A Lander man filed a federal lawsuit against agricultural chemical giant Monsanto on Friday, alleging the company’s Roundup weedkiller caused or contributed to his developing non-Hodgkin’s lymphoma.

The suit, filed by Jackson attorney Jason Ochs, joins a recent wave of litigation against Monsanto alleging that Roundup causes cancer. In August, a jury in San Francisco found the weedkiller at least contributed to a former groundskeeper’s diagnosis of non-Hodgkin’s lymphoma. The case was reportedly the first involving Roundup to go to trial, and the jury awarded $289 million to the groundskeeper (that figure has since been reduced by a higher court. Monsanto is also appealing the verdict).

The success of that suit has triggered even more litigation. Reuters wrote in August that Monsanto was facing roughly 8,000 lawsuits related to Roundup. Other media reports place the number closer to 10,000.

In the Wyoming case, Ochs’ client, Jace Florquist, regularly used the weedkiller around his property from 2008 to 2014 and was exposed to it beforehand by his neighbor’s use.
