Are plastic cutting boards safe for preparing baby food?
No. Plastic cutting boards shed microplastics that can cause metabolic and gastrointestinal disruption, according to peer-reviewed research.
What's actually in it
Plastic cutting boards are made of materials like polyethylene terephthalate (PET). Every time you use a knife on these boards, you create tiny cuts. These cuts release microplastics and nanoplastics directly into the food you are preparing for your baby.
These particles are not inert. They are foreign materials that end up in your baby's digestive system. Once ingested, these plastics can interact with the body in ways that disrupt normal health, as shown by a 2026 systematic review in Environ Health.
What the research says
A 2026 study in Drug Chem Toxicol found that even a single oral exposure to PET microplastics causes metabolic and gastrointestinal disruption. The study highlights that these effects are real and measurable.
The science is clear that these small particles pose significant questions regarding human health. A 2026 study in Part Fibre Toxicol emphasizes the need to understand the toxicity and potential health risks of these PET micro- and nanoplastics. When you prepare baby food on plastic, you are introducing these particles into your child's diet every single day.
