The FDA tested more than 300 infant formula products for heavy metals, PFAS, pesticides, and other contaminants. What does it mean for safety? In this post, we explore the safety of infant formula.
But the most important takeaway from the report is straightforward:
The FDA confirms the infant formula products tested are safe for infants.
Top Takeaways:
- The FDA recently released testing results for infant formula products sold in the United States and reported no safety concerns.
- Testing included more than 300 samples of infant formula from major manufacturers.
- The FDA found contaminant levels either non-detectable or at very low levels consistent with existing safety standards and environmental background exposure.
- Infant formula remains one of the most highly regulated food products in the United States.
- Experts continue to advise against homemade infant formula because commercially prepared formula is specifically designed to meet infants’ nutritional needs.
What contaminants did the FDA test for in the infant formula?
The FDA’s testing included screening for contaminants, including:
- arsenic
- cadmium
- lead
- mercury
- pesticides
- PFAS
- phthalates
The agency reported that most results were either non-detectable or present at extremely low levels. Importantly, the FDA stated that the levels observed did not raise health concerns based on current scientific evidence and exposure assessments.
This kind of monitoring is a normal and expected part of modern food safety oversight.
What did the FDA actually find in infant formula? What do those numbers mean in real terms?
The FDA tested more than 300 infant formula samples and generated over 120,000 data points.
The results showed that an overwhelming majority of infant formula products had either:
- no detectable contaminants, or
- very low levels well below existing EPA drinking water requirements.
Here’s what the FDA found when formulas were tested as prepared for feeding:
Arsenic
- 48% of samples had no detectable arsenic
- 42% contained between 0.6–2.0 parts per billion (ppb)
- 6% contained detectable levels up to 0.5 ppb
- 4% were above 2.0 ppb
All samples were at least 2x below the EPA drinking water requirements for arsenic.
Cadmium
- 34% had no detectable cadmium
- 19% contained up to 0.2 ppb
- 44% contained between 0.3–1.1 ppb
- 3% were above 1.1 ppb
All samples were at least 3x below the EPA drinking water requirements for cadmium.
Lead
- 40% had no detectable lead
- 37% contained between 0.3–0.5 ppb
- 20% contained up to 0.2 ppb
- 3% were above 0.5 ppb
All samples were at least 8x below the EPA drinking water requirements for lead.
Mercury
- 95% of samples had no detectable mercury
- 5% contained detectable mercury up to 0.3 ppb
All samples were at least 6x below the EPA drinking water requirements for mercury.
The FDA also reported:
- No pesticides were detected in 99% of samples
- There were no detections for 25 of the 30 PFAS compounds tested
- 95% of samples had PFAS levels at or below 28 parts per trillion (ppt)
- 95% of samples had phthalate levels at or below 116 ppb
These are extremely small quantities.
A part per billion is one second in nearly 32 years or one drop of water in an Olympic-sized swimming pool.
A part per trillion is even smaller and is roughly equivalent to one second in nearly 32,000 years.
The FDA specifically noted that all tested samples were significantly below EPA drinking water requirements for lead, mercury, cadmium, and arsenic.
That means the levels identified were not considered a safety concern based on current scientific standards and exposure assessments.
It is also important to remember that these substances are naturally present in the environment. Trace amounts can be found throughout the food supply because they exist in soil, water, and air. Modern laboratory instruments are simply capable of detecting extraordinarily tiny amounts.
The FDA’s findings reinforce that commercially available infant formula in the United States remains highly monitored, highly regulated, and safe for consumers.
Why are there trace contaminant levels in infant formula?
Heavy metals and similar contaminants are naturally present in the environment. They can occur in soil, water, and air, meaning trace amounts may appear in many foods, including fruits, vegetables, and grains that make their way into finished products.
It’s important to remember that the presence of a detectable substance does not automatically mean a product is unsafe. Modern laboratory equipment is capable of detecting incredibly small amounts of substances, often at parts per billion or lower. That sensitivity is actually a sign of how advanced food safety testing has become, not that there is any harm in what’s detected.
Is infant formula highly regulated for safety?
Infant formula is one of the most carefully regulated food categories in the United States. Commercial formulas must meet strict federal nutritional standards designed to support infant growth and development.
Additionally, manufacturers are required to follow rigorous production, testing, and quality control requirements before products reach store shelves.
The FDA also continues to monitor products after they enter the market through routine surveillance and targeted testing programs. The latest results indicate that the ongoing oversight system is in place.
Why do experts continue to recommend commercial infant formula?
During the infant formula shortage in 2022, homemade formula recipes spread widely online. Many were promoted as “natural” alternatives to commercial products.
However, medical experts and regulatory agencies continue to advise against homemade infant formula because infant nutrition requires extremely precise nutrient balances that cannot be safely replicated in a home kitchen.
Commercial formulas are specifically designed and tested to ensure infants receive appropriate levels of vitamins, minerals, fats, proteins, and carbohydrates needed for healthy development.
Homemade formulas may unintentionally contain unsafe nutrient imbalances or contamination risks.
For families using formula, commercially prepared products remain the safest and most reliable option.
What should parents take away from the FDA results?
Infant formula remains safe for infants when prepared and used as recommended.
The good news.
The FDA’s results show that infant formula remains safe. It also shows that ongoing testing, scientific review, and regulatory oversight are working to ensure infant formula remains safe and meets the nutritional needs of our most vulnerable.
