There is a number that has been sitting with me since May 20th. Actually, two numbers. 5,000 and 11,000. The first is the estimated number of microplastic particles in a single Gerber pouch. The second is what an independent lab found in a single Happy Baby Organics pouch. One pouch = one serving. And too many babies and toddlers have more than one pouch at a time...
The report is called Tiny Plastics, Big Problem: The Hidden Risks of Plastic Pouches for Baby Food. Greenpeace commissioned an independent lab - SINTEF Ocean - to test two of the most recognizable baby food brands in America. They found microplastics in every single sample. They also found plastic-associated chemicals in both the packaging and the food itself, including a potential endocrine-disrupting chemical in the Gerber samples. Endocrine disruptors interfere with the body's hormone system - the system that regulates brain development, metabolism, immune function, and reproductive health. In babies, whose hormone systems are still forming, that interference does not always show up right away. It can take years. All of this in a product marketed to parents as safe, convenient nutrition for their babies. Convenient, maybe. Safe, definitely not.
The pouch industry has spent years hiding behind words like "BPA-free," "non-GMO," and "organic." Those labels line shelves worldwide while the format - plastic squeeze pouches - has seen sales skyrocket by approximately 900% between 2010 and 2023. BPA-free does not mean plastic-free. Organic ingredients do not cancel out a plastic lining leaching particles into the food. The label is doing a lot of work to distract from what is actually happening at the molecular level.
What the Study Actually Found
The SINTEF Ocean lab tested Danone's Happy Baby Organics fruit puree and Nestlé's Gerber yogurt puree, both in plastic spouted pouches. For each gram of food, they found up to 99 microplastic particles in the Happy Baby Organics pouches and up to 54 in the Gerber pouches on average. Scale that to a full pouch and you get the numbers above.
The study suggests a link between the type of plastic the pouches are lined with - polyethylene - and some of the microplastics found in the baby food. In other words, the packaging itself is likely the source. The food goes in -> the plastic breaks down -> the particles end up in the purée -> then in the baby.
Dr. Leo Trasande, Director of NYU Grossman School of Medicine's Division of Environmental Pediatrics, is one of the country's leading researchers on plastic exposure in children. His work has repeatedly shown that the period of greatest vulnerability is early life - when organ systems are still forming and exposures have the longest window to cause downstream harm.
Greenpeace Senior Plastics Campaigner Lindsey Jurca said it plainly: "For nearly a century, Gerber has been one of the most trusted names in feeding American babies. That trust has been shattered."
Why Pouches Are the Problem - Not Just the Contents
This is the part that gets lost in the coverage. Parents often assume the issue is what is inside the pouch - the ingredients, the sugar content, the processing. They're focused on heavy metals (which are unavoidable given that they are in our air, soil, and water supplies). The Greenpeace report is about the packaging. The plastic itself is contaminating the food before baby ever squeezes the drinkable mush into their mouths.
Flexible plastic pouches are lined with polyethylene. That lining is in direct contact with the food, often for months on the shelf before it ever reaches a baby. Heat, light, time, and mechanical stress - like squeezing - can all accelerate the breakdown of plastic into particles. By the time the pouch is opened, the damage to the food inside is likely already done.
This is not a fringe concern or an environmental advocacy position. Microplastic particles were found in every sample analyzed. Not some, not most, but every single one.
The "Organic" Problem
Happy Baby Organics is one of the brands named in this report. Parents who buy organic baby food are making an active choice to reduce their child's exposure to pesticides, artificial ingredients, and chemical additives. They are reading labels, and paying more for that choice. They are doing what they think is right.
The organic certification covers what is grown and processed. It does not cover what the packaging does to the food after it is sealed inside. A pouch of organic fruit purée with 11,000 microplastic particles in it is not the product the parent thought they were buying. The label is telling one story while the contents are telling another.
This is the kind of gap that does not get closed by better ingredient sourcing. It requires a different container entirely.
Glass Was Never Just About Aesthetics
Globowl uses glass jars. We made that decision before the Greenpeace report came out, before the microplastics conversation reached mainstream parenting media, before any of this was a marketing talking point. We made it because glass is inert. It does not leach. It does not interact with the food inside. What goes into the jar stays exactly as it is - no plastic particles, no chemical migration, no invisible contamination traveling from packaging to purée. A safe environment for the must vulnerable among us!
Glass is also the format parents can actually see through. You know what you are getting before the jar is even opened. At Globowl, that transparency is not an accident - it was all strategically and heart-fully chosen so that parents could feel safe. (You should see the reports on what's been found inside colored plastic pouches that unassuming parents and babies never saw coming!)
The pouch became dominant because it is convenient. Easy to throw in a diaper bag, easy for a baby to hold, easy for a parent to hand over without utensils. Convenience is real and valid. But convenience built on a container that may be contaminating the food it holds is a trade-off most parents were never given the chance to make - because they did not know the trade-off even existed.
Now they do, and....the more you know!
What Parents Should Do With This Information
First: do not panic about what has already been consumed. The science on long-term health outcomes from microplastic exposure in infants is still developing. What the Greenpeace report establishes is presence and source - not a definitive harm threshold.
It also reports that continued, daily exposure through a primary food format is not a reasonable risk to accept when alternatives exist. Especially during the period of greatest developmental vulnerability, which is exactly when babies are eating the most pouches.
Practical steps:
Look for food in glass or non-plastic containers when possible. If pouches are part of your rotation, they do not need to be the whole rotation. Read past the front-of-pack claims - "BPA-free" and "organic" are not the same as microplastics-free. Ask brands directly about their packaging materials and what independent testing they have done on food-packaging interaction.
And know that the category is not all the same. Some companies built differently from the start - not as a reaction to bad press, but because the science was always pointing here.
Frequently Asked Questions
What did the Greenpeace microplastics study find in baby food pouches?
The Greenpeace International report Tiny Plastics, Big Problem, published May 20, 2026, commissioned independent lab SINTEF Ocean to test Nestlé's Gerber and Danone's Happy Baby Organics pouches. They found microplastics in every sample tested - up to 54 particles per gram in Gerber pouches and up to 99 per gram in Happy Baby Organics pouches. That translates to an estimated 5,000+ microplastic particles per Gerber pouch and 11,000+ per Happy Baby Organics pouch. The study also found plastic-associated chemicals in both brands, including a potential endocrine-disrupting chemical in the Gerber samples.
Are baby food pouches safe?
The Greenpeace report raises serious concerns about microplastic contamination from the plastic lining of pouches. Every sample tested contained microplastics, and the study suggests the polyethylene lining of the pouches is a likely source. While the long-term health impact of microplastic ingestion in infants is still being studied, the presence of endocrine-disrupting chemicals and the scale of contamination - hundreds of particles per teaspoon - has led pediatric environmental health researchers to urge precaution, particularly during the earliest months of life when developing systems are most vulnerable.
What does "BPA-free" mean for baby food pouches?
BPA-free means the product does not contain bisphenol A, one specific chemical used in some plastics. It does not mean the packaging is free of all plastic chemicals, microplastic particles, or other potentially harmful compounds. The Greenpeace report tested BPA-free pouches and still found microplastics and other plastic-associated chemicals, including a potential endocrine disruptor. BPA-free is a narrow claim that does not address the broader question of what the plastic packaging as a whole is doing to the food inside.
Is organic baby food in pouches free from microplastics?
No. Organic certification applies to how the ingredients are grown and processed - not to the packaging or what the packaging can do to the food. Happy Baby Organics, one of the brands named in the Greenpeace report, is certified organic. Its pouches still contained up to 99 microplastic particles per gram of food. The contamination comes from the plastic container, not the ingredients inside.
Why does Globowl use glass jars instead of pouches?
Glass is inert - it does not leach chemicals or particles into the food it contains. Globowl chose glass packaging because it is microplastics-free and does not interact with the food inside regardless of how long the product sits on a shelf. The decision predates the current microplastics conversation and was made on the science: plastic packaging in contact with food creates contamination risk. Glass does not.
What are endocrine disruptors and why do they matter for babies?
Endocrine disruptors are chemicals that interfere with the body's hormone system. Hormones regulate development - brain function, metabolism, immune response, and reproductive health. Babies are uniquely vulnerable because their hormone systems are still forming, and early exposures can have effects that show up much later in life. The Greenpeace study found a potential endocrine-disrupting chemical in Gerber pouch samples - in both the packaging and the food.
How many microplastics are in a baby food pouch?
According to the Greenpeace International report published May 2026, an estimated 5,000+ microplastic particles in a single Gerber pouch and 11,000+ in a single Happy Baby Organics pouch. At a per-teaspoon level, that is up to 270 particles per teaspoon in Gerber and up to 495 per teaspoon in Happy Baby Organics.
