Microplastic in milk and dairy products: Research quality, abundance, sources, and transfer mechanisms
AI summary Read the abstract
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 (MPs), as emerging contaminants, have been widely detected in milk and dairy products. However, current studies lack systematic evaluation regarding data reliability, variations in MPs abundance across different dairy products, and the underlying sources and transfer mechanisms. This review applies an experimental quality assurance and quality control scoring to assess the quality of existing literature and identifies common methodological issues in milk and dairy product research. Evidence from published studies reveals varying degrees of MPs contamination from raw milk to milk powder, with the latter exhibiting the highest levels. To clarify the sources of MPs, this review investigates potential contamination pathways during packaging, processing, transportation, and farm environment. Further analysis indicates that MPs can enter dairy cattle through drinking water, feed, air, and dermal exposure, subsequently reaching the mammary gland via blood circulation. Once internalized by mammary epithelial cells, MPs may be secreted into milk. This review specifically highlights the long-overlooked but critical transfer pathway of MPs from environmental exposure through dairy cattle to raw milk. By elucidating this key contamination route, the study provides a theoretical foundation and research direction for risk assessment and mitigation strategies related to MPs in dairy products, offering valuable insights for ensuring milk quality and food safety.

Microplastics in Dairy Products: Occurrence, Characterization, Contamination Sources, Detection Methods, and Future Challenges
AI summary Read the abstract
Researchers reviewed 17 studies on microplastic contamination in milk and dairy products and found concentrations ranging from undetectable to over 10,000 particles per kilogram, with baby milk powder showing the highest levels. The most common plastics found were polyethylene, polypropylene, polyamide, and polyester, including some types considered harmful to human health. The study highlights that dairy products are particularly susceptible to microplastic contamination from packaging, processing equipment, and the environment.

Researchers tested milk, mozzarella cheese, yogurt, and cream products (12 packages, 36 samples total) for microplastics using microscopy and spectroscopy. Microplastic particles, mostly fragments, were found in all samples, with locally or regionally produced items showing higher levels than imported ones. Plastic types detected included polyethylene, polypropylene, polyester, polystyrene, and polycarbonate, suggesting contamination from processing equipment and packaging.
