Researchers have found that bacteria thrive in some pesticides, the New Scientist reported.
Bacteria breed in pesticide storage tanks and are then sprayed on to foods and fruits such as lettuce and strawberries, according to the hypothesis put forward by Canadian scientists.
The research team from the University of Manitoba, Winnipeg, led by Greg Blank, tested about a dozen common pesticides with bacteria that included salmonella, shigella, listeria and E. coli 0157:H7.
They found that bacteria thrived in about a third of the pesticides. The fungicide chlorothalonil, the weedkiller linuron and the insecticides permethrin and chlorpyrifos all proved especially amenable environments.
The most potent combination was that of salmonella, E. coli or shigella with chlorothalonil.
"Numbers could increase one thousand-fold," Greg Blank said.
A British crop expert Ross Dyer, technical manager of the Crop Protection Association, told the journal that dirty water - used for irrigation - was a bigger problem than pesticides.
