ClearMicroplastic in the farm animal derived food chain: The silent contaminants from farm to fork
Researchers reviewed five years of studies on microplastic contamination in animal-derived foods — including milk, meat, and eggs — finding that plastics enter livestock through ingestion and breathing, then end up in products consumed by humans. Once ingested, plastic particles can damage cell structures including mitochondria and the nucleus, potentially disrupting the digestive, reproductive, and nervous systems.
Microplastics in Farmed Animals—A Review
This review summarizes research on microplastic contamination in farmed animals including fish, cattle, and poultry, finding that microplastics have been detected in their intestines, liver, kidneys, lungs, and reproductive organs. The particles disrupt gut bacteria, cause tissue damage, and carry toxic chemicals and pathogens. Since these animals are raised for human consumption, microplastics in livestock represent a direct pathway for plastic contamination to reach people through their diet.
