Personally, I use Dettol spray a lot...I feel happy that I've sanitised whatever area I'm about to use or have just used, for food prep. So easy with the spray. I accept that we don't want to kill 'good bacteria' along with the bad, however kitchen hygiene is far too important to be left to chance IMHO. Like Bronwen417, I always run a bowl of very hot soapy water ready for a good handwash after handling raw poultry or meat - otherwise you're just transferring any potential nasties to the taps and so forth. I always keep one Dettol spray under the sink and one in the bathroom, plus some original dettol for occasional use if anyone is unwell and has to use the 'sick bowl'...the smell always takes me back to my own childhood when the smell was very reassuring if one was poorly! I empty the fridge every ten days and wash the shelves and salad drawers - it's surprising how much gunk can build up in the salad drawers if berries or soft fruit and veg escape their protective wrapping and roll off into a corner!
I know that our Grandmothers didnt have all these 'mod cons' to keep food poisoning and germs at bay and would probably have raised an eyebrow at all our 'lotions and potions' but speaking for myself, I'll take all the help I can get!
