A trip to the kitchen sink to wash ones hands could be all it takes to keep germs at bay, according to an expert.UK hygiene pioneer Dr Val Curtis of the University of London says that keeping hands clean is hugely important in preventing the spread of bugs and viruses, reports the Times.Dr Curtis identified the fact that while people claim they understand the importance of this kind of hygiene and would maintain they stick to it on a regular basis this might not always be the case.We all wash our hands in principle, but in practice, weve all got an excuse, she says.In the kitchen, bacteria from unwashed food and raw meat can be easily spread even after they are washed if manual hygiene is not respected.A beautiful model such as a fragranite sink from Franke can make hand-washing easy and even a pleasure, with its striking design and innovative material construction.
