A label stating ‘Produce of USA’ is wrapped around a bunch of organic carrots at a farmers market |
Consumers of organic foods are getting both more and less than they bargained for. On both counts, it’s not good.
Many people who pay the huge premium often more than 100% for organic
foods do so because they’re afraid of pesticides. If that’s their
rationale, they misunderstand the nuances of organic agriculture.
Although it’s true that synthetic chemical pesticides are generally
prohibited, there is a lengthy list of exceptions
listed in the Organic Foods Production Act, while most “natural” ones
are permitted. However, “organic” pesticides can be toxic. As
evolutionary biologist Christie Wilcox explained in a 2012 Scientific American article
(“Are lower pesticide residues a good reason to buy organic? Probably
not.”): “Organic pesticides pose the same health risks as non-organic
ones.”
Another poorly recognized aspect of this issue is that the vast
majority of pesticidal substances that we consume are in our diets
“naturally” and are present in organic foods as well as
non-organic ones. In a classic study, UC Berkeley biochemist Bruce Ames
and his colleagues found that “99.99 percent (by weight) of the
pesticides in the American diet are chemicals that plants produce to
defend themselves.”
Moreover, “natural and synthetic chemicals are
equally likely to be positive in animal cancer tests.” Thus, consumers
who buy organic to avoid pesticide exposure are focusing their attention
on just one-hundredth of 1% of the pesticides they consume.
Some consumers think that the USDA National Organic Program (NOP)
requires certified organic products to be free of ingredients from
“GMOs,” organisms crafted with molecular techniques of genetic
engineering. Wrong again. USDA does not require organic products to be
GMO-free. (In any case, the methods used to create so-called GMOs are an
extension, or refinement, of older techniques for genetic modification that have been used for a century or more.) As USDA officials have said repeatedly:
Organic certification is process-based. That is, certifying agents attest to the ability of organic operations to follow a set of production standards and practices which meet the requirements of the Organic Foods Production Act of 1990 and the [National Organic Program] regulations .
If all aspects of the organic production or handling process were followed correctly, then the presence of detectable residue from a genetically modified organism alone does not constitute a violation of this regulation.
