Andrew Do is an associate in the firm’s Chambers top-ranked Food, Drug, and Device Practice Group. Andrew draws on his scientific training, years at FDA, and experience on political campaigns to provide strategic advice to clients on a broad range of regulatory compliance and policy issues. He works at the intersection of law, policy, and politics to help clients navigate complex matters.

He has assisted companies, trade associations, and private equity clients on a myriad of matters, including in complying with FDA regulations, assessing regulatory and consumer litigation risks, responding to FDA enforcement actions and Congressional inquiries, analyzing proposed bills and legislative priorities on Capitol Hill, and conducting due diligences of FDA regulated companies for acquisition.

Before joining Covington, Andrew was an ORISE Research Fellow with the Center for Food Safety and Applied Nutrition (CFSAN) at FDA, where he conducted research on food allergens, gluten, and pathogens to support the agency’s regulation and enforcement concerning food products. His research and work have been published in numerous scientific peer-reviewed journals.

On May 16, 2023, FDA released a draft compliance policy guide (“draft CPG”) for major food allergen labeling and cross-contact, which updates the 2005 CPG Sec 555.250 Statement of Policy for Labeling and Preventing Cross-contact of Common Food Allergens. CPGs are intended to advise FDA staff, including investigators, of the agency’s strategy for assessing and enforcing industry compliance. The draft CPG contains FDA’s current policies on major food allergen labeling requirements, allergen cross-contact, voluntary allergen information (e.g., advisory label statements), thresholds, and regulatory actions. The draft CPG is more comprehensive than the 2005 CPG and is intended to create a uniform standard and minimize the possibility that individual FDA staff will follow differing regulatory approaches.    

The draft CPG details the allergen labeling requirements of the Federal Food, Drug, and Cosmetic Act. We do not discuss those requirements here, but instead focus on the policies the draft CPG discusses that are not addressed, in detail, in other FDA allergen documents, such as the recent draft guidance, Questions and Answers Regarding Food Allergens, Including the Food Allergen Labeling Requirements of the Federal Food, Drug, and Cosmetic Act.

I. Allergen Cross-Contact

Allergen cross-contact is the unintentional incorporation of a food allergen into a food that does not contain that allergen as an ingredient. The draft CPG notes that the likelihood an allergen will be present due to cross-contact can be impacted by factors such as the characteristics of the food, the distribution of the allergen within a food (homogeneous versus particulate), the type of manufacturing process, the equipment used, and the cleaning procedures applied (e.g., dry cleaning versus wet cleaning). While FDA acknowledges these factors, the agency states that cross-contact may occur due to practices such as the failure to clean shared equipment adequately or segregate allergens properly, improper rework addition, or improper production scheduling. The draft CPG does not explicitly acknowledge that even with adequate CGMPs, sanitation, and preventive controls, cross-contact can still occur.

The draft CPG also confirms FDA’s position that “[m]ajor food allergens unintentionally incorporated into a food are not to be declared in the ingredient list or the ‘Contains’ statement.”Continue Reading FDA Issues Draft Compliance Policy Guide for Major Food Allergen Labeling and Cross-Contact

On January 31, 2023, FDA Commissioner Robert M. Califf announced a proposed redesign of the human foods program at FDA. The proposal follows the findings and recommendations of a Reagan-Udall Foundation expert panel that Dr. Califf had charged with evaluating the agency’s existing human foods program. Commissioner Califf called the redesign “transformative” and believes the
