     The health risks of the use of wastewater in agriculture

Proven research that sewage contains many microbes (especially causing diseases typhoid and Elaborative, cholera, dysentery and gastroenteritis, as well as Villain pathogens (such as Cascaras, etc.) in addition to the viruses that cause serious illnesses ranging number of pathogenic microbes in the water before being processed to 510-710 microbial cell in every cubic centimeter water and after treatment decreases the number increased by 90-99%, and that many of the pathogens and the existing water continues its activity and duration Backdate soil to several weeks or months as those microbes move to cultivated crops, which have been very popular and injuring humans and animals out.

Depending on many factors such as soil type and content Ruby by the acidity of the soil and the type of crop grown and the temperature of the growing season and the quantities of fertilizer added and others and therefore must know when perhaps another few until the crop for consumption even underestimate the possibility of contamination of the crop pathogens The following table shows the survival of some pathogens crop and soil and clear the table quality crops that can be grown using wastewater and shows the need for the exclusion of leafy vegetables, or those that are eaten without cooking because of the seriousness Thousandths.
