The Food Standards Agency (FSA) has published the largest-ever nationwide survey of the food hygiene knowledge of workers in the catering industry - with worrying results. The survey of over 1,000 workers and managers in small independent catering businesses revealed that more than a third of staff (39%) are neglecting to wash their hands after visits to the lavatory whilst at work. The research also demonstrated that half of all those interviewed (53%) did not appear to wash their hands before preparing food.
