Top U.S. retailers such as Home Depot, Target, Walmart and Amazon are sticking by Monsanto’s controversial weedkiller Roundup one week after a California jury awarded a school groundskeeper $289 million for proving the spray caused him to develop non-Hodgkin’s lymphoma.

Since the verdict last Friday, only one UK-based retailer – HomeBase — announced that it will be reviewing the sale of product.

Most big U.S. retailers who sell the product are either staying mum on the issue or following regulations regarding its sale.

In a statement to FOX Business, a Home Depot spokesperson said the company follows all regulatory guidelines regarding the sale of Roundup, and that they plan to continue to sell these products going forward. However, the company will “offer alternative options” for those who have doubts.

Others retailers including Target, Walmart and Amazon declined to comment on the news, but all of them continue to sell the product on their websites.
