FDA Takes Bold Steps to Strengthen Food Safety: Two Major Actions to Reduce Chemical Risks in Your Diet

The U.S. Food and Drug Administration (FDA) has taken two major steps to strengthen food chemical safety, marking a significant shift in how the agency monitors and regulates additives in the American food supply. Effective May 12, 2026, the FDA finalized its Food Chemical Safety Post-Market Assessment Program, a proactive framework designed to systematically evaluate chemicals already in use, and launched a reassessment of two widely used additives: butylated hydroxytoluene (BHT) and azodicarbonamide (ADA). These moves reflect growing public concern over hidden chemicals in processed foods and a broader push by the agency to modernize its approach to food safety oversight.

Dr. Marty Makary, M.D., M.P.H., FDA Commissioner, framed the actions as a response to demand for “rigorous oversight” of food chemicals, emphasizing that the agency will now act “swiftly based on findings.” The new program introduces a structured, science-based process for identifying, prioritizing, and reassessing food chemicals—including those already approved for use. This marks a departure from the FDA’s historical reliance on pre-market approvals, instead adopting a more dynamic, post-market surveillance model similar to those used in pharmaceuticals and medical devices.

But what do these changes mean for consumers, food manufacturers, and public health? And how will the FDA’s new approach impact the safety of everyday products? Below, we break down the key details, explain the science behind the targeted additives, and outline what happens next in this evolving regulatory landscape.

What Is the FDA’s New Food Chemical Safety Program?

The FDA’s Food Chemical Safety Post-Market Assessment Program establishes a proactive, systematic process for monitoring and evaluating chemicals in food after they have entered the market. Unlike traditional regulatory pathways—where chemicals are reviewed before approval—the new program focuses on post-market surveillance, allowing the agency to respond more quickly to emerging safety concerns.

Two key documents underpin the program:

1. Enhanced Systematic Process for Post-Market Assessment of Chemicals in Food: Outlines how the FDA will collect, triage, and evaluate safety signals related to food chemicals. The process includes public engagement opportunities and transparent communication of findings.
2. Post-Market Assessment Prioritization Tool: A risk-based framework to identify which chemicals warrant full scientific assessment, prioritizing those with the highest potential public health risks.

This approach aligns with global trends, including the European Food Safety Authority’s (EFSA) post-market monitoring of food additives. However, the FDA’s program is notable for its explicit focus on public feedback and annual reassessment cycles, ensuring continuous oversight rather than one-time approvals.

Why Now? The Push for Stricter Oversight

Public scrutiny of food additives has intensified in recent years, driven by:

• Consumer advocacy: Groups like the Center for Food Safety and Environmental Working Group (EWG) have long called for stricter regulations on chemicals linked to health risks, including endocrine disruption and carcinogenicity.
• Scientific advancements: Improved analytical techniques now allow detection of trace chemicals in food at previously undetectable levels, raising questions about long-term exposure.
• Regulatory gaps: The FDA’s current system relies on industry self-reporting for many additives, with limited mandatory testing requirements for post-market safety.

The new program also reflects broader FDA priorities under Commissioner Makary’s tenure, including:

• Accelerating biosimilars and gene therapies.
• Modernizing infant formula regulations.
• Reassessing artificial food dyes and ultra-processed foods.

Two Additives Under the Microscope: BHT and ADA

As part of its first major action under the new program, the FDA launched reassessments of butylated hydroxytoluene (BHT) and azodicarbonamide (ADA), two chemicals with long histories in food production but growing safety concerns.

1. Butylated Hydroxytoluene (BHT)

BHT is a synthetic antioxidant added to foods to prevent spoilage, particularly in fats and oils. It is commonly found in:

• Processed snacks (e.g., potato chips, crackers).
• Packaged foods (e.g., cereals, gum, dried fruits).
• Cosmetics and pharmaceuticals.

While BHT has been deemed Generally Recognized as Safe (GRAS) by the FDA since 1959, recent studies have raised questions about its potential health effects, including:

• Hormonal disruption: Animal studies suggest BHT may interfere with thyroid function and reproductive hormones.
• Neurotoxicity: Some research links BHT exposure to behavioral changes in animal models.
• Carcinogenicity: The International Agency for Research on Cancer (IARC) classifies BHT as a possible human carcinogen (Group 2B), though human data remain limited.

The FDA’s reassessment will evaluate:

• Current exposure levels in the U.S. Diet.
• New toxicological data since the last review (1982).
• Alternative antioxidants with lower risk profiles.

2. Azodicarbonamide (ADA)

ADA is a bleaching agent and dough conditioner used primarily in:

• Bread and baked goods.
• Rubber products (including some food packaging).

ADA has faced scrutiny due to:

• Allergic reactions: Some individuals experience respiratory symptoms or skin irritation upon exposure.
• Potential carcinogenicity: ADA breaks down into semicarbazide, a compound classified as a possible human carcinogen by the IARC.
• Mislabeling risks: ADA has been found in counterfeit meat products (e.g., “yellow water” scandals in Asia), where it is used illegally to mimic freshness.

The FDA’s reassessment will focus on:

• Residue levels in food after processing.
• Consumer exposure via inhalation (e.g., from flour dust in baking).
• Alternatives such as ascorbic acid (vitamin C) for dough conditioning.

How Will the FDA’s New Program Work in Practice?

The agency’s approach involves three key phases:

1. Signal Detection

The FDA will monitor for “safety signals” from:

• Public reports: Adverse event databases (e.g., FDA’s MedWatch).
• Scientific literature: Peer-reviewed studies on chemical toxicity.
• Industry data: Voluntary submissions from manufacturers.

2. Prioritization

Using its Post-Market Assessment Prioritization Tool, the FDA will rank chemicals based on:

• Potential for harm (e.g., carcinogenicity, endocrine disruption).
• Exposure levels in the population.
• Availability of safer alternatives.

3. Action and Communication

For high-priority chemicals, the FDA will:

• Conduct full risk assessments.
• Issue public advisories if risks are identified.
• Propose regulatory changes, including restrictions or bans.

Critically, the program includes public engagement at every stage, allowing stakeholders—including consumers, scientists, and industry—to submit data or concerns.

Who Is Affected by These Changes?

The FDA’s actions will impact multiple groups:

Consumers

While the program aims to increase transparency, immediate changes to food labels or product availability are unlikely. However, long-term benefits may include:

• Reduced exposure to controversial additives.
• Greater access to information about chemical safety.
• Potential shifts toward natural preservatives (e.g., rosemary extract, vitamin E).

Food Manufacturers

Companies using BHT or ADA may face:

• Increased scrutiny of supply chains and testing protocols.
• Higher costs if alternatives must be adopted.
• Reputational risks if products contain additives under reassessment.

Public Health Advocates

Groups pushing for stricter regulations, such as the EWG’s Food Additives Database, see the program as a step forward but warn that:

• Industry self-regulation remains a loophole.
• Some chemicals (e.g., titanium dioxide) still lack adequate safety reviews.

What Happens Next? The Timeline for Reassessment

The FDA has not set firm deadlines for the BHT and ADA reassessments, but the agency’s annual post-market assessment plan suggests a structured timeline:

Next Official Update: The FDA will publish its first annual report on the post-market assessment program by May 2027, detailing progress on BHT, ADA, and other prioritized chemicals. Consumers can track developments via the FDA’s Food Additives Petitions page.

Key Takeaways: What You Need to Know

• The FDA’s new program shifts from pre-market approvals to post-market surveillance, allowing faster responses to emerging risks.
• BHT and ADA are the first additives under reassessment, but more chemicals may follow if safety signals emerge.
• Public input is central: Consumers can submit concerns via the FDA’s contact form or through petitions.
• No immediate bans are expected, but manufacturers may voluntarily phase out controversial additives to avoid regulatory action.
• Long-term benefits could include safer food choices, though alternatives may not be perfect (e.g., natural preservatives can also pose risks).

How Can You Stay Informed?

To follow the FDA’s food chemical safety initiatives:

• Subscribe to the FDA’s email alerts for food safety updates.
• Monitor the FDA’s Food Additives Database for petitions and rulings.
