Most of the produce sampled during 2013 by the California Department of Pesticide Regulation had little or no detectable pesticide residue.
As part of its annual sampling program, the state tested 3,483 samples of fruits and vegetables sold at farmers markets, wholesale and retail outlets, and distribution centers statewide.
More than 155 different fruits and vegetables were sampled to reflect California's diverse populations, according to a news release.
The results showed that 95 percent of the samples either had no residues or residues within the allowable limits.
• Broken down, 43.53 percent had no detectable pesticide residues;
• 51.51 percent had residues within legal tolerance levels;
• 3.99 percent had illegal residues of pesticides not approved for use on the commodities tested;
• 0.98 percent of the samples had illegal pesticide residues that exceeded established tolerances.
Among the items that frequently had illegal pesticide residues were cactus pads from Mexico, ginger from China, snow peas from Guatemala and spinach from the United States.
Most of the illegal pesticide residues found in 2013 were on imported produce and were at levels that didn't post a health risk.
An exception was cactus pads that were tainted with an organophosphate pesticide at levels that potentially could sicken people who consumed it, according to the release.
