Resumen: Styrene is an organic compound widely used in the production of plastics for food packaging. The main aim of this review is to compile information on the risks associated with exposure to styrene, evaluating and comparing studies that address the methods for determining the styrene migration, the factors that affect such migration and the consequences of this substance on Human Health.
Current evidence indicates that styrene levels in food generally remain within regulatory limits; however, cumulative exposure from multiple sources, including food packaging and the environment, requires further investigation. Packaging materials and food processing methods can influence styrene migration, underscoring the need for context-specific assessment. Continuous monitoring and periodic updates to safety standards are essential to ensure long-term consumer protection. Moreover, transitioning towards a Circular Economy, through sustainable reuse and recycling of plastics, is critical for minimizing styrene release and achieving safer, more environmentally friendly food packaging solutions.
