Mitzi Ng Clark: Attorney with Keller and Heckman LLP

Biography

Mitzi Clark advises domestic and international corporations on a wide range of food, cosmetic, and drug packaging regulatory issues, ranging from U.S. Food and Drug Administration (FDA) premarket clearance requirements for food contact materials and local and state regulations concerning plastics and chemicals, to good manufacturing issues and regulatory requirements for food, alcoholic beverages, cosmetics, and animal feed. Mitzi’s practice extends to the international arena, where she regularly counsels clients on regulatory matters in jurisdictions such as Asia, Canada, the European Union (EU), Latin America, Africa, and the Middle East.

Mitzi began her legal career at Keller and Heckman in the firm’s Washington, DC office where she experienced firsthand the mechanics of U.S. regulatory agencies. Recognizing the need for food contact expertise on the West Coast, she relocated in 2018 to Keller and Heckman’s San Francisco office, which she currently manages. Since her time in San Francisco, Mitzi has helped numerous companies understand the nuances of various state and local laws and regulations, including California’s Proposition 65, A.B. 1200 on Plant-Based Food Packaging and Cookware, the Plastic Pollution Prevention and Packaging Producer Responsibility Act (SB 54), the Rigid Plastic Packaging and Container Program (RPPC), and the State’s plastic bag legislation.

While in law school, Mitzi served as the executive editor of the Temple Environmental Law and Technology Journal. Before attending law school, Mitzi received a Master's in Public Health. Coupled with her scientific background in cancer research, Mitzi’s experience in public health and epidemiology brings a unique technical perspective to complex regulatory matters.

Mitzi has contributed to various trade publications, including Food Packaging Bulletin, Plastics Recycling Update, and FLEXO Magazine, as well as packaginglaw.com . She is frequently invited to speak at domestic and international conferences and has presented on topics related to food contact regulatory matters, recycled plastics, and California’s Proposition 65 and other state-related legislation.
