Roundup is the most commonly used weed killer on farm crops and household lawns in the US. It has been linked to thousands of illnesses and diseases over the years, including non-Hodgkin's lymphoma, a type of cancer that starts in the lymphatic system. Other symptoms of Roundup poisoning include dizziness, headaches, vomiting, and difficulty breathing. Long-term exposure to the pesticide can lead to even more severe health concerns, including neurological disorders that lead to neurodegenerative diseases such as Alzheimer's, autism, and ADHD. While the Environmental Protection Agency (EPA) in the US has stated that glyphosate, the active ingredient in Roundup, is unlikely to cause cancer, the International Agency for Research on Cancer (IARC) has classified it as probably carcinogenic to humans.

Glyphosate, the active ingredient in Roundup, is toxic to humans
Glyphosate is the declared active ingredient in most versions of Roundup. Roundup is the most commonly used weed killer on farm crops and household lawns in the US. It is a glyphosate-based herbicide that works by inhibiting plants from producing essential proteins necessary for their growth.
Glyphosate is toxic to humans. Short-term exposure to glyphosate is not a significant concern, but long-term exposure may be. Scientists are divided on the level of risk involved, as studies have shown conflicting results. However, most studies have involved animals, not humans.
Glyphosate exposure has been linked to several health issues in humans. Firstly, it has been associated with cancer. The International Agency for Research on Cancer (IARC) has classified glyphosate as "probably carcinogenic to humans". Studies have also found links between glyphosate and non-alcoholic fatty liver disease, metabolic syndrome, cirrhosis, and chronic kidney disease.
Secondly, glyphosate exposure has been linked to neurotoxic effects. Research has shown that exposure to glyphosate during the early stages of life can affect normal cell development, leading to alterations in neuronal growth and myelination. It has also been associated with visual memory impairment in Ugandan smallholder farmers.
Thirdly, glyphosate exposure may cause digestive issues. A 2020 study found that a majority of gut bacteria may be susceptible to glyphosate, which could affect the human gut microbiome. Another study found that low-dose glyphosate exposure alters gut microbiota composition and modulates gut homeostasis.
Finally, glyphosate has been linked to endocrine and reproductive issues. A 2024 study connected glyphosate levels to infertility in men.
It is important to note that regulatory agencies disagree on the level of risk posed by glyphosate. While the IARC has classified it as probably carcinogenic, the Environmental Protection Agency (EPA) in the US states that glyphosate is unlikely to cause cancer in humans when used according to directions.
To protect against glyphosate exposure, it is recommended to always wash your hands carefully after using glyphosate or touching sprayed plants. Wear protective clothing, such as long sleeves and pants, and avoid spraying on windy days to prevent the spray from blowing onto your skin. Do not eat, drink, or smoke while using glyphosate, and avoid walking barefoot in treated areas for at least 24 hours.

Roundup exposure may cause neurological disorders, including autism and Alzheimer's
Roundup is the most commonly used weed killer in the US, both on farm crops and household lawns. It is a glyphosate-based herbicide, with glyphosate being its declared active ingredient. Roundup also contains a variety of other ingredients, including those designed to help the herbicide stick to plants and be absorbed into the roots.
Roundup exposure has been linked to thousands of illnesses and diseases over the past several decades. The symptoms of poisoning can range from mild to severe, and can include dizziness, headaches, vomiting, and breathing difficulty. Long-term exposure to the pesticide can lead to even more advanced health concerns.
Recent research has found possible associations between Roundup exposure and neurological disorders, including autism and Alzheimer's disease. Glyphosate has been shown to disturb the healthy bacteria in the gut biome, which play a vital role in regulating healthy brain functioning. Glyphosate crosses the blood-brain barrier and causes inflammation, negatively impacting the regulation of neurological processes and causing neurodegenerative disorders. In addition to autism and Alzheimer's, glyphosate-caused genetic damage has also been associated with anxiety and depressive-like behaviors in recent studies. Animal studies also suggest that exposure to glyphosate in utero may have adverse effects on the neurological development of unborn children.
Roundup exposure may also lead to other neurological disorders such as Parkinson's disease and attention deficit hyperactivity disorder (ADHD). These disorders cause a variety of health problems, including memory loss, deterioration of brain cells, loss of muscle control, and difficulty performing everyday tasks.
To protect against Roundup exposure, it is recommended to use the product in well-ventilated spaces and follow the instructions for proper use on the label.

Ingesting Roundup can cause vomiting, diarrhea, and other immediate symptoms
Roundup is the most commonly used weed killer on farm crops and household lawns in the US. It is a glyphosate-based herbicide that kills weeds by inhibiting plants from producing essential proteins necessary for their growth. The active ingredient in Roundup, glyphosate, is a non-selective herbicide designed to kill most plants it comes into contact with. It targets certain enzymes essential for plant growth.
Because of its potency and toxicity, Monsanto developed genetically engineered crops, known as ready crops, including alfalfa, corn, cotton, and soybeans. These crops are genetically modified to withstand glyphosate. However, glyphosate is also sprayed on non-GMO crops such as wheat, barley, oats, and beans to dry them out for early harvesting. As a result, glyphosate can be found in the food chain, in vegetables and other plants grown in soil previously treated with the herbicide, and in drinking water.
The toxicity of glyphosate has been a subject of debate. While the Environmental Protection Agency (EPA) in the US has stated that glyphosate is unlikely to cause cancer and other negative health effects in humans, other studies, including a 2023 study by the University of California, Berkeley, dispute this claim. The International Agency for Research on Cancer (IARC) has classified glyphosate as a probable human carcinogen, and Roundup as a potentially carcinogenic pesticide.
In addition to cancer, glyphosate has been linked to various health issues, including liver and kidney damage, endocrine and reproductive issues, and neurological disorders. Studies have also found that glyphosate can disturb the healthy bacteria in the gut biome, which plays a vital role in regulating healthy brain functioning. Exposure to glyphosate has been associated with an increased risk of developing neurological disorders such as autism and Alzheimer's disease.

Inhalation of Roundup can irritate the eyes, nose, throat, and lungs
The common herbicide Roundup has been linked to thousands of illnesses and diseases over the past several decades. It contains glyphosate, which is listed on the World Health Organization's (WHO) list of toxic herbicides and pesticides.
Long-term exposure to Roundup can lead to even more severe health concerns. High-level long-term exposure is associated with an increased risk of non-Hodgkin lymphoma and other cancers. Roundup exposure may also increase the risk of neurological disorders, including autism, Alzheimer's disease, Parkinson's disease, and attention deficit hyperactivity disorder (ADHD).
To protect yourself from Roundup exposure, it is important to follow safety guidelines when using the product. This includes using Roundup in well-ventilated spaces, wearing protective gear such as gloves and masks, and following the instructions for proper use on the label.
