This review examines the presence of microplastics in milk and dairy products, the analytical separation methods used to detect them, and potential health effects associated with dairy-sourced microplastic exposure. The authors discuss how plastics used in dairy packaging and processing equipment degrade into microparticles that contaminate food products, posing a global public health concern.
Microplastic in milk and dairy products: Research quality, abundance, sources, and transfer mechanisms
Researchers systematically reviewed evidence on microplastic contamination in milk and dairy products, applying quality control scoring to assess data reliability across studies. They found widespread MP contamination in dairy products with packaging and processing environments as primary sources, though inconsistent methods make quantitative comparisons difficult.
Microplastics in dairy products and human breast milk: Contamination status and greenness analysis of available analytical methods
Researchers reviewed the contamination of dairy products and human breast milk with microplastics, finding concentrations as high as 2,590 microplastic particles per liter, while also noting that most current detection methods are not environmentally safe or standardized. The findings call for stricter food safety regulations and greener analytical tools to track microplastic contamination in foods consumed from infancy.
Identification of Microplastics as Emerging Contaminant in Branded Milk of Tamil Nadu State, India
Researchers analyzed 16 samples from 13 branded milk products sold in Tamil Nadu, India, and found microplastic particles including polyethylene, polypropylene, and polyacrylamide in all samples. The particles were smaller than 500 micrometers, and contamination levels varied across brands. The findings suggest that plastic packaging may be a source of microplastic contamination in commercially available dairy products.
Microplastics contamination of milk and milk products in Bangladesh: Characterization, dietary exposure, and risk assessment
Researchers analyzed raw, branded, and processed milk samples in Bangladesh and found microplastic contamination in all types, with branded milk containing the highest average concentration at about 156 particles per 100 mL. Children showed higher dietary exposure than adults, and the dominant particles were small transparent fibers made of polymers including PTFE, PET, and nylon, highlighting the need for monitoring and regulation in the milk supply chain.
Identification and occurrence of microplastics in drinking water bottles and milk packaging consumed by humans daily
