Quick Answer

A 2025 Greenpeace-commissioned study (conducted by SINTEF Ocean) tested Gerber and Happy Baby Organics baby food pouches and found 5,000 to 11,000 microplastic particles per single pouchand 28 to 55 plastic-associated chemicals. Plastic pouches are the fastest-growing baby-food packaging format (37% of global market by volume in 2025). The polyethylene pouch liner is the primary source. Safer alternatives: glass jars (Beech-Nut Naturals glass, Once Upon a Farm glass, Serenity Kids glass varieties)or homemade purées in glass storage.

Key Takeaways

The 2025 SINTEF / Greenpeace study found 5,000–11,000 microplastic particles per single Gerber or Happy Baby Organics pouch.
Gerber pouches: up to 54 particles per gram of food. Happy Baby Organics: up to 99 particles per gram.
28-55 plastic-associated chemicals (plasticisers, antioxidants, processing aids) were detected in tested pouches.
Polyethylene pouch liner is the primary contamination source, direct contact with acidic fruit purées accelerates leaching.
Plastic pouch market is the fastest-growing baby food packaging at 8.18% annual growth, now 37% of global volume by 2025.
Glass-jar alternatives (Beech-Nut Naturals Glass, Once Upon a Farm glass varieties, Serenity Kids glass) eliminate this exposure.

The 2025 Greenpeace / SINTEF study

Commissioned by Greenpeace International and conducted by SINTEF Ocean (Norway) in 2025, this independent lab study tested two of the best-selling baby food brands in the US:

Nestlé Gerber yoghurt-based purée pouches
Danone Happy Baby Organics fruit-based purée pouches

The findings, published May 22, 2026 via Greenpeace International press release:

5,000 to 11,000 microplastic particles per pouch (varied by product).
Up to 54 particles per gram of food in Gerber.
Up to 99 particles per gram in Happy Baby Organics.
28 to 55 plastic-associated chemicals in the food.
Polyethylene was the dominant polymer, matching the pouch liner material.

Why pouches are uniquely contaminating

Multi-layer flexible plastic. Most pouches are PE + aluminium foil + PET laminate. The food-contact layer is polyethylene, sometimes LDPE for soft pouches.
Acidic content. Most baby food (fruit purées, tomato sauce, yoghurt) is acidic, accelerating leaching from polyethylene.
Long shelf life. Pouches typically sit on shelves and in pantries for 6–18 months before consumption.
Heat exposure. Warming pouches (running under hot tap water or (worse) microwaving) accelerates particle release.
Squeezing during use. Babies and parents squeeze the pouch, abrading the inner liner with each use.
Plastic spout. Adds an additional polypropylene contact point that the baby's mouth touches directly.

Baby food packaging compared

Baby food packaging by microplastic exposure
Packaging	Particles per serving	Notes
Homemade purée in glass jar	Lowest	Full control over ingredients and container
Glass jar baby food (Beech-Nut Naturals Glass, Once Upon a Farm glass, Serenity Kids glass)	Low	Only the metal lid is plastic-coated
Frozen baby food cubes (your own glass storage)	Low	Make in batches, freeze, thaw as needed
Plastic baby food cups (Gerber 2-pack tubs)	Higher	PP cups with foil lid; less than pouches per gram
Plastic squeeze pouches (Gerber, Happy Baby, Plum, GoGo)	Highest	5,000-11,000 particles per pouch per Greenpeace 2025

Recommended glass-jar baby food brands

Beech-Nut Naturals Glass, single-ingredient and blended fruit/veg in glass jars.
Once Upon a Farm, refrigerated organic baby food, some lines in glass.
Serenity Kids, savory baby food blends, some glass jar varieties.
Square Baby, meal-delivery service in glass; subscription model.
European brands (HiPP Glass, Holle Glass). European baby food brands have stronger regulations and broader glass availability.
Homemade in mason jars or small Weck jars, single steamed/blended fruit or veg, stored in glass.

Practical transition plan for parents currently using pouches

Stop microwaving pouches immediately, heat dramatically accelerates leaching. Squeeze contents into a glass bowl to warm.
Switch to glass-jar baby food for at-home feeding.
Use refillable silicone pouches (Squooshi, Yumbox Aqua) when convenience matters, fill with homemade purée.
Make 1 week of purées on Sunday and freeze in glass containers. Thaw overnight.
For travel, use glass jars or refillable silicone pouches, not disposable plastic pouches.
Skip the on-pouch spout if you do use pouches, squeeze into a glass bowl with a spoon instead of direct mouth contact.

Frequently Asked Questions

Are baby food pouches safe?

A 2025 Greenpeace-commissioned SINTEF Ocean study found 5,000-11,000 microplastic particles and 28-55 plastic-associated chemicals in a single Gerber or Happy Baby Organics pouch. Glass-jar baby food eliminates this exposure source.

Which baby food brands are sold in glass jars?

Beech-Nut Naturals Glass, Once Upon a Farm (some lines), Serenity Kids (glass varieties), Square Baby (subscription glass), and European brands HiPP Glass and Holle Glass. Mason jars work great for homemade purées.

Can I warm a baby food pouch in the microwave?

No: never microwave plastic baby food pouches. Heat dramatically accelerates microplastic and chemical leaching. Squeeze contents into a glass bowl first if you need to warm.

Are refillable silicone baby food pouches safer?

Yes: refillable silicone pouches (Squooshi, Yumbox Aqua) release dramatically fewer microplastics than disposable PE plastic pouches and let you fill with homemade purées. Best of both worlds: convenience plus low microplastic.

Is Gerber baby food bad for babies?

Specifically Gerber pouches had up to 54 microplastic particles per gram of food in the 2025 SINTEF study. Gerber's glass-jar single-ingredient line is far cleaner. Brand isn't the issue, packaging format is.

How can I make homemade baby food?

Steam fruit or vegetables, blend with a hand blender in a glass jar, and store in glass containers (mason jars or Weck jars) in the fridge for 3-5 days or freezer for 1-2 months. Simple, dramatically cleaner, and far cheaper than pouches.

Yes: keep pumping. The benefits of breast milk clearly outweigh microplastic concerns. But polypropylene flanges and bottles do shed particles with heat and friction. Medela vs Spectra vs Elvie vs glass-bottle setups compared, plus the wash routine that cuts exposure most.
