In 2024, we saw a continued rise in consumer class actions, with contamination cases remaining at the forefront. These lawsuits have hit various consumer industries, including food, household, and personal products. Particular attention continues to focus on PFAS chemicals, a class of synthetic chemicals used in a variety of industrial and consumer products. Although Plaintiffs’ lawyers have been suing over PFAS for years, the earlier litigations were environmental contamination cases. In recent years, as regulations and awareness of PFAS have expanded, so too have the companies and industries targeted and the types of PFAS-related claims asserted. Consumer activists and certain plaintiffs’ law firms have initiated aggressive campaigns to test entire categories of consumer products, apparel, cosmetics, beverages, and food packaging materials for the presence of PFAS and expose the results. Lawsuits have quickly followed. Today, if PFAS are found in a company’s finished product — even in trace amounts and/or as an unintentional consequence of environmental contamination — the company is at risk of litigation.
Typically, plaintiffs allege that a product’s label was false or misleading because the product contains PFAS but was marketed as “all natural,” “safe,” “sustainable,” or “free of toxic chemicals,” among other representations. Many PFAS plaintiffs rely on testing co-opted from third-party sources (e.g., Consumer Reports, bloggers, non-profit organizations), while others conduct independent testing through third-party labs. These testing results may be influenced by contamination during the testing or sampling process or by interference from non-PFAS substances that can mimic a positive PFAS result. The results often suggest that products were subject to inadvertent PFAS contamination during the manufacturing process or afterwards. In fact, many companies faced with this litigation are unaware that their products contain PFAS.
These claims survive motions to dismiss in many cases so far. For example, in a class action alleging that anti-fog spray was marketed as “safe for use” even though it purportedly contained PFAS, the court held that whether a reasonable consumer would interpret those representations as relating to PFAS was a question of fact that could not be resolved at the motion to dismiss stage. Recently, courts are more likely to grant a motion to dismiss for lack of standing if a plaintiffs fail to allege that they tested their own purchases for PFAS, directly.
