E. coli in urinary tract?

it is possible when you had a bowel movement and was wiping some e coli entered your urinary system even though you wipe front to back all it takes is for one e coli bacteria to enter urinary system to cause problem e coli can be on raw meat so if you had touched raw meat then went to bathroom without washing hands before hand could happen also the bacteria could have been on door handle anything you touched before going to bathroom and wiping yourself that is why i wash before and after i use bathroom
