Clorox: Pseudomonas Aeruginosa Class Action Alleges Knowing Contamination

• A customer has filed a class action lawsuit against Clorox, alleging the company knowingly sold household cleaners contaminated with *Pseudomonas aeruginosa*.
• The lawsuit follows a September 3 recall of over 6 million bottles of Mistolin and Lestoil multipurpose cleaners due to the dangerous bacterium.
• Plaintiff Leslie Santana claims Clorox had prior knowledge of such contamination, citing a 2022 recall of 37 million Pine-Sol bottles and a $14.15 million civil penalty for failing to report it.
• The action seeks injunctive relief, including mandatory disclosure of risks, improved testing, Spanish language recall notices, and restitution for consumers in Puerto Rico and the U.S. Virgin Islands.

The complaint asserts Clorox knew its scented multisurface cleaners were susceptible to *Pseudomonas aeruginosa*, understood the contamination mechanism in fragranced formulations, knew what testing was required to detect it, and had committed to the federal government to improve its practices.

A customer has initiated a putative class action against Clorox, alleging the company knowingly sold household cleaning products contaminated with a dangerous bacterium. The lawsuit, filed by Leslie Santana, a resident of Puerto Rico, comes after Clorox issued a recall on September 3 for over 6 million bottles of its Mistolin and Lestoil multipurpose cleaners. The recall was prompted by the presence of *Pseudomonas aeruginosa*, a rod-shaped bacterium known to cause serious infections.

This resilient germ can lead to ailments such as pneumonia, rashes, and urinary tract infections, and poses a particular risk to individuals with compromised immune systems or medical devices like catheters, through inhalation, eye contact, or contact with broken skin. Santana's complaint, filed in the U.S. District Court for Northern California, asserts that Clorox was aware of the contamination for an extended period but allowed the products to remain available to consumers.

The products at the center of the *Santana v Clorox lawsuit* were reportedly manufactured between April 1, 2025, and June 17, 2026. They were distributed and sold in Puerto Rico and the U.S. Virgin Islands through major retailers including Walmart, Sam’s Club, Costco, Supermercados Econo, and Supermercados Selectos, with prices ranging from $1.40 to $8.00 per bottle. Santana contends that Clorox marketed and sold these cleaning solutions for 15 months without any warning regarding potential pathogens and permitted them to stay on store shelves for months even after production had ceased.

The current *Clorox Pseudomonas aeruginosa class action* is not the first instance of the company facing allegations related to bacterial contamination in its products. Santana's 35-page complaint highlights a significant prior event from 2022, when Clorox recalled 37 million bottles of scented Pine-Sol due to contamination with the very same bacterium. This earlier incident led to the U.S. Consumer Product Safety Commission (CPSC) charging Clorox with knowingly failing to report the issue promptly, resulting in a $14.15 million civil penalty for the company.

This history forms a critical component of the plaintiff's argument, suggesting that Clorox had direct and extensive experience with *Pseudomonas aeruginosa* contamination. The complaint asserts Clorox knew its scented multisurface cleaners were susceptible to *Pseudomonas aeruginosa*, understood the contamination mechanism in fragranced formulations, knew the necessary testing, and had committed to the federal government to improve its practices. This background underscores the allegations of prior knowledge and alleged negligence in this *product liability class action*.

The *Santana v Clorox lawsuit* brings forth a range of serious legal claims against the multinational household cleaning products manufacturer. These include alleged violations of California’s Unfair Competition Law, California’s False Advertising Law, and California’s Consumers Legal Remedies Act, highlighting the *California consumer protection Clorox* angle. Additionally, the complaint alleges fraudulent concealment, breach of implied warranty against hidden defects, and unjust enrichment.

Santana argues that Clorox had a clear duty to disclose the risks of bacterial contamination, particularly given its prior experiences, and that its failure to address this safety hazard caused material harm. She further contends that the current *Mistolin Lestoil recall* is insufficient to adequately remedy the risks faced by the potential class members. The lawsuit seeks a court order compelling Clorox to disclose the risks of bacterial contamination in its household cleaners, implement and maintain thorough testing and monitoring processes, and provide Spanish language notices of its recalls in Puerto Rico and the U.S. Virgin Islands.

Beyond injunctive relief, Santana also requests restitution and disgorgement of profits. The proposed class could potentially include hundreds of thousands to millions of individuals who purchased the recalled products in Puerto Rico or the U.S. Virgin Islands between April 1, 2025, and the present.

This case underscores the heightened legal and reputational risks for companies with a history of product safety issues, particularly when allegations suggest prior knowledge of contamination. Compliance officers should review internal product testing, recall protocols, and disclosure practices to ensure timely reporting and prevent allegations of fraudulent concealment and consumer protection violations, especially after prior incidents involving similar risks.
