Overview

Marler Clark is a Seattle-based law firm that has built a national reputation as 'The Food Safety Law Firm.' Founded in 1993 by attorney William Marler, the firm focuses almost exclusively on representing individuals and families harmed by foodborne illness, including victims of outbreaks linked to E. coli, Salmonella, Listeria, hepatitis A, and norovirus. Over the decades, Marler Clark has been involved in many of the highest-profile food safety cases in the United States, from fast-food hamburger outbreaks to contaminated produce, peanut butter, and pet food. The firm often works on a contingency-fee basis and has recovered hundreds of millions of dollars in settlements and verdicts for clients, according to its public statements. Beyond litigation, Marler Clark operates a family of informational websites—such as Foodborne Illness Outbreak Database, Marler Blog, and various pathogen-specific sites—that track outbreaks and provide consumer education. The firm is frequently cited by national media as an authority on food safety law and outbreak response. Its brand is closely tied to its founder, William Marler, a prominent advocate for food safety reform who has testified before Congress and advised government agencies. Marler Clark remains a private law partnership headquartered in Seattle, Washington, and continues to litigate foodborne illness cases nationwide.

History

Marler Clark was founded in 1993 in Seattle, Washington, by attorney William Marler. The firm initially handled a broad range of personal injury cases, but a landmark 1993 E. coli outbreak linked to Jack in the Box restaurants—which sickened hundreds and killed four children—catapulted Marler into the national spotlight and steered the firm toward a specialized practice in foodborne illness litigation. Marler represented many of the victims in that outbreak, and the case helped establish new standards for food safety in the fast-food industry. Over the following decades, Marler Clark became involved in numerous high-profile outbreaks, including cases involving contaminated spinach, peanut butter, eggs, cantaloupe, and pet food. The firm's attorneys have represented thousands of clients across the United States and have secured settlements and verdicts totaling hundreds of millions of dollars. In addition to litigation, Marler Clark launched a network of informational websites, including the Foodborne Illness Outbreak Database, Marler Blog, and pathogen-specific sites such as About-ecoli.com and About-salmonella.com. These platforms have made the firm a go-to resource for journalists, public health officials, and consumers seeking information on food safety. William Marler has testified before Congress on food safety issues and has been a vocal advocate for stricter regulations. The firm remains a private partnership and continues to operate from its Seattle headquarters, handling cases nationwide.
