UPDATE: We find it important to mention that though glyphosate has been found to not contribute to cancer by the EPA, some independent groups have their doubts about the safety of this chemical, and it’s true that we are not fully aware of what long-term exposure to glyphosate does. The article has been revised accordingly.
Cancer is scary, carcinogens scarier. The uncertainty behind many common carcinogens and chemicals–what leads to cancer after prolonged exposure and what doesn’t–is certainly stressful, which is why extensive studies into different suspected cancer-causing chemicals is essential.
Sometimes, before concrete evidence can be found, suspected carcinogens spark widespread panic. Glyphosate is one such suspected carcinogen. A common chemical found in RoundUp weedkiller, the ingredient has been linked to alleged negative health effects for years. Glyphosate works by blocking enzymes in certain plants, effectively regulating weeds that would otherwise leech crops of their nutrients.
Recently, Monsanto, the conglomerate that produces RoundUp, was hit with several lawsuits, including one from a customer who had used the weedkiller for decades–and claimed that his cancer diagnoses was a result of long-term exposure to the glyphosate in the product. The federal jury overseeing the case ruled in the man’s favor. Monsanto has, so far, appealed all of the lawsuit rulings.
Glyphosate touches more than just weeds in lawns–it’s the most-used herbicide in US agriculture. It also may not be as dangerous as we thought: studies from the US Environmental Protection Agency suggest that glysophate is not, in fact, a carcinogen. They say that there is not much evidence linking glyphosate exposure to the development of cancer cells, and the EU, following thousands of peer-review studies, has long sanctioned glyphosate herbicides as safe for general use.
Of course, glyphosate–and weedkiller in general–should not be ingested in any way, and basic caution is recommended when handling the product. While the risk of developing cancer from spraying away a cluster of dandelions from a front-porch garden may be slim to none, the health effects of larger, long-term glysophate exposure is still up for debate.
