HHS, FDA Announce Chemical Contaminants Transparency Tool for Foods

SILVER SPRING, Md., March 20, 2025 /PRNewswire/ -- Today, under the leadership of U.S. Department of Health and Human Services Secretary Robert F. Kennedy, Jr., the U.S. Food and Drug Administration unveiled the Chemical Contaminants Transparency Tool (CCT Tool), an online searchable database providing a consolidated list of contaminant levels (e.g., tolerances, action levels, and guidance levels) that are used to evaluate potential health risks of contaminants in human foods. Chemical contaminants include a broad range of chemical substances that may be present in food and that have the potential to cause harm.

"HHS is committed to radical transparency to give Americans authentic, informed consent about what they are eating," said Secretary Kennedy. "This new Chemical Contaminants Transparency Tool is a critical step for industry to Make America Healthy Again."

To protect public health and help industry market products that are safe for U.S. consumers, the FDA establishes or utilizes tolerances, action levels and guidance levels for some contaminants in food. These are levels above which the agency may find that a food may be unsafe but do not represent permissible levels of contamination. The FDA uses these levels to help minimize or prevent chemical hazards in food. 

"Ideally there would be no contaminants in our food supply, but chemical contaminants may occur in food when they are present in the growing, storage or processing environments," said Acting FDA Commissioner Sara Brenner, M.D., M.P.H. "Because many of the most nutritious foods can also contain contaminants, consumers should eat a variety of nutrient-dense foods across and within the main food groups of vegetables, fruits, grains, dairy and protein to help protect from possible exposure effects."

The CCT Tool, which provides contaminant levels in one location for ease of searching, is one of the outcomes of the FDA's initiative to modernize food chemical safety. The consolidated list includes the contaminant name, commodity, contaminant level type (e.g., action level, guidance level), level value and reference (e.g., Code of Federal Regulations, FDA Guidance for Industry). The list can also be filtered by contaminant type.  

The FDA will continue to monitor the food supply by testing foods through several different programs. Under Secretary Kennedy's leadership, the FDA is committed to promoting radical transparency to make sure all Americans know what is in their food and Make America Healthy Again.
