“Fresh food for example can be plastic-free when it’s picked or caught but contain plastics by the time it’s been handled, packaged, and makes its way to us,” Nelis said in a media release.
“Machinery, cutting boards, and plastic wrapping can all deposit micro and nano plastics onto our food that we then consume. This study highlights the need to understand what plastic could end up in food to manage food safety and security.”

Plastics can also enter the agriculture system through biosolids from wastewater treatment, which can contain plastic particles that could change soil structure over time and affect crop production.

Nelis said more research was needed into the health effects of micro and nanoparticles on humans and their impact on food safety and security.
“The key missing information in determining safe levels of microplastics. We currently don’t know exactly what the microplastic flux through the food system is or which levels can be considered safe,” he said.
