Glyphosate, the main ingredient in Roundup, has been linked to an increased risk of non-Hodgkin lymphoma.
The reputation of Roundup, whose active ingredient is the world’s most widely used weed killer, took a hit on Tuesday when a federal court unsealed documents raising questions about its safety and the research practices of its manufacturer, the chemical giant Monsanto.
Roundup and similar products are used around the world on everything from row crops to home gardens. It is Monsanto’s flagship product, and industry-funded research has long found it to be relatively safe. A case in federal court in San Francisco has challenged that conclusion, building on the findings of an international panel that claimed Roundup’s main ingredient might cause cancer.

FRESNO, Calif. (AP) — Regulators in California took a pivotal step on Monday toward becoming the first state to require the popular weed killer Roundup to come with a label warning that it's known to cause cancer.
Officials announced that starting July 7 the weed killer's main ingredient, glyphosate, will appear on a list California keeps of potentially cancerous chemicals. A year later, the listing could come with warning labels on the product, officials said.
Naperville Park District has suspended the application of chemical weed killer on playgrounds in response to a petition questioning the district's weed control efforts in parks.
Executive Director Ray McGury said the park district acknowledged public health and safety supersede any other concern so the district agreed to stop applying Montanto's Roundup brand of the herbicide glyphosate in playground areas in order to experiment with and evaluate organic weed control products the rest of the summer.
A group of environmental health researchers is calling for federal regulators to reassess the safety of the world's most commonly used herbicide following a series of news stories damaging to the chemical's manufacturer.
The researchers writing in the Journal of Epidemiology and Community Health argue that the chemical glyphosate, sold around the world as Roundup by Monsanto, should be subject to further safety review about whether it causes cancer. U.S. and European regulators have determined that it likely does not, while a United Nations body has found that it likely does.
