Consumers could soon be able to test their own foods for the presence of pesticides with a simple litmus-like paper "dipstick" that you merely dip into the food and watch for a distinctive color change in less than 5 minutes.
Detecting pesticides in foods today is a complicated process involving sophisticated test equipment that can take hours to detect and measure the amount of contamination. Now a new paper test strip method has been developed that permits consumers to test their own foods for contamination by common pesticides, according to professor John Brennan, who developed the new test method with colleagues in the Department of Chemistry and Chemical Biology at McMaster University (Hamilton, Ontario).
