CLEVELAND, Ohio (WOIO) - The debate over the safety of Roundup weedkiller continues after a jury ordered Bayer to pay more than $2 billion in damages to a California couple that claimed they got cancer from using the weedkiller for years.

This comes two weeks after the EPA said Roundup’s active ingredient, glyphosate, does not cause cancer.

But the cancer research agency of the World Health Organization called glyphosate "probably carcinogenic."

Watch our full story on concerns over Roundup and weedkillers here.

We checked in with 15 school districts across Northeast Ohio to see what pesticides or organic alternatives they are using.

19 News asked what product or brand they use on school grounds, how much of it they use and how often.

We also asked if children are kept off the grass and whether parents are notified.

Only eight school systems replied to our questions.

Cleveland, Shaker Heights, Beachwood, Parma, Chardon, Ashtabula and Sandusky school districts did not reply.

Here are the results by school district.


The school district did not answer our questionnaire. They sent us the statement below, adding they are considering organic alternatives after we asked them to specify.

“The Avon Local School district is currently evaluating alternatives to treatments on our school grounds. We have not purchased Roundup this year. As we continue to test products, and evaluate the effectiveness of those products, as well as cost of the products, we will make a determination regarding future product purchases after our evaluations.”
