The study provides detailed molecular evidence of how microplastics can damage the digestive health of poultry, which may have implications for food safety.
The impact of polystyrene nanoplastics on the chicken gut and liver: Based on transcriptomics and microbiomics
Researchers fed polystyrene nanoplastics to chickens for 21 days and found that the particles triggered inflammation and oxidative stress in the gut and liver, damaged the intestinal lining, and disrupted the gut microbiome — with some effects persisting even after exposure stopped. Because poultry is a major protein source for humans globally, these findings raise concerns about nanoplastic contamination in the food supply.
Co-exposure to Polyethylene Fiber and Salmonella enterica Typhimurium Alters Microbiome and Metabolome of in vitro Chicken Cecal Mesocosms
An in vitro study using chicken cecal bacteria found that co-exposure to polyethylene microplastic fibers and Salmonella enterica Typhimurium altered the gut microbiome composition and metabolite profiles compared to either exposure alone, lowering the Firmicutes-to-Bacteroidetes ratio. The results suggest microplastics can modify how poultry gut bacteria interact with foodborne pathogens, with potential implications for food safety and human health through the food chain.
Co-exposure to polyethylene fiber and Salmonella enterica serovar Typhimurium alters microbiome and metabolome of in vitro chicken cecal mesocosms
Researchers studied how polyethylene microplastic fibers interact with Salmonella bacteria in the gut environment of chickens using an in vitro model. They found that co-exposure altered the microbial community composition and metabolic activity in ways that could favor pathogen survival. The findings raise concerns that microplastic contamination in poultry feed could potentially increase the risk of Salmonella infections in flocks and, ultimately, in the human food supply.
Microplastic Contamination in Commercial Poultry Feed and Edible Chicken Tissues: An Emerging Environmental Concer
Researchers investigated microplastic contamination in commercial poultry feed and edible chicken tissues from farms near Rajshahi City, Bangladesh, finding microplastics in all samples tested. Feed samples contained an average of 18.7 microplastic particles per gram, while chicken meat averaged 0.95 particles per gram, with fibers being the dominant shape. The study raises concerns about the transfer of microplastics from feed to edible poultry tissues as a pathway for human dietary exposure.
Microplastic pollution in eggs impairs chick development by disrupting yolk sac function and intestinal homeostasis
Researchers detected microplastics in all commercial chicken eggs tested (average 17 μg/g), confirmed maternal transfer by finding polystyrene and polyethylene in all ovarian follicles, and showed that injecting polystyrene nanoplastics into yolk sacs disrupted yolk sac function and intestinal development in chicks.

This study examined how microplastic ingestion affects gut microbiome diversity and composition in an animal model, finding that microplastic exposure alters microbial community structure in ways that may impair digestive and immune function.
Chronic exposure to polyethylene terephthalate microplastics induces gut microbiota dysbiosis and disordered hepatic lipid metabolism in mice
Researchers found that mice exposed to PET microplastics (the type commonly found in plastic bottles) over 17 weeks developed liver damage, including fat buildup, oxidative stress, and cell death. The study revealed that the damage was driven by changes in gut bacteria that altered lipid metabolism, and when researchers depleted the gut bacteria, the liver damage was reduced. This suggests the gut microbiome plays a key role in how microplastics cause harm to internal organs.
Phthalates released from microplastics inhibit microbial metabolic activity and induce different effects on intestinal luminal and mucosal microbiota
Researchers used a simulated human gut model to show that intestinal microbiota accelerates the release of phthalate plasticizers from microplastics, and these released phthalates inhibit microbial metabolic activity and differentially affect luminal versus mucosal gut bacteria.
