What’s New for Dangerous Product Lawsuits in December 2025
Even as 2025 comes to a close, some of the most significant dangerous product lawsuits in the country remain active and busy. From the Supreme Court receiving support for potential involvement in the Roundup litigation to a major city entering the ultra-processed food litigation, here are some of the biggest updates among these cases from the last few weeks.
Roundup Lawsuits
It has been a pivotal few weeks for the Roundup lawsuits as tens of thousands of cases remain pending across both federal and state courts.
Last week, the Trump Administration essentially gave the green light for the U.S. Supreme Court to review a Roundup case, siding with Bayer on the company’s claims that these lawsuits are preempted, or overruled, by federal law.
Lower courts have been divided on this issue, but a favorable ruling from the Supreme Court is something that Bayer has been heavily pursuing. The Court will still need to agree to take up the case.
Last month, Bayer also settled a case that won more than $2 billion from a jury verdict in Georgia earlier this year. In a separate Roundup case, a California appeals court upheld a previous $28 million win for a plaintiff.
Talcum Powder Lawsuits
With more than 67,000 active cases in federal court, the talcum powder lawsuits remain the largest consolidated litigation in the country. Major growth has continued for these cases that claim the use of Johnson & Johnson baby powder is tied to ovarian cancer. More than 400 new cases joined the federal litigation last month.
The critical ovarian cancer bellwether trial taking place in California state court is still underway. This trial began last month. Past trials have lasted weeks, so it’s unclear exactly when we will get a verdict. Its outcome could be important for thousands of cases, as the result helps both sides get a better sense of the strength of their arguments.
The bellwether process is also advancing at the federal level, with a final pretrial conference held last month.
Ultra-Processed Foods Lawsuits
There has been little movement among potential ultra-processed foods lawsuits after the landmark case in this litigation was dismissed in August. We’re still waiting to see if a judge will allow that case to be revived with modifications.
But in the interim, a city has taken up the cause. Earlier this month, San Francisco announced that it was suing the makers of ultra-processed foods over costs the city has incurred treating conditions that it says are caused by consumption of these products.
“These companies created a public health crisis with the engineering and marketing of ultra-processed foods,” San Francisco City Attorney David Chiu said in a release. “They took food and made it unrecognizable and harmful to the human body.”
