Greenpeace Raises Alarm After Microplastics Found in Top Companies’ Baby Food Pouches

“Plastic pollution is not just wrecking our environment, it’s entering our bodies, starting from infancy,” said one campaigner. “How our food is packaged is designed for profit, not for people’s health.”

COMMON DREAMS

Parents often reach for squeeze pouches of baby food to feed little ones on the go or because they aren’t likely to break if dropped from a high chair, but research commissioned by Greenpeace International and released Thursday raises concerns about how the convenient packaging is exposing children to microplastics and plastic-associated chemicals, with potential health risks.

“In supermarkets worldwide, shelves are now lined with these soft plastic squeeze pouches of pureed baby food, promoted with safety and environmental claims such as ‘BPA-free,’ ‘non-GMO,’ ‘pesticide-free’ and ‘organic,’” notes the group’s new report, “Tiny Plastics, Big Problem: The Hidden Risks of Plastic Pouches for Baby Food.”

“In the US alone, it has been reported that sales of baby food pouches skyrocketed by approximately 900% between 2010 and 2023, becoming a dominant format for baby nutrition,” the report continues. Given the rising popularity of pouches, Greenpeace had SINTEF Ocean conduct laboratory testing of Danone’s Happy Baby Organics and Nestlé's Gerber pureed baby food.

The researchers found up to 54 microplastic particles in Gerber yogurt pouches and up to 99 particles in Happy Baby Organics fruit pouches, on average—or as many as 270 microplastics per teaspoon in the former and 495 in the latter. They estimated that a full pouch of Gerber contains more than 5,000 particles, while Happy Baby has over 11,000 particles.

“Spectral analysis identified polypropylene (PP) and polyamide (PA), as well as tentatively identifying polyethylene (PE),” the report explains. “Particles tentatively identified as PE microplastic were the most abundant, occurring at similar levels in both products. This suggests that abrasion or degradation of the inner PE lining in contact with the food may contribute to the microplastic content in the food.”

The experts also examined chemicals in the pouched food, and “tentatively identified 81 chemicals in the Danone fruit puree and 111 in the Nestlé dairy-based puree, which were also detected in the respective packaging materials,” according to the report.

“Cross-referencing with the PlastChem database, an inventory of chemicals known to be used in or found in plastics, revealed that 55 of the substances found in the fruit sample and 28 in the dairy sample were identified as plastic-associated chemicals,” the publication notes. “One chemical found in both the packaging and the yogurt was tentatively identified as 2,4-di-tert-butylphenol (2,4-DTBP), a chemical of concern. It is recognized as hazardous to human health and the environment, has been associated with endocrine-disrupting effects, and could also act as an obesogen.”

“Our findings are not occurring in isolation,” the report emphasizes, citing other research on baby food pouches, infant bottles, and other plastic packaging, including breast milk storage bags. “Wherever we look with the right tools, we find the fingerprints of plastics permeating baby foods.”

The document also acknowledges that “besides the potential health risks of microplastics and plastic chemicals on babies, concerns have been raised by public health nutritionists about the growing market for spout pouches and their nutritional impact on babies and toddlers, specifically the high levels of sugars and low mineral and vitamin content in many products.”

“Overreliance on spout pouches is starting to be associated with growing levels of dental decay and obesity amongst young children,” the report adds, pointing to warnings from the World Health Organization and the United Kingdom’s National Health Service that “babies can eat too fast when they suck directly from the pouch.”

Considering the findings, “delaying action is not just ill-advised, it’s unethical,” Greenpeace argued. “Governments must work nationally and globally to secure a strong global plastics treaty that dramatically reduces global plastic production, eliminates hazardous plastics and associated chemicals, and drives a justice-centered, at-scale transition to reuse-based systems.”

Several rounds of negotiations on crafting a United Nations treaty to combat plastic pollution have been largely fruitless. In March, the chair of the talks, Chilean diplomat Julio Cordano, released a roadmap to renew the global push for a deal. Following that release, another round of talks is expected later this year or next year.



The Greenpeace report doesn’t just put pressure on governments. It also says that “all companies that rely on plastic packaging must reconsider their business model, prioritizing baby food, baby products, and food contact packaging. Nontoxic, plastic-free, zero-waste, reuse-centered product delivery systems and packaging alternatives already exist in communities around the world.”

“Nestlé and Danone, and other major consumer goods companies and supermarket chains must take responsibility by swapping flexible packaging for healthier alternatives and supporting policies that accelerate reuse system expansion,” it stresses.

Graham Forbes, Greenpeace USA’s global plastics campaign lead, declared that “this study is a wake-up call for parents everywhere, who trust these brands to put their kids first. Plastic-dependent companies like Nestlé and Danone owe families a clear answer: What are they doing to eliminate microplastics and chemicals from the products they sell to babies?”

“Plastic pollution is not just wrecking our environment, it’s entering our bodies, starting from infancy,” Forbes added. “How our food is packaged is designed for profit, not for people’s health. Cutting plastic production and eliminating harmful chemicals is essential to protect human health, especially the health of our children.”

Thames microplastics research targets policy reform



New River Thames monitoring project aims to shape future environmental regulation



University of East London





Researchers at the University of East London (UEL) are launching a new study into microplastic pollution in the River Thames in a bid to influence environmental policy and water quality.

The project, led by Dr Ria Devereux from UEL’s Sustainability Research Institute, will gather data from locations stretching from Teddington to Southend to assess how pollution levels are changing and what impact climate pressures may be having on the river system.

Building on more than three years of continuous monitoring and research, the study will combine new sampling with existing datasets to provide updated evidence on microplastic contamination across the Thames.

The research team includes Dr Ravindra Jayaratne, Reader in Coastal Engineering at UEL’s School of Architecture, Computing and Engineering (ACE), whose international work on flood resilience and environmental modelling has helped inform coastal policy and engineering standards in the UK and overseas.

The researchers say the findings could help shape future discussions around wastewater management, river protection and plastic pollution policy at local and national level.

Dr Devereux’s research into microplastics in the River Thames has already attracted international attention while her work has also been referenced in UK Government and environmental advisory reports.

The new project will involve engagement with stakeholders including the Environment Agency, DEFRA, the Port of London Authority, water companies and environmental organisations.

Dr Devereux said:

“The River Thames is one of the most internationally recognised urban rivers in the world, yet we are still learning about the scale and complexity of microplastic pollution within it.

“This project is about providing robust scientific evidence that can support better environmental decision-making and help policymakers understand where interventions may be needed most.”

The study will also examine how storm activity and changing environmental conditions may influence microplastic levels across the river system.

Alongside scientific analysis, the project will produce policy briefings and bring together regulators, environmental organisations and policymakers through a dedicated stakeholder workshop hosted at UEL’s Royal Docks Centre for Sustainability.

Dr Jayaratne said:

“Environmental challenges such as microplastic pollution require long-term evidence, interdisciplinary collaboration and strong engagement with policymakers.

“By combining environmental monitoring with engineering and policy expertise, we hope this work will help support more informed environmental management and future regulatory discussions.”

Dr Devereux added:

“Microplastic pollution is not just an environmental issue - it is increasingly linked to wider discussions around public health, water quality and climate resilience.

“We want this work to help bridge the gap between scientific research and practical policy action.”


Can aerobic exercise lessen the health effects of exposure to nanoplastics?



Wiley





Using female zebrafish as a model, researchers have found that aerobic exercise may influence various connections in the body to lessen the damaging health impacts of environmental nanoplastics.

In the study, which is published in The FASEB Journal, adult female zebrafish were exposed to polystyrene nanoplastics for 21 days, with or without moderate aerobic exercise.

“Once ingested, nanoplastics may cross epithelial barriers and accumulate in multiple organs, including the liver, heart, brain, and ovary, eliciting oxidative stress, inflammation, and endocrine disruption,” the authors wrote. “Among these targets, the ovary appears particularly susceptible, yet the mechanisms underlying nanoplastic-induced ovarian accumulation and toxicity remain poorly characterized.”

Exposure to nanoplastics alone caused significant ovarian accumulation of particle-like structures, elevated oxidative stress, increased follicular cell death, and disrupted reproductive hormones. It also induced anxiety‑ and depression-like behaviors in tank and shoaling tests, accompanied by elevated stress hormone levels. In contrast, concurrent aerobic exercise lessened these effects.

Investigators also found that aerobic exercise counteracted gut microbe imbalances caused by nanoplastics. Analyses linked these microbial shifts to enhanced fatty acid and tryptophan metabolism, which correlated with improved neuroendocrine health.

The findings indicate that aerobic exercise may mitigate nanoplastic-induced neuroendocrine dysfunction via gut–ovary–brain connections.

Brain Health emergency: Microplastic burden in the human brain now linked to stroke and dementia, with apheresis emerging as the first plausible removal pathway



New Brain Health Perspective from Genomic Press converges measurement, mechanism, and intervention as the field moves from alarm to action

NEW YORK, 5 May 2026 — In a Perspective published today in the inaugural issue of Brain Health (https://doi.org/10.61373/bh026p.0006), an international team of investigators argues that the human microplastic burden has crossed the threshold from environmental concern to brain health emergency. The article appears alongside the launch of Brain Health, a new peer-reviewed journal from Genomic Press dedicated to the science of lifelong brain resilience.

The Perspective synthesizes evidence across three domains that until recently sat in separate scientific silos. Decedent human brain tissue, sampled from a 2016 to 2024 cohort and analyzed by Nihart and colleagues at the University of New Mexico, carries microplastic concentrations seven to thirty times higher than matched samples of liver or kidney. The cumulative tissue burden rose by approximately fifty percent across that eight-year window. Donors with diagnosed dementia carried the heaviest loads. Polyethylene predominated, presenting largely as nanoscale, shard-like fragments.

The cardiovascular evidence is now equally striking. Marfella and colleagues, working with patients undergoing carotid endarterectomy, identified microplastics and nanoplastics inside atheromatous plaque. Patients whose plaque tested positive for these particles experienced a roughly fourfold increase in the composite risk of myocardial infarction, stroke, or death over thirty-four weeks of follow-up. As the new Perspective notes, this is a brain finding as much as a cardiac one, because stroke is a brain outcome.

How do these particles reach the brain in the first place? Animal data are now closing that gap. Polystyrene nanoparticles administered orally to mice were shown by Kopatz and colleagues to cross the blood-brain barrier within two hours of exposure, with the biomolecular corona acquired in transit functioning as the passport for entry. Larger particles do not cross. Nanoscale particles do.

“We are looking at an organ where the highest measured concentrations of microplastics meet the most consequential clinical endpoints in medicine,” says Dr. Julio Licinio, lead author of the Perspective and Publisher and CEO of Genomic Press. “Cognition, mood, stroke, dementia. Treating this as a peripheral environmental concern, when the relevant peripheral organs carry less of the contaminant than the central one, has become difficult to defend.”

The Perspective also foregrounds a delivery vehicle that operates at population scale: ultra-processed food. Group 4 of the NOVA classification, ultra-processed foods now supply more than half of caloric intake in the United States. They are also high-throughput vectors for microplastic exposure, through packaging migration during heating and storage, mechanical wear during industrial processing, and downstream contamination. Independent of microplastic content, ultra-processed food consumption has been linked in large prospective cohorts to depression, anxiety, cognitive decline, stroke, and dementia. A meta-analysis of 385,541 participants found a fifty-three percent increase in the odds of common mental disorder symptoms in those with the highest ultra-processed food intake. UK Biobank data link the same dietary pattern to increased dementia risk. The REGARDS cohort showed that a ten percent rise in relative ultra-processed food intake was associated with a sixteen percent increase in cognitive impairment risk and an eight percent increase in stroke risk, holding independently of adherence to Mediterranean, DASH, or MIND dietary patterns.

“The boundary between physical and mental health has always been more administrative than biological,” notes Dr. Nicholas Fabiano of the University of Ottawa Department of Psychiatry, a co-author on the Perspective. “Microplastics do not respect that boundary. The same particles that lodge in atheroma also reach the brain. The same dietary exposures that raise cardiovascular risk also raise risk for depression and dementia. We are looking at one problem with many clinical faces.”

The Perspective treats removal as the next frontier rather than a distant aspiration. Bornstein and colleagues, working at the University Hospital Carl Gustav Carus in Dresden, recently reported that therapeutic apheresis can extract material consistent with microplastic particles from human plasma. The mechanism is biologically plausible. The clinical infrastructure already exists in tertiary centers worldwide. On present evidence, apheresis is the most promising candidate intervention the field has produced.

“We were initially surprised by what we observed,” says Dr. Stefan R. Bornstein of Technische Universität Dresden and King’s College London, senior co-author. “Apheresis is an established clinical modality. The fact that it appears to engage these particles in vivo opens a path that did not exist a year ago. The work now is to validate the signal against measurement standards the broader scientific community can agree on, and to develop scalable alternatives matched to polymer specificity, tissue compartment, and patient population.”

“What the field still lacks is the measurement infrastructure that would let us rank polymers by harm and confirm that interventions are working,” adds Dr. Charlotte Steenblock, also of Technische Universität Dresden and a co-author. “Without validated, reproducible, polymer-specific quantification, no removal strategy can be confirmed in the strict sense. That is not a weakness of the apheresis approach. It is a feature of a field operating ahead of its own analytical tools.”

The authors note that the science of brain health, at the level of national funding priority, is now moving toward subtraction with the same seriousness it has long given to addition. In April 2026, ARPA-H, the agency built on the model that produced GPS, the early Internet, and the foundational work behind mRNA vaccines, launched STOMP: Systematic Targeting Of MicroPlastics. The program is organized around the same three priorities the new Perspective identifies: develop measurements that can characterize nanoscale particles in complex biological tissue, illuminate the mechanisms by which microplastics traffic through organs and cause harm, and translate that knowledge into clinical removal.

Vulnerable populations sit at the center of the policy question. Microplastics have been localized within the intracellular compartment of human placenta, implying fetal exposure during the most consequential window of neurodevelopment. Children, with developing blood-brain barriers and higher per-kilogram intake than adults, carry a lifetime burden trajectory that today’s adult cohorts cannot predict. Patients with established cerebrovascular disease, in whom the Marfella signal becomes most clinically relevant, are already in clinics today. So are patients with neurodegenerative disease, in whom the Nihart finding of disproportionately high brain burden raises a question that will not go away: are these particles passenger, accelerator, or contributor?

In the absence of a validated clinical removal modality, the Perspective notes, population-scale exposure reduction is currently achievable only by reducing ultra-processed food consumption. That is not a trivial intervention. It is, however, the one lever the field has at present that operates at the scale of the problem.

The peer-reviewed Perspective, “The human microplastic burden and brain health: from measurement to pathophysiology and removal,” appears online on 5 May 2026 in Brain Health, in the journal’s inaugural issue, and is freely accessible at https://doi.org/10.61373/bh026p.0006.

Brussels instructs EU countries to be tough on net-zero shipping goals at key IMO talks

The high-level talks come after a disastrous meeting in October, when a proposal to tax shipping emissions was blocked by the United States. Within the EU, Greece, Italy and Malta remain hesitant to support the proposal.

The European Union looks to enforce stricter limits on greenhouse gas emissions from ships during high-level talks in London this week, risking a fresh clash with the United States, which last October blocked a global tax on carbon emissions.\\\

The London-based International Maritime Organization (IMO) had hoped governments would back its “net-zero framework” for shipping, which would impose charges per metric ton of carbon dioxide emitted above certain limits.

However, the proposal was rejected during talks at the UN maritime body last autumn, with 57 countries voting in favour of a one-year delay, including the United States, Saudi Arabia and Russia.

While no vote is expected during the April round of talks, EU countries have been instructed to act together to support climate goals in line with international commitments and the bloc’s target of reaching climate neutrality by 2050, according to a letter seen by Euronews.

“Member states, on behalf of the Union, shall oppose any attempts to remove the IMO Net-Zero Framework,” the letter states.

IMO calls for ‘constructive talks’

IMO Secretary-General Arsenio Dominguez urged delegates to engage in constructive and pragmatic discussions, saying “there is no need to repeat what happened last October”, when US President Donald Trump blocked the vote, with several reports suggesting Washington pressured some countries over trade tariffs.

“Let us move forward where we agree and continue to work on areas where further effort and understanding are needed. At a time when there is already enough disagreement around the world, I ask that we set an example of effective multilateralism,” Dominguez said on 27 April.

Anaïs Rios, senior policy officer for shipping and climate at the NGO Seas at Risk, criticised the US Trump administration’s pushback against “any progress towards clean energy”, which she said has left many countries undecided.

“Progress is at risk of stalling amid continued opposition and delays to anything that could advance the framework towards decarbonising shipping, which was approved last year but has yet to be adopted,” said Rios, who is attending the IMO talks.

Defending and exporting domestic climate goals

The EU’s net-zero rules for shipping require a 2% cut in greenhouse gas emissions in 2025, rising to 6% in 2030 and gradually increasing to 80% by 2050 for ships above 5,000 gross tonnage.

While the bloc aims to defend its climate goals, it also intends to work closely with international partners through the IMO to develop global rather than regional solutions, the letter states, as international shipping accounts for around 2–3% of global emissions.

Brussels insists any final agreement must still meet the agreed target of net-zero emissions by 2050. However, it also stresses that the transition must preserve the competitiveness of Europe’s maritime sector and ensure a global level playing field.

The approach reflects an underlying tension, as the bloc risks placing its own industry at a disadvantage if other countries do not match its level of ambition.

A revised compromise text currently under discussion at the London talks has secured broad backing among EU countries, although Greece, Italy and Malta remain cautious, according to two EU diplomats.

Pricing shipping emissions

Countries voted in April 2025 on adopting a global framework to introduce a carbon price on shipping emissions, aimed at helping the industry decarbonise and encouraging cleaner technologies.

On 16 October 2025, a simple majority of 54 votes was required for adoption, but the proposal fell short, with 49 votes in favour.

The proposed IMO levy would range from $100 (€85) to $380 (€324) per metric ton, depending on various factors, and could generate between $30 billion (€26.51 billion) and $40 billion (€34.15 billion) by 2030, while delivering at least a 10% reduction in emissions from the sector, according to estimates from environmental organisations.

The carbon pricing mechanism would be paid by ship owners into a UN “Net Zero Fund”, which would be managed by the IMO and used to support green shipping innovation and reward low-emission vessels.

US President Donald Trump rejected the proposal, calling it a “global green new scam” and arguing it would drive up costs for American consumers.

A study conducted at the Institute of Science and Technology of São Paulo State University (ICT-UNESP) in São José dos Campos, Brazil, shows that Moringa oleifera, also known as moringa or white acacia, has the potential to remove microplastics from water.

The study was published in the journal ACS Omega, published by the American Chemical Society.

Moringa is native to India and well-adapted to various tropical countries. It is used for a variety of purposes, such as food, through the consumption of its leaves and seeds, which are nutritious. For several years, researchers have studied the potential of the seeds in water treatment.

“We showed that the saline extract from the seeds performs similarly to aluminum sulfate, which is used in treatment plants to coagulate water containing microplastics. In more alkaline waters, it performed even better than the chemical product,” says Gabrielle Batista, the first author of the study. She conducted the research as part of her master’s degree in the Post-Graduate Program in Civil and Environmental Engineering (PPGECA) at the Bauru School of Engineering (FEB) at UNESP.

Adriano Gonçalves dos Reis, a professor at ICT-UNESP and in the PPGECA at FEB-UNESP, coordinated the research and also leads the project “Direct and In-Line Filtration for the Removal of Microplastics from Drinking Water”, which is supported by FAPESP.

“The only drawback found so far regarding aluminum sulfate was the increase in dissolved organic matter, the removal of which could make the process more expensive. However, on a small scale, such as on rural properties and in small communities, the method could be used cost-effectively and efficiently,” says Reis.

The study focused on water treatment via in-line filtration. In this process, the water is coagulated, which destabilizes the particles, and then it passes through a sand filter. This treatment method is suitable for water with low turbidity, meaning it is clearer and does not require as many preliminary processes.

Coagulation is essential because pollutants, such as microplastics, have a negative electrical charge on their surface and repel each other and the sand in water treatment filters. Coagulants, such as moringa salt extract (which can be made at home) and aluminum sulfate, neutralize this charge. This causes the pollutants to clump together so they can be filtered out.

In a previous study, the group demonstrated the effectiveness of moringa seeds for coagulation in a complete water treatment cycle, which also involves flocculation, sedimentation, and filtration. Luiz Gustavo Rodrigues Godoy, the first author of the study, completed his master’s degree with a scholarship from FAPESP at FEB-UNESP.

Experiments

To test the effectiveness of the water treatment method, the researchers used tap water that they contaminated with polyvinyl chloride (PVC).

Microplastics from this source were chosen because PVC is one of the most dangerous plastics for human health due to its documented mutagenic and carcinogenic potential. PVC is also prevalent on the surfaces of water bodies and in water treated by traditional processes.

They artificially aged the PVC using ultraviolet radiation to mimic natural processes and reproduce the properties of naturally aged microplastics.

The microplastic-contaminated water underwent coagulation and filtration in a Jar Test, a device that replicates water treatment processes on a small scale. The results were then compared to those of the same tests performed on water treated with aluminum sulfate, a compound used in traditional treatments.

Scanning electron microscopy (SEM) was used to count the microplastic particles before and after treatment. The size of the flocs formed by the different treatments was measured using a high-speed camera and a laser beam; no significant differences in particle removal were found.

The group is now testing moringa seed extract using water collected directly from the Paraíba do Sul River, which supplies São José dos Campos. In the experiments conducted thus far, the product has proven quite effective in treating natural water.

“There’s increasing regulatory scrutiny and health concerns regarding the use of aluminum- and iron-based coagulants, as they aren’t biodegradable, leave residual toxicity, and pose a risk of disease. For that reason, the search for sustainable alternatives has intensified,” Reis concludes.
