Mass Tort Litigation Cases to Watch in 2025
2025 will see a series of mass tort cases involving PFAS chemicals, social media platforms, Bayer’s Roundup, preterm infant formula, and emerging litigation against ultra-processed food companies. The legal battles highlight concerns over product safety and corporate accountability.

Mass tort litigation is set to make headlines in 2025 with a series of high-profile cases and evolving legal theories. Key issues include PFAS, the so-called ‘forever chemicals’ found in firefighting foam, which continue to be at the center of personal injury claims predominantly in South Carolina. Major players are also in the spotlight, with lawsuits targeting social media giants like Meta and TikTok for alleged impacts on teen mental health, as trials are scheduled to begin in October 2025.
Bayer’s ongoing litigation over Roundup, where the glyphosate ingredient is claimed to cause cancer, remains in focus despite the shadow of previous massive verdicts. Additionally, nearly 1,000 pending cases allege that preterm infant formula from Abbott and Mead Johnson has contributed to necrotizing enterocolitis. A nascent yet potentially transformative case against ultra-processed food companies, which accuses them of marketing harmful products, may also set the stage for future litigation trends. Notable reports on these trends were published by Reuters (December 23, 2024, and December 10, 2024), Mass Tort Beat (late January and early February 2025), and Economic Times LegalWorld (December 24, 2024).
