I'm just guessing, but apparently, USDA hasn't bothered to check for chemicals on cilantro in over 20 years, and when they finally got around to it, the results were surprising, to say the least:
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.
Gee, I wonder why so many people are having health problems, these days.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.
