Study Finds Microwaving Plastic Baby Food Containers Releases Micro and Nanoplastics

Aug 22, 2023

A recent study conducted by researchers at the University of Nebraska-Lincoln has raised concerns about microwaving plastic baby food containers. The study found that heating baby food in plastic containers released a significant amount of micro- and nanoplastics into the food.

The research was prompted by concerns over plastic baby bottles leaching particles into formula. The team wanted to determine the extent to which plastic was being released into microwaved baby food. In just three minutes of microwaving, the study found that more than 4 million microplastic particles and over 2 billion nanoplastic particles were released per square centimeter.

The health effects of consuming these plastic particles are still unknown. To gain a better understanding, the researchers exposed tissue from infant kidney cells to the particles. They discovered that only 23% of cells exposed to a high dose of particles survived.

Experts, such as Judith Enck, a former EPA regional administrator, and president of the advocacy group Beyond Plastics, are calling for more proactive regulation from the FDA and the EPA. Enck emphasizes the importance of this study as a wake-up call for new parents and the need for aggressive action to address the issue.

Plastics are composed of polymers mixed with various chemicals, aiding them in retaining their shape. The process of microwaving, with the application of heat and hydrolysis, causes the plastic to degrade, creating small cracks that release microscopic plastic particles.

As the study concludes, it is crucial for individuals to be aware of the number of plastic particles present in their food, just as they are conscious of other nutritional aspects. With further research and regulation, a clearer understanding of the potential health risks associated with consuming these particles can be achieved.
