Recent peer-reviewed research revealed that California’s Proposition 65 (Prop 65), which regulates toxic chemicals such as PFAS and phthalates commonly found in plastic lunch boxes, food packaging, backpacks and storage cases, has effectively reduced the levels of harmful substances in residents’ bodies.California’s Prop 65, enacted in 1986, requires companies selling products within the state to disclose the presence of chemicals known to cause cancer, birth defects or reproductive harm. The regulation currently encompasses approximately 850 chemicals, including six phthalates identified as potentially risky to health.
