The short answer is NO.  Without treatment, raw sewage contains e.Coli, Salmonella, and other pathogens, which should not be allowed in irrigation water or fertilizer used for food crops.  However, dewatered sewage sludge can be allowed to decompose naturally (but this will give off methane and other volatiles), or better, it can be heated treated (anaerobic digestion) to decompose more quickly.  This destroys the pathogens and the sterilized sludge or compost can be used as fertilizer.  If  the methane from anaerobic digestion is captured, it can used to generate electricity (to digest the sludge.   It is very important that the sewage not contain heavy metals, which can contaminate agricultural soil.  Again, the water from untreated sewage should not be used for food crops.
