Researchers from the Interdisciplinary Institute for Food Security (IIFS), Bangladesh Agricultural University, have reported widespread contamination of microplastics in bottled water and commercially packaged beverages, highlighting a growing challenge for food safety and public health.

The review study, led by Saydur Rahman with colleagues and students from Bangladesh Agricultural University, synthesizes global scientific evidence on the presence, sources, and potential health risks of microplastics in bottled water, soft drinks, juices, teas, and alcoholic beverages. The findings reveal that microplastic concentrations can range from a few to several hundred particles per litre, depending on beverage type, packaging material, and analytical method used.

According to the researchers, the primary sources of contamination include the degradation of plastic packaging materials such as PET bottles and polypropylene caps, bottling and processing environments, and contaminated source water. The study also indicates that children and frequent consumers of bottled beverages may experience higher exposure levels, raising particular concerns for vulnerable populations.

Experimental evidence suggests that ingested microplastics may contribute to inflammation, oxidative stress, and the transport of toxic substances within the human body. While definitive conclusions on long-term health impacts require further investigation, the growing detection of microplastics in human tissues underscores the urgency of addressing this emerging food safety issue.

The research team emphasizes the need for standardized detection methods, improved packaging practices, advanced filtration technologies, and stronger regulatory frameworks. They also highlight the importance of consumer awareness and coordinated international efforts to reduce microplastic contamination across the beverage supply chain.

This work reinforces the critical link between environmental pollution and food safety and calls for collaborative action to ensure safer drinking water and beverages for future generations.
