Commerce in the United States has always relied on a certain trust between manufacturers of goods, the businesses that sell them and the people who use them. If a maker or seller has engaged in fraud or other deception over the quality or use of their products, they may be legally liable for any damage or injury caused by those items.

Glyphosate, a popular weed killer, has been on the American market for decades now. Many farmers and gardeners swear by the chemical’s ability to eliminate unwanted plants between crops and flowers. The attitude changed slightly six months ago when a groundskeeper became the first to win a lawsuit alleging that glyphosate causes cancer in humans.

Now, a California court is taking the same issue on as it rules on a lawsuit brought by a farmer diagnosed with cancer. His attorney claims that a specific brand of glyphosate included other chemicals that made the main ingredient a stronger carcinogen that caused his non-Hodgkin’s lymphoma. This is the same type of cancer diagnosed in the successful plaintiff from last year.

The current plaintiff claims he has been using the brand of glyphosate for more than 30 years and was diagnosed with cancer in 2015. His suit claims the manufacturer knew the chemical was unsafe, which amounts to insufficient warnings for users at least and malice at worst.

Victims of unsafe or improperly classified products and services may sue for the financial damages required to recover from an injury or illness. An attorney can help judge the evidence against a maker or seller and help a plaintiff push a case forward to a verdict or settlement.
