From the page: "USDA Testing Finds 30-Plus Unapproved Pesticides on the Herb Cilantro
"Just in time for cookout season, some unsettling news arrives for guacamole and salsa lovers: Federal testing turned up a wide array of unapproved pesticides on the herb cilantro 窶" to an extent that surprises and concerns government scientists.
At least 34 unapproved pesticides showed up on cilantro samples analyzed by the U.S. Department of Agriculture as part of the agency's routine testing of a rotating selection of produce. Cilantro was the first fresh herb to be tested in the 20-year-old program.
'We are not really sure why the cilantro came up with these residues,' said Chris Pappas, a chemist who oversees the Virginia-based USDA pesticide testing. Researchers suspect growers may have confused guidelines for cilantro and flat-leaf parsley, for which more pesticides are approved.
In all, 94 percent of the 184 cilantro samples tested in 2009 came up positive for at least one pesticide, according to an annual Pesticide Data Program report posted online last week.
Chris Campbell, a pesticide analyst for the Environmental Working Group, an advocacy organization, said data show that 44 percent of cilantro samples had residues of at least one pesticide not approved for use on that crop 窶" 'higher than I have ever seen' in nearly a decade of analyzing the USDA's pesticide reports.""
