The results of new scientific lab testing reveal that high levels of microplastic particles are released from baby bottles during formula preparation. That means that infants and young children may ingest unwanted microplastics along with their formula.
Study findings overview
The research team tested 10 baby bottles that account for nearly 7 out of 10 bottles used around the world to feed infants, and found that heat was closely tied to the release of particles.
The hotter the liquid inside a baby bottle, the more microplastics are released.
Bottles made of polypropylene plastic released up to 16.2 million microplastic particles per liter of liquid when sterilized and then exposed to warm 158-degree Fahrenheit water. Warmer water at 203 degrees Fahrenheit caused an even greater release of microplastic particles, as much as 55 million particles per liter.
“The number of detected microplastic particles appears very high. However, we…
