Why Is Roundup Still Being Sold?

Research suggests that glyphosate, the active ingredient in Roundup, is likely a human carcinogen, making the herbicide potentially unsafe. However, controversy surrounding its safety continues, and the product is still widely available in the U.S. for consumer and industrial use. The U.S. Environmental Protection Agency once classified glyphosate as possibly carcinogenic but later reclassified the product as safe for humans.

Safety concerns over Roundup remain. The World Health Organization classifies glyphosate as probably carcinogenic to humans based on studies involving human herbicide exposure.

Evidence suggests that the herbicide has short- and long-term adverse health effects, with Roundup exposure symptoms that include impacts to the nervous system and non-Hodgkin’s lymphoma. Despite the evidence, the EPA maintains that glyphosate — and therefore Roundup — is “not likely to be carcinogenic to humans.”

According to a University of Washington meta-analysis of existing research, the carcinogenic implications of glyphosate exposure are more substantial than previously indicated. Furthermore, a Swiss study confirmed that glyphosate raises the risk of non-Hodgkin’s lymphoma. Another systematic review also found that the existing evidence suggests that glyphosate exposure significantly increases the risk of NHL, further noting:

In addition to NHL, a 2022 literature review suggests that glyphosate may also increase the risk of breast cancer in humans. Overall, the most recent evidence suggests that Roundup’s links to cancer are stronger than the EPA indicates in its classification of glyphosate as not likely carcinogenic to humans.

Even if Roundup may be linked to cancer, it is still on the market in the U.S. because the EPA has not changed its classification for glyphosate. According to the EPA’s information about glyphosate, Roundup is safe to use. Though some studies have shown Roundup may cause health issues, not everyone who uses Roundup will be affected.

Roundup products effectively control weeds and maintain aesthetically pleasing lawns. As long as the product remains available to purchase, consumers may continue using it. Bayer is releasing newer Roundup formulations that don’t contain glyphosate.

Though Roundup with glyphosate is still available for commercial use, Bayer has announced that it will stop selling Roundup with glyphosate for residential use in 2023. Bayer, Roundup’s parent company, posted a negative global sales outlook for 2023, largely because of declines in the sale of products containing glyphosate.

The timing for a Roundup ban in the U.S. is uncertain as legislation struggles to gain wide acceptance. However, Congressional proposals continue, including the Protect America’s Children from Toxic Pesticides Act from U.S. Representative Jim McGovern that seeks to ban 70 pesticides, some already forbidden in other countries.

Bayer’s lobbying efforts are considerable, creating roadblocks and stalling efforts to ban Roundup in the U.S. and blocking a ban on Roundup in Thailand. However, individual states in the U.S., some countries and the European Union are evaluating their approvals for glyphosate, creating an uncertain future for Roundup.

While the likelihood of a ban on glyphosate in the U.S. is unclear, Roundup cancer lawsuits against Bayer have caused the company to take action by removing glyphosate from products used in home lawns and gardens. This action is not because of any acknowledgment of the product’s harmful effects but solely to avoid future litigation, according to the company’s “Five-Point Plan to Close the Roundup Litigation” announced in May 2021.

As of October 2023, Roundup products containing glyphosate are still widely available online and in brick-and-mortar stores from retailers such as Lowe’s, Tractor Supply, Walmart, Ace Hardware, Home Depot and Amazon. Bayer is also prepared to mitigate the damages through Roundup lawsuit settlements.

Consumers who have unused Roundup products they wish to get rid of need to follow guidelines for disposal. Despite the EPA’s classification of Roundup as a safe product for household and industrial use, it is hazardous. Household product disposal may differ from industrial product disposal.

Getting rid of unwanted Roundup requires care to reduce the likelihood of toxins entering the environment, potentially creating additional human and ecological hazards. However, every state has its own guidelines for disposing of household hazardous waste.

The EPA suggests contacting the local waste management authorities or contacting Earth 911 at 1-800-CLEANUP or earth911.com.

Alternatives to Roundup provide a safe and effective means of maintaining lawns and gardens. These products may utilize acetic acid, iron or essential oils to help keep weeds and pests under control.

In addition to alternative applications, consumers can implement other measures to control weeds. Mechanical methods include manually pulling weeds or using a flame-weeding machine. Those living on larger properties can consider keeping goats or geese. Finally, planting native ground cover and grasses generally creates an environment less friendly to weeds than turf grass.
