snacks you can trust
We’re committed to providing high-quality snacks you can trust. We adhere to globally recognized SQF food safety standards, and purchase ingredients only from reputable suppliers who conduct testing directly on their soil. Every batch of Puffworks baby is tested for heavy metals by an ISO 17025 accredited third-party lab.
heavy metals
All food, from leafy greens to nuts and whole grains, contains some level of heavy metals as these elements occur naturally in the Earth’s crust. Crops, like peanuts, absorb nutrients from the soil, and along with them trace amounts of heavy metals. While some elements, like iron, are vital for our health, excessive amounts of heavy metals can be harmful - particularly to babies’ growing bodies. The best way to protect your little one? Focus on a balanced, nutrient-rich diet that includes an array of different vegetables, fruits, nuts, lean proteins, and grains.
our standards
While it’s impossible to fully eliminate your baby’s exposure to heavy metals, it’s important to limit their exposure. We are committed to the FDA’s Closer to Zero initiative without sacrificing the nutrient-dense promise of our products. Because federal regulations are limited, especially for grain-based snacks, we will continue to follow our strict internal standards inspired by other leading progressive regulations, including the European Union and ensure that our finished products fall below the Maximum Allowable Dose Levels (MADLs) established by California Proposition 65.

FAQs
Heavy metals such as arsenic, lead, mercury, and cadmium are naturally occurring elements found in the Earth’s crust. Soil that has been contaminated by industrial pollution and some pesticides and fertilizers can contain elevated levels of these elements. While some elements, like iron, are vital for our health, excessive amounts of heavy metals can be harmful - particularly to babies and young children, whose developing bodies are more vulnerable to their toxic effects.
Crops absorb both essential nutrients (like calcium) and harmful metals from the surrounding environment. As a result, all food, including organic or homemade, inevitably contains some amount of heavy metals. Certain nutrient-dense foods — think root vegetables, leafy greens, peanuts and seeds — are grown in the ground, where they’re directly exposed to these environmental contaminants.
The American Academy of Pediatrics
(AAP) recommends babies eat a varied diet, as it’s best for a child’s overall nutrition and it will reduce the chance of a baby consuming a higher concentration of heavy metals from any one source.
Parts per billion (ppb) is a way to measure the concentration of a substance. Think of it like this: 1 ppb is equivalent to a single drop of water in an Olympic-sized swimming pool.
California Assembly Bill 899 requires the use of an ISO accredited lab with the ability to quantify results down to 6 ppb. Test results lower than this level are reported as ≤ 6 ppb; results above this level reflect quantified amount.
California Assembly Bill 899 (AB 899) requires baby food manufacturers to test for heavy metals—arsenic, cadmium, lead, and mercury — and publish the results for all products made after January 1, 2025.
Maryland has passed a similar law called Rudy’s Law, which will take effect in 2026. While these laws are specific to two states, they’re setting the stage for increased safety and transparency nationwide.
California Proposition 65 Safe Harbor Levels or Prop 65, is a California law that ensures consumers are informed if a product contains any substance on its chemical list above safe levels. For heavy metals, Prop 65 standards are based on the Maximum Allowable Dose Level (MADL)- the maximum daily amount considered safe. Because federal limits for baby foods are still in development, Prop 65 has become a key standard for many manufacturers. It’s considered one of the most protective benchmarks in the country.
Yes. Starting this year we are rolling out QR codes on our new Puffworks baby packaging that will allow our customers to review our heavy metals test results on our website. Anyone can access those results by scanning a QR code on the baby food label with their smartphones.
