She says scientists have estimated that 99 percent of food-borne illnesses from leafy greens can be traced back to disinfection issues. 'In a sense the leaf is protecting the bacteria and allowing it to spread,' said Nichola Kinsinger, a post-doctoral researcher working with Sharon Walker, a professor of chemical and environmental engineering. 'It was surprising to discover how the leaf surface formed micro-environments t...
