Babies are surrounded by plastic, yet may be most vulnerable to its impacts.
In laboratories commissioned by Greenpeace International, the plastic pouches trusted by millions of parents to nourish their youngest children were found to carry thousands of microplastic particles per serving — a quiet contamination embedded not in error, but in the very materials chosen by two of the world's most powerful food corporations. Nestlé's Gerber and Danone's Happy Baby Organics, together commanding nearly half the global baby food market, have become vessels for polyethylene fragments and endocrine-disrupting chemicals delivered during the most vulnerable window of human development. The findings arrive as a reminder that the plastic crisis is not only an environmental abstraction but an intimate one — present in the first foods a child ever tastes.
- Independent lab tests found up to 11,000 microplastic particles in a single Happy Baby Organics pouch and over 5,000 in a Gerber pouch — not from contamination errors, but from the packaging itself breaking down.
- Endocrine-disrupting chemicals were also detected, raising alarm about hormonal interference in infants whose developmental systems are at their most fragile and formative.
- Nestlé and Danone, despite years of public pressure and voluntary plastic-reduction pledges, have made no fundamental changes to their reliance on plastic pouches — a gap between promise and practice now measured in particles per gram.
- Greenpeace is calling on both companies to abandon plastic pouches entirely and shift to non-toxic, reusable, refillable packaging systems as the only credible path forward.
- The broader demand is structural: advocates argue that only a binding Global Plastics Treaty regulating production and packaging at scale can prevent the next generation from bearing the full cost of inaction.
A Greenpeace International investigation has uncovered thousands of microplastic particles per serving inside the plastic squeeze pouches used by Nestlé's Gerber and Danone's Happy Baby Organics — two brands that together hold roughly 40 percent of the global baby food market. Independent laboratory testing found an average of 54 microplastics per gram in Gerber pouches and 99 per gram in Happy Baby Organics pouches. Across a full serving, that amounts to more than 5,000 particles in each Gerber pouch and more than 11,000 in each Happy Baby Organics pouch.
The source appears to be the polyethylene lining of the pouches themselves, degrading over time and shedding particles directly into the food. Beyond microplastics, tests also detected an endocrine-disrupting chemical in the Gerber yoghurt product — a substance capable of interfering with hormone systems at precisely the developmental stage when such interference carries the greatest risk. This is not a story of manufacturing accidents; it is a story of materials behaving as plastics inevitably do.
Greenpeace frames the findings as a failure of corporate accountability. Both Nestlé and Danone have made public commitments to reduce plastic use, yet neither has moved away from plastic pouches or introduced meaningful protections against leaching. Together, the two companies produce more than a million tonnes of plastic packaging annually. Their certifications and compliance frameworks, the report argues, have not been enough to keep microplastics and harmful chemicals out of infant food.
The report calls on both companies to replace plastic pouches with non-toxic, reusable, refillable alternatives — and situates that demand within a larger argument for systemic change. Plastic packaging represents roughly 40 percent of all global plastic production. As it fragments, it enters ecosystems, food chains, and human bodies. Infants, whose digestive and immune systems are still forming, may face particular vulnerability, though the long-term consequences remain incompletely understood. Greenpeace argues that without a strong, binding Global Plastics Treaty to regulate production at scale, the burden of the plastic crisis will fall heaviest on those who had no voice in creating it.
A Greenpeace International investigation has found that plastic pouches used to package baby food from two of the world's largest manufacturers contain thousands of microplastic particles per serving. The study commissioned an independent laboratory to test Nestlé's Gerber brand yoghurt-based puree and Danone's Happy Baby Organics fruit-based puree, both sold in the distinctive squeeze-and-suck plastic pouches that have become ubiquitous in supermarket baby food aisles worldwide. The results were stark: a single gram of food—roughly the weight of a raisin—contained an average of 54 microplastics in Gerber pouches and 99 in Happy Baby Organics pouches. Scaled to a full serving, this translates to more than 5,000 particles in each Gerber pouch and more than 11,000 in each Happy Baby Organics pouch.
The research suggests that polyethylene, the plastic material lining the pouches, is breaking down and releasing these particles directly into the food babies consume. The tests also detected a range of chemicals in both the packaging and the food itself, including an endocrine-disrupting chemical in the Gerber yoghurt product. Endocrine disruptors are substances that interfere with hormone systems, raising particular concern during infancy and early childhood when developmental processes are most vulnerable. The contamination appears to stem not from manufacturing defects or human error, but from the inherent instability of the plastic packaging itself as it degrades over time.
Nestlé and Danone together control approximately 40 percent of the global baby food market, making their packaging choices consequential for millions of families. Parents purchasing these products have placed their trust in established brands to protect their infants from contamination. The Greenpeace report frames this as a failure of corporate responsibility: despite years of public pressure and voluntary commitments to reduce plastic use, neither company has fundamentally altered its reliance on plastic pouches or implemented meaningful safeguards against microplastic leaching. The companies' existing certifications and compliance efforts, the report argues, have proven insufficient to prevent microplastics and harmful chemicals from reaching the food itself.
The broader context makes the findings more troubling. Plastic packaging accounts for roughly 40 percent of all global plastic production and waste. As plastic breaks down in the environment, it fragments into microplastics that circulate through ecosystems, accumulate in food chains, and enter human bodies through air, water, and food. Babies, whose digestive and immune systems are still developing, may be particularly vulnerable to the effects of microplastic and chemical exposure, though the long-term health impacts remain incompletely understood. The fact that infants are being exposed during critical developmental windows adds urgency to the question of what these particles and chemicals might do over a lifetime.
Nestlé and Danone have long been identified as among the world's largest plastic polluters. According to audits by the Break Free from Plastic movement, the two companies together produce more than a million tonnes of plastic packaging annually. Their voluntary commitments to reduce plastic use have not translated into systemic change within their operations or the broader industry. The Greenpeace report calls for both companies to abandon plastic pouches entirely in favor of non-toxic, plastic-free reusable containers and refill systems. More broadly, it frames the microplastics in baby food as evidence that addressing the plastic crisis requires not incremental improvements but fundamental system change—including a strong Global Plastics Treaty that would regulate plastic production and packaging at a global scale. Without such intervention, the report suggests, the cost of inaction will be borne by the next generation.

The Hearth Conversation Another angle on the story
Why does it matter that these are baby food pouches specifically? Isn't microplastic contamination a problem everywhere?
It matters because babies are uniquely vulnerable. Their organs are still forming, their immune systems are developing, and they have decades ahead of them to accumulate whatever damage these particles might cause. We're talking about exposing infants to thousands of microplastics at a time when their bodies are most plastic—most changeable, most susceptible to harm.
The numbers are striking—5,000 to 11,000 particles per pouch. How did the companies not catch this?
That's the question, isn't it. This isn't a manufacturing accident or a batch that slipped through quality control. The polyethylene lining is literally breaking down as the food sits in the pouch. The companies may have known this was possible, or they may have simply never looked closely enough to ask the question.
What would replacing these pouches actually look like?
Glass jars, metal containers, refillable systems where parents bring containers back to be refilled. It's not revolutionary—it's how baby food was packaged before plastic became cheap and convenient. The barrier isn't technology. It's that plastic is profitable and the cost of switching is real money.
But aren't these companies already making commitments to reduce plastic?
They are, but the commitments are voluntary and vague. They've had years to act meaningfully and haven't. That's why Greenpeace is calling for a Global Plastics Treaty—something with teeth, with legal force, that doesn't let companies set their own timelines and definitions of progress.
What happens to a baby who eats food from these pouches?
We don't fully know yet. That's part of what makes this urgent. The microplastics are there. The chemicals are there. The long-term effects are still being studied. But we're not waiting for perfect certainty before we expose infants to them—we're just doing it, because it's convenient and profitable.
