# Food Packaging Crisis: How Containers Contaminate Every Meal *Published by NonToxic.com Research Team | February 2025* Various food packaging containers with visible microplastic particles contaminating food Every meal you eat is potentially contaminated with microplastics from food packaging, processing equipment, and storage containers. Research reveals that **plastic food packaging is the primary source of microplastic contamination** in the food supply, with heated containers releasing **5-173 particles per sample** and packaging migration affecting virtually every packaged food product. ## The Invisible Contamination in Every Package Food packaging has evolved from simple protection to complex multi-layer systems designed for convenience, shelf-life extension, and marketing appeal. However, this evolution has created an unprecedented contamination crisis where plastic packaging continuously sheds microplastic particles into the food it's designed to protect. Unlike environmental contamination that affects foods during growth or processing, packaging contamination occurs at the point of consumption, delivering concentrated doses of microplastics directly to consumers with every packaged meal. ### The Scale of Packaging Contamination Recent research has documented the pervasive nature of packaging-related microplastic contamination: - **Plastic packaging** identified as the primary contamination source - **5-173 particles per sample** released from heated polystyrene containers - **Universal contamination** across all packaged food categories - **Processing equipment** contributing additional contamination - **Storage and transport** creating ongoing contamination opportunities ## Container Types and Contamination Levels Different packaging materials and container types show dramatically different levels of microplastic contamination, with some packaging posing significantly higher risks than others. ### Highest Risk Packaging Types #### Polystyrene Food Containers Polystyrene (PS) containers, commonly used for takeout food and food service, represent one of the highest sources of microplastic contamination.
