Fourteen farm workers in Kern County have been treated for exposure to a chemical after a presumed case of pesticide drift early this morning near Bakersfield. Kern County Public Health officials say the incident took place near Gosford Road and Taft Highway. The source of the pesticide is not known, but an adjacent field had been treated with a soil fumigant just yesterday. Kern County fire and hazardous materials teams also responded and treated workers who were exposed to the chemicals.
