Miriam Guggenheim, co-chair of Covington’s Food, Drug and Device Practice Group, assists a broad range of major food and dietary supplement companies in achieving their marketing goals while minimizing regulatory and litigation risks. She also helps clients successfully navigate crises such as recalls and unwanted Congressional or regulatory attention. In addition to her work for individual clients, Miriam serves as outside counsel to a number of key trade associations, helping them accomplish broad industry objectives by engaging with the FDA, FTC, and Congress. Chambers USA notes, Miriam is "incredibly sharp and very responsive" and a client reports, "I rely on Miriam tremendously to help me find ways forward in difficult and novel situations, and she never fails to deliver."

As the food industry faces new challenges – including scrutiny of ingredients and food packaging materials, concerns about heavy metals and other contaminants, attention to “ultra-processed foods,” and increasing consumer fraud litigation and Prop 65 demand letters – Miriam remains at the forefront of legislative and regulatory changes and food policy and litigation trends. She draws on this deep knowledge and insight to advise clients on all aspects of food development and marketing, from product ingredient sourcing and manufacturing considerations to food labeling and marketing. Partnering with Covington colleagues in international offices, Miriam helps clients solve regulatory problems across the globe.

Yesterday, Texas governor Greg Abbott signed into law S.B. 25, which requires food products containing any of 40+ specified ingredients to bear a warning label. This follows Texas’s enactment of S.B. 314 in late May, which prohibits Texas school districts and open-enrollment charter schools from providing free or reduced-price meals that contain any of 17+ specified ingredients. As of the date of this writing, Louisiana S.B. 14, which would impose (1) disclosure requirements for any food product sold in the state that contains specified ingredients, and (2) a ban on the use of certain ingredients in school meals, is sitting on the governor’s desk. It will become law if he signs it or takes no action by June 25. These actions are part of a larger trend of increased scrutiny of food and color additives, as we previously reported and which is a significant feature of the Make America Healthy Again (“MAHA”) Commission’s Assessment released on May 22, 2025.

Texas S.B. 25

S.B. 25 requires human food products containing any of 40+ specified ingredients to bear the following warning label: “WARNING: This product contains an ingredient that is not recommended for human consumption by the appropriate authority in Australia, Canada, the European Union, or the United Kingdom.” Violators may be subject to a fine not to exceed $50,000 per day for each distinct food product in violation of the requirement.

The ingredients subject to the warning label requirement are the FD&C colors (i.e., Blue Dye No. 1, Red Dye No. 40, etc.) and numerous other ingredients including bleached flour, bromated flour, azodicarbonamide, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), potassium bromate, and propylparaben. Although the sweeteners aspartame, sucralose, acesulfame potassium (as well as high fructose corn syrup) were listed in earlier drafts of the bill, they are not included in the bill ultimately signed into law. 

The warning requirement will apply only to food product labels “developed or copyrighted on or after January 1, 2027.” Thus, it appears that food labels in use or even just copyrighted before that date could continue to be used for extended periods of time beyond that date.

On March 24, 2025 Governor Patrick Morrisey of West Virginia signed into law H.B. 2354 which will impose a ban on the use of specified food additives, including seven food dyes, in food, drink, confectionery, or condiment products in the state. In passing this law, West Virginia became the first state…
