The Canadian Food Inspection Agency conducted a 5 year study that analyzed over 4200 fresh leafy vegetable samples including domestic and imported.
In 2009-2010, 12 samples were deemed unsatisfactory because of salmonella, listeria and generic e coli.
The CFIA as part of routine testing says more than 99.9 per cent of leafy green vegetables are safe to consume and contain no detectable levels of bacterial pathogen.
