Researchers tested 50 packaged nonalcoholic beverages in Hong Kong and found microplastics in every single one, with an estimated annual intake of about 6,200 microplastic particles per person from beverages alone. The contamination came from both the packaging materials and airborne particles during manufacturing, showing that everyday drinks are a meaningful source of human microplastic exposure.
Food Contamination with Micro-plastics: Occurrences, Bioavailability,Human Vulnerability, and Prevention
The study reviews the occurrence, bioavailability, and potential health impacts of microplastics in food, noting that contamination has been detected in foodstuffs and beverages worldwide. Researchers highlight that current data on dietary microplastic exposure remains insufficient for comprehensive risk assessment, and call for standardized methodologies to better evaluate the threat to human health.
Chemical Analysis of Microplastics and Nanoplastics: Challenges, Advanced Methods, and Perspectives
This review covers the latest laboratory methods for detecting and measuring microplastics and nanoplastics in environmental samples like water, food, and air. Identifying these tiny particles is extremely challenging because they vary enormously in size, shape, and plastic type, and concentrations can differ by billions of times between samples. Better standardized detection methods are essential for accurately understanding how much microplastic humans are actually exposed to.

The study recommends advanced filtration, alternative packaging materials, and stronger regulations as strategies to reduce plastic contamination in drinks.
Analytical method development and occurrence of microplastics from daily food containers
This study developed and optimized analytical methods for detecting microplastics in food containers and estimated human ingestion through this exposure pathway. The research supports the widely-cited estimate that people ingest about 5 grams of plastic per week, and provides improved detection methods for food safety monitoring.
MPs in drinking water and beverages: Concentrations, characteristics and implications for human exposure
Researchers reviewed 10 years of studies on microplastics in drinking water, bottled water, tea, coffee, and other beverages, finding that contamination levels vary widely by region, packaging type, and how hot the liquid gets. Children face disproportionately higher exposure relative to body weight, and the review highlights a critical need for standardized testing methods to better assess health risks from daily beverage consumption.
Synthetic microplastics in hot and cold beverages from the UK market: Comprehensive assessment of human exposure via total beverage intake
Researchers tested 155 common hot and cold beverages from UK stores and found microplastics in every single sample. Hot tea had the highest levels at about 60 particles per liter, and hot beverages consistently contained more microplastics than cold ones, suggesting that heat causes more plastic to leach from packaging. Based on typical UK drinking habits, the estimated daily microplastic intake from beverages alone was 3,432 to 6,864 particles per person.
