Hill,
there is no denying the fact that you should watch where you stay, what you eat and drink when you are in Inida.
Millions visit India every year, some to get treatment for various diseases for which the treatment costs are prhibitive in the West. The long waiting lists in the hospitals of USA and UK also result in many patients coming to India for treatment.
Would this be possible if the hospitals in India were not clean and didn't maintain international standards?
Likewise the hotel you stay, the food you eat and the water you drink should be clean. You can stay in good hotels avoid wayside food and drink bottled water sold by Pepsi and Coke.
Enjoy your trip to India.
