Seriously inadvisable! I contracted a serious bout of e-coli once, after a visit to a dodgy chinese restaraunt at the end of a night-out in London.
Nine painful weeks in hospital & after that, well over a year of regularly feeling utterly washed-out & awful, thanks to the ongoing effects of the secondary toxins it leaves in your system. Which can't be treated by antibiotics or anything else, they just have to burn-out in their own time.
