This U.S. House Subcommittee staff report investigated the prevalence and oversight of toxic heavy metals in baby foods sold in the United States. Using data collected from manufacturers, internal company documents, and third-party laboratory test results—including those from Alaska’s State Environmental Health Laboratory—the report critically examined both the levels of heavy metals found in finished baby food products and the industry’s prevailing testing practices. The investigation also evaluated company responses to contamination findings, regulatory gaps, and the adequacy of current and proposed federal standards for arsenic, lead, cadmium, and mercury in baby foods. The focus keyphrase for this review is “heavy metal certification program,” as the document’s findings directly inform the standards, testing, and regulatory requirements that should underpin such a program.
Who was studied?
The report focused on baby food products manufactured by leading U.S. companies: Beech-Nut, Gerber, Plum Organics (Campbell), Walmart (private label), Hain Celestial (Earth’s Best Organic), Nurture (Happy Family Organics/HappyBABY), and Sprout Foods. The study assessed not only the products found on retail shelves—via random sampling and laboratory analysis—but also scrutinized the internal quality assurance and testing policies of these manufacturers. The consumer population most affected are infants and young children who consume these products, a group highly vulnerable to the neurotoxic effects of heavy metals. In addition, the report reviewed the role of federal and state regulators, with particular attention to the FDA’s evolving standards and oversight mechanisms.
Most important findings
| Critical Points | Details |
|---|---|
| Widespread heavy metal contamination | Despite clear violations, recalls were often incomplete. Beech-Nut recalled only some products after state findings, but left others on shelves. Gerber, with similar arsenic levels, recalled nothing. Walmart abandoned its stricter arsenic threshold (23 ppb) in 2018, raising its internal limit to the FDA’s 100 ppb. |
| Inadequate industry testing practices | Most companies test only raw ingredients—not finished products—for heavy metals, leading to systematic underestimation of actual contamination. Hain’s finished product tests showed 28–93% higher heavy metal levels than ingredient-based estimates. Sprout’s policy is especially lax, requiring only annual supplier tests. |
| Regulatory and recall failures | Despite clear violations, recalls were often incomplete. Beech-Nut recalled only some products after state findings but left others on shelves. Gerber, with similar arsenic levels, recalled nothing. Walmart abandoned its stricter arsenic threshold (23 ppb) in 2018, raising its internal limit to the FDA’s 100 ppb. |
| Deficient federal standards and slow regulatory action | The FDA’s current limits focus on cancer risk, not neurological harm, and its action plans to tighten standards are too slow. The Subcommittee called for more protective and immediate limits: 10–15 ppb inorganic arsenic, 5 ppb lead, and 5 ppb cadmium in baby foods—levels already feasible for industry compliance. |
| Recommendations for a heavy metal certification program | The report urges that all baby food manufacturers conduct and report finished product testing, not just ingredient testing. It also recommends proactive phase-out of high-risk ingredients like rice and calls for both regulatory mandates and voluntary industry action to safeguard children’s health. |
Key implications
For a heavy metal certification program, this report highlights the necessity of mandatory finished product testing, transparent data reporting, and strict adherence to substantially lower permissible heavy metal limits. Certification standards must exceed current FDA requirements to truly protect infants, requiring independent verification and proactive ingredient management.

Arsenic is a naturally occurring metalloid that ranks first on the ATSDR toxic substances list. Inorganic arsenic contaminates water, rice and consumer products, and exposure is linked to cardiovascular disease, cognitive deficits, low birth weight and cancer. HMTC’s stringent certification applies ALARA principles to protect vulnerable populations.
Lead is a neurotoxic heavy metal with no safe exposure level. It contaminates food, consumer goods and drinking water, causing cognitive deficits, birth defects and cardiovascular disease. HMTC’s rigorous lead testing applies ALARA principles to protect infants and consumers and to prepare brands for tightening regulations.
Cadmium is a persistent heavy metal that accumulates in kidneys and bones. Dietary sources include cereals, cocoa, shellfish and vegetables, while smokers and industrial workers receive higher exposures. Studies link cadmium to kidney dysfunction, bone fractures and cancer.
Mercury (Hg) is a neurotoxic heavy metal found in various consumer products and environmental sources, making it a major public health concern. Its regulation is critical to protect vulnerable populations from long-term health effects, such as neurological impairment and cardiovascular disease. The HMTC program ensures that products meet the highest standards for mercury safety.
