Plastics and family health: practical choices
If reducing plastic contact with food is a priority, start with how you heat, store and serve it. Small, affordable changes can be more useful than replacing everything at once.

Three useful places to start
Start with heating food
If you want less plastic contact during reheating, use a glass or ceramic container specifically suitable for the microwave. For any container, follow its food, temperature and cleaning limits: food-grade does not mean suitable for every use. Metal generally does not belong in a microwave.

Choose reusable items suited to the job
For food storage and drinks, suitable glass or stainless steel can be alternatives when you want to reduce plastic contact. Glass can break, and an item must suit your child’s stage. With any material, use containers designed for repeated food use and replace damaged items; disposable packaging is not made for repeated washing.

Look beyond a reassuring label
For textiles, OEKO-TEX STANDARD 100 means testing against limits for specified harmful substances. Product Class 1 has the strictest requirements and covers babies and children up to three years. Match the certificate to the exact item and covered components. Natural fibres or a BPA-free claim alone do not establish that a whole product has been tested for other substances.

Work within your budget and keep useful products that remain suitable for their intended use. Material preferences do not replace safe sleep, correct cot–mattress fit, feeding hygiene or a product’s instructions. Do not change formula preparation, sterilisation or prescribed medical care to avoid plastic.
What does this mean in Australia?
Regulators do not all interpret the BPA evidence in the same way. FSANZ’s October 2025 advice says Australian dietary exposure is low and unlikely to pose a health risk, and explains its reservations about EFSA’s much lower European intake threshold. These are different assessments, not a single agreed worldwide limit. Choosing suitable non-plastic food containers is an option for families who prefer to reduce contact; the research is not a reason to assume all packaged food is unsafe.
What the research tells us
Research links some chemicals used in plastics with health concerns. These findings deserve attention, but they do not mean every plastic contains the same chemicals or that a particular baby product has caused harm. Chemical additives and tiny plastic particles are different topics; evidence about one does not automatically establish the effects of the other.
A place to explore the wider evidence — Yannick Mulders et al., 2026
What was studied: Research dashboard and editorial describing an updated synthesis of systematic reviews and meta-analyses.
Boston College and Minderoo Foundation’s PlasticHealthAware brings together human-health research on groups including bisphenols, phthalates, PFAS, PBDEs and PCBs. It is a useful way to explore the research behind concerns about plastic-associated chemicals.
Keep in mind: It does not test or certify individual products. Its chemical findings should not be treated as proof of the health effects of all polymers or microplastics.

BPA during pregnancy and child development — Christos Symeonides et al., 2024
What was studied: Observational analysis of the Australian Barwon Infant Study, alongside laboratory and mouse experiments.
Higher measured prenatal BPA was associated with autism outcomes in boys with a low genetic score for aromatase pathway activity. Aromatase is an enzyme involved in hormone production.
Keep in mind: This was a particular subgroup, not a risk estimate for all boys or all pregnancies. The human association cannot establish that BPA caused an individual child’s autism. The mouse experiments do not establish a treatment for children.

Phthalates, inflammation and child development — Ahmed Elagali et al., 2025
What was studied: Observational gene–environment analysis in the Barwon Infant Study.
The researchers examined how prenatal phthalate exposure and genetic susceptibility to inflammation related to later neurodevelopment. They reported interactions between DEHP exposure and the inflammation score for some autism outcomes.
Keep in mind: The roughly doubled odds of autism and ADHD reported in the abstract refer to the high genetic inflammation score, not phthalate exposure alone. This and the BPA study draw on the same birth cohort; they are not two independent population replications. Neither study shows that a parent caused, or could have prevented, a child’s diagnosis.

Costs beyond the purchase price — Maureen Cropper et al., 2024
What was studied: Modelled health and economic burden using epidemiological associations and 2015 exposure data from 38 countries, covering roughly one-third of the world’s population.
The model considered BPA and heart disease or stroke, DEHP and deaths among adults aged 55–64, and prenatal PBDE exposure and children’s IQ. Estimated health costs totalled about $1.5 trillion in 2015 purchasing-power-parity dollars.
Keep in mind: This is a model dependent on causal and economic assumptions. It is not a current Australian cost estimate, a family’s expected bill or evidence that a named product caused disease.

Plastic’s wider social costs — Nancy Lauer et al., 2025
What was studied: University report synthesising existing estimates of social costs across the plastics life cycle.
The report estimates annual US social costs of US$436 billion–US$1.1 trillion in 2025 dollars, combining health costs with climate, disposal and other impacts. Health costs account for most of the total.
Keep in mind: This is not a global environmental-only figure. It draws partly on the same research as the Cropper paper, so the totals should not be added together.
