For Ventura County and Oxnard, here's the nut of it:
Use of many of these sixty-six pesticides has fallen statewide since 2007. But a handful of communities saw a dramatic increase. By 2012, the most recent year for which data is available, more than 29 million pounds of these chemicals—more than half the total used in the state—were applied in just 5 percent of California’s 1,769 census ZIP codes, according to an independent investigation by this reporter. In two ZIP codes that Zuñiga knows well—areas that include the Oxnard High neighborhood where she trained and south Oxnard, where she lives—applications of these especially toxic pesticides, which were already among the highest in the state, rose between 61 percent and 84 percent from 2007 t0 2012, records at the California Department of Pesticide Regulation show. Both are among the ten ZIP codes with the most intensive use of these pesticides in California. And both have sizable Latino populations—around 70 percent—thanks, in part, to the large number of farm jobs in the area. The great majority of the people who work in the strawberry fields in Oxnard, which hosts the largest population of farmworkers in Ventura County, come from Mexico.
