Are phthalates in food packaging a health risk?

What's actually in it

Food packaging is rarely just a container. It is often made of plastics that break down over time. When you store or heat food in these materials, they can shed tiny pieces called microplastics and nanoplastics. These particles can get into your food and eventually into your body.

Beyond the plastic itself, these materials act as carriers for other substances. While the current science highlights the danger of plastic particles, it is clear that these containers are not inert. They interact with your food and can transfer unwanted materials directly into your meals.

What the research says

A 2026 study in Food Res Int highlights that microplastics and nanoplastics are commonly found in liquid foods. These particles migrate from packaging into what you eat and drink, creating potential health risks that scientists are still working to fully map out.

The risks are not the same for everyone. A 2026 study in Environ Pollut found that microplastics accumulate in the food web and pose a higher risk for children. Because children are still growing, their bodies are more sensitive to these environmental contaminants.

Furthermore, a 2026 study in Food Chem assessed the contamination levels in packaged frozen seafood. The peer-reviewed research confirms that microplastic contamination is a widespread issue in modern food packaging. This means that every time you use standard plastic packaging, you are likely exposing yourself and your family to these materials.
