More than a million microplastics are released during the preparation of infant formula

Following the publication of the results, an international team of researchers developed a set of recommendations for

preparing infant formula using plastic breastfeeding bottles that minimize the release of MP.

Led by Dr. Jing Jing Wang, professorJohn Boland and Professor Lieven Xiao of Trinity College Dublin, experts analyzed the potential for MP to be released from PP-IFBs during formula preparation according to international recommendations. They also assessed the effects of microplastics on 12-month-old babies in 48 countries and regions.

Key results

  • PP-IFB can allocate up to 16 million unitsmicroplastics and trillions of smaller nanoplastics per liter. Sterilization and exposure to high temperature water significantly increase the release of microplastics from 0.6 million to 55 million particles per liter when the temperature rises from 25 to 95 ° C.
  • Other polypropylene plastic products (kettles, lunch boxes) produce similar MP levels.
  • In accordance with the applicable guidelines forSterilizing Infant Feeding Bottles and Formulating Infants' daily exposure levels exceed a million microplastics particles. Oceania, North America and Europe have the highest levels of potential exposure to MF: 2,100,000, 2,280,000 and 2,610,000 particles per day, respectively.
  • The level of microplastics released from PP-IFB can be significantly reduced through modified sterilization and compounding procedures.

Given the global preference for PP-IBF, it is importantprevent the inadvertent formation of micro- and nanoplastics in infant formula, the researchers emphasize. Based on their findings, a team of scientists developed and tested recommendations for preparing an infant formula that will help minimize MP release.

Recommended Sterilization and Mixing Procedures

Sterilizing Infant Feeding Bottles:

  • Sterilize the bottle as recommended by the WHO and let cool.
  • Prepare sterilized water by boiling it in a non-plastic kettle / stove (such as glass or stainless steel).
  • Rinse the sterilized bottle with sterile water at room temperature at least 3 times.

Preparing baby formula:

  • Prepare hot water using a plastic-free kettle.
  • Prepare infant formula in non-plasticcontainer using water with a temperature of at least 70 ° C. Refrigerate to room temperature and transfer to a high quality plastic infant feeding bottle.

Standard Precautions:

  • Do not reheat the prepared mixture in plastic containers and avoid using microwave ovens.
  • In no case should you strongly shake the mixture in the bottle.
  • Do not use ultrasonic treatment to clean plastic baby feeding bottles.

However, experts note: Considering the prevalence of plastic products in everyday food storage and preparation, and the fact that every polypropylene product tested in the study (baby bottles, kettles, lunchboxes and noodle cups) produces similar MP levels, there is an urgent need for new technological solutions ...
