental protection by reducing the discharge of water into rivers and oceans (Zavadil, 2009). It seems that in some cases high yields of the crops could be achieved without deterioration of their quality by using treated wastewater (Munir and Ayadi, 2005).…”

Treated wastewater could be considered as a new water resource in agriculture especially in arid and semi-arid regions of the world such as Iran. Two one-year field experiments were carried out to determine the effects of municipal treated wastewater on yield and seed heavy metals content of sunflower cultivars, in Research Farm of Yazd Municipal Wastewater Purification Station during 2015 and 2016. The climate of the region was hot and dry according to Koppen climate classification system. Experiment was arranged as split plot based on randomized complete block design with three replicates. Treatments were three irrigation water types as main plot consisted ("WW": irrigation with treated municipal wastewater thoroughly, "WW/FW": irrigation with treated wastewater/fresh water alternatively and "FW": irrigation with fresh water thoroughly) and three sunflower cultivars (Azargol, Record, and Farrokh) as subplots. The following parameters were assessed: plant height (cm), head diameter (cm), seed numbers per head, unfilled seeds per head, seed and biological yield (kg/ha) and seed heavy metals content. Results showed that the highest plant height (194 cm) obtained in Record and the highest head diameter (21.5 cm) obtained in Farrokh cultivars, which were irrigated by WW. Treated municipal wastewater also increased seed yield by 10.7% compared to FW treatment. The highest (5029 Kg/ha) and lowest (3734 Kg/ha) seed yield were obtained in Azargol and Farrokh that irrigated with WW and WW/FW treatment, respectively. However, application of treated municipal wastewater lead to accumulation of trace elements (Fe, Mn, Zn, Cu, Cd, Pb, and As) in seeds; but, the values of all the elements were below the permissible limits recommended by World Health Organization. It is concluded that WW could be used for irrigating sunflower crop without worrying about the accumulation of toxic substances.
