Bayer AG’s Monsanto unit must pay $185 million to three teachers who blamed their brain injuries on exposure to the company’s PCBs at a school in Washington state.

A state jury in Seattle awarded $50,150,000 in actual damages, and $135 million in punitive damages to the teachers following a six-week trial, which was broadcast by Courtroom View Network. The jury deliberated 1 1/2 days before reaching the verdict Tuesday afternoon.

The teachers claimed they were exposed to PCBs from fluorescent lighting in the Sky Valley Education Center in Monroe, Washington, and caulk used in its walls. They claimed the Snohomish Health District knew of the presence of PCBs at the school long before it took remedial action

Bayer said it disagreed with the jury’s verdict and plans to appeal, if necessary.

“The undisputed evidence in this case does not support the conclusions that plaintiffs were exposed to unsafe levels of PCBs at the Sky Valley Education Center (SVEC) or that any exposure could have possibly caused their claimed injuries,” Bayer said in an emailed statement. “In reality, testing reflected extremely low levels of PCBs in this school.”
