The supplied infant-food-puree folder does not contain an original laboratory test of packaged puree. Its only paper is a review of microplastics and nanoplastics in infant diets and environments. This page therefore reports an evidence gap. It supplies no particle concentration, polymer distribution, size range, or product ranking for infant puree.1
What this page covers
Infant puree means a prepared, blended food sold or served as puree, including food in a jar or pouch. Research on feeding bottles, water, powdered formula, raw produce, or breast milk addresses related questions, but it is not a direct measurement of finished puree. Those distinctions are especially important when a broad review uses the phrase baby food to discuss many ingredients and feeding routes.1
What the supplied paper provides
Kadac-Czapska and colleagues summarize published work on infant exposure pathways, food-contact products, food ingredients, and biological effects. The review’s food tables include milk, formula, water, produce, meat, and flour, with measurements attributed to other papers. It does not describe its own collection of puree products, extraction from a puree matrix, numerical blanks, or polymer-confirmed puree particles.1

| Evidence in the folder | What it can support | What is not established |
|---|---|---|
| Narrative review of infant diets | Background questions and leads to original papers | A measured concentration in finished infant puree. |
| Secondary tables covering other foods | Identification of related matrices for source retrieval | Transfer of ingredient counts to a jar, pouch, or serving. |
| Discussion of toxicology literature | Recognition that exposure and effect evidence differ | A clinical effect caused by consuming a tested puree. |
Why no number is shown
A numerical result would need a primary experiment on the relevant product, a stated denominator, a measurement window, and chemical identification suited to the recovered particles. Extraction also needs to separate the food matrix from the particles without mistaking natural material for synthetic polymers. Counts from a raw ingredient cannot be added together to manufacture a puree result, and a bottle-release test cannot define what is already in the food.1
What would close the gap
The next evidence needed is an original puree study with identifiable products or anonymized sample groups, particle recovery validation, numerical procedure blanks, clear size measurements, and polymer confirmation. Comparisons of packaging should test matched food under controlled conditions so that differences in ingredients or processing are not attributed to the container. No such primary dataset was available in this category folder.
This gap should not be read as proof that puree is particle-free or as evidence that it is unsafe. It means that the supplied material cannot support a quantitative product conclusion. The review itself emphasizes analytical and translation limits, including difficulty comparing methods and applying experimental toxicology to people. Related categories can be read separately while direct puree evidence is sought.1
Regulatory status
The supplied EFSA statement is a dated scientific assessment that calls for improved methods and quality assurance. Its historical legislative description is not treated as a complete statement of current law. Neither that assessment nor the drinking-water measurement decision supplies a particle limit for this food category.23 A research concentration is not a product compliance determination.
