abstract
Shiga toxin producing E. coli has been considered an emerging food borne pathogen that causes haemorrhagic colitis, abdominal pain, and occasional fevers; along with haemolytic uremic syndrome that develops in 5-8% of cases. The main natural reservoir of shiga toxins is ruminants such as cattle and; however, faecal contamination during manual milking, along with poor hygiene practices during cheese preparation, allows for the presence of toxins in raw milk. These conversational water treatment methods of drinking water are needed to modifications for disinfection of microbes and removing their toxins from drinking water sources with very low cost, this is the main objective of this present study.
