What Bugs Me about Pesticides: A look at Pesticide Testing on Humans

Oftentimes human experimentation refers to an experimental treatment being tried out on people. What happens, however, when the test isn’t for a medicine but a poison? This is what happens with human pesticide testing. For everyone who doesn’t know, pesticides are chemicals designed to kill whatever it is that humans want dead. According to the EPA, the official definition is:

“Any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest. Pests can be insects, mice and other animals, unwanted plants (weeds), fungi, or microorganisms like bacteria and viruses…also any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant.”

Obviously, there are many chemicals that qualify for these roles, all of which have some pretty nasty effects on their intended target. The thing is, one of the most common uses of pesticides is in commercial agriculture, and there is always a possibility that some residue is left behind on the final product. That’s right! There could be pesticide in your food (unless you only eat organic). Don’t worry though; you’re not in danger of dying from pesticide poisoning. The EPA sets some pretty strict limits, just a fraction of the highest harmless daily dose, on the amount of these chemicals that can end up on food. The main issue here is a loophole: a company can get the EPA to increase the maximum amount by demonstrating that their proposed amounts have no adverse effects on humans. How do they do that? Human testing.
            Pesticide companies are arguably encouraged to entice people into taking these poisons daily in order to assess what the highest healthiest levels of exposure are. In order to determine the highest safe amount, you will inevitably have to cross the line and find the lowest unsafe amount. In 2005, a report to the EPA from two California Senators described ghastly industry-sponsored trials which included people being placed in chambers with vapors of an active ingredient of tear gas at higher than federally mandated levels, and other subjects being required to take pesticide capsules with breakfast every day during the study. Even worse is that the report also suggested that the informed consent required for the trial may have been clouded by technical jargon or incomplete in nature.
            This report was received by the EPA and some changes were made. Last year the document was amended to “expand the protections for subject in human studies research.” As a result, the EPA no longer supports studies involving pregnant or nursing women, and children. Unfortunately, this just doesn’t cut it. The exact language specifies that this rule applies to research that is “intended for submission to EPA.” However, many activist groups are worried that pesticide companies will simply conduct their studies and submit them to other nations, or to the state governments. Since the EPA is significantly influenced by other nations, this strategy could still bring about the companies desired result, minus the restrictions. Additionally the informed consent rules still seem vulnerable to exploitation by depriving potential subjects of the clear truth.
            Ideally, we could talk about banning the use of pesticides as a potential solution for this problem. Unfortunately, however, they play a large role in cheaply mass producing food. Regardless, the legislation needs to be revisited again. The existing loopholes need to be closed up to prevent as many people as possible from poisoning themselves for whatever compensation the company is offering. It would be even better if we could integrate commercial farming with some of the techniques used by organic farms in place of herbicides and insecticides. This could make it so the EPA’s limits on residue on food need not be exceeded, bringing about an end to these ridiculous human trials.

Good post. Since this is a practical issue, can you offer some practical solutions?
