The sources and impact of microplastic intake on livestock and poultry performance and meat products: a review
This review examined how microplastics affect livestock and poultry health, productivity, and the safety of meat products. Researchers found that while lab experiments show microplastics can cause oxidative stress and inflammation at high concentrations, it remains unclear whether typical environmental exposure levels affect animal welfare or productivity. Microplastics were detected in animal tissues at levels that raise potential consumer safety concerns, though current detection methods are prone to contamination.
Effects of nano and microplastics on the reproduction system: In vitro and in vivo studies review
This review summarizes both lab and animal studies on how micro and nanoplastics affect the reproductive system in males and females. Evidence shows that microplastics can reduce sperm quality, damage ovaries, disrupt hormone levels, and even cross the placenta during pregnancy. The findings raise significant concerns about how widespread microplastic exposure might contribute to fertility problems and reproductive health issues in humans.
Farm animals as a critical link between environmental and human health impacts of micro-and nanoplastics
Researchers argue that farm animals — livestock exposed daily to microplastics and nanoplastics (tiny plastic particles under 5 mm and 1 micrometer, respectively) through contaminated feed, soil, and water — represent an understudied but critical link between environmental plastic pollution and human health risks through the food supply. The authors call for more research on how plastics transfer from agricultural environments through livestock into meat, dairy, and eggs consumed by people.
Understanding the impact of nanoplastics on reproductive health: Exposure pathways, mechanisms, and implications
This review summarizes existing research on how nanoplastics (tiny plastic particles smaller than one micrometer) affect reproductive health in animals and potentially humans. Studies show that nanoplastics can accumulate in reproductive organs including the placenta, and evidence from animal studies links exposure to hormone disruption, reduced fertility, and developmental problems. The authors highlight a significant knowledge gap about nanoplastic effects on human reproduction, despite growing evidence that these particles reach our reproductive systems.
Unraveling the threat: Microplastics and nano-plastics' impact on reproductive viability across ecosystems
This review summarizes research on how microplastics and nanoplastics affect reproduction across many species, from aquatic invertebrates to mammals including humans. In males, exposure leads to testicular damage, lower sperm quality, and hormone disruption; in females, it causes ovarian and uterine problems, inflammation, and reduced fertility. The evidence also shows these reproductive harms can be passed to offspring, raising serious concerns about long-term effects on human fertility.
Reproductive toxicity and related mechanisms of micro(nano)plastics in terrestrial mammals: Review of current evidence.
This review of terrestrial mammal studies found that micro- and nanoplastics induce reproductive toxicity through oxidative stress, inflammation, endocrine disruption, and DNA damage, affecting both male and female fertility. In males, effects include blood-testis barrier disruption and impaired spermatogenesis, while females show compromised oocyte maturation, ovarian fibrosis, and diminished ovarian reserve, with particles also capable of crossing the maternal-fetal interface.
Reproductive toxicity of micro- and nanoplastics
This review summarizes existing research on how micro- and nanoplastics harm reproduction across many species, from marine invertebrates to mammals. The particles can cause oxidative stress and hormone disruption, leading to reduced fertility, abnormal embryo development, and toxic effects that pass to offspring. The findings raise concerns that human reproductive health could be similarly affected given our increasing exposure to these particles.
Emerging insights into the impacts of heavy metals exposure on health, reproductive and productive performance of livestock
This review examines how heavy metals like lead, mercury, and cadmium accumulate in livestock through contaminated feed and water, causing oxidative stress, organ damage, reproductive problems, and reduced productivity. While focused on livestock rather than microplastics, the paper is relevant because microplastics can carry and concentrate heavy metals, potentially making their combined effects on the food chain even worse.
Connecting the Dots: Livestock Animals as Missing Links in the Chain of Microplastic Contamination and Human Health
This review highlights that farm animals are a missing link in understanding how microplastics move from contaminated soil and plants into the human food supply. Livestock can accumulate inhaled and ingested plastic particles, which may then transfer to people through meat, milk, and eggs. The authors call for standardized methods to measure microplastics in animal products to better understand this exposure pathway.
Microplastics and Reproductive Dysfunction in Animals
This review of existing research shows that tiny plastic particles called microplastics can build up in animal reproductive organs and cause serious fertility problems, including damaged sperm and eggs, hormone disruption, and birth defects. While these studies focused on animals, the findings are concerning for humans since we're also exposed to microplastics through food, water, and air. More research is needed to understand the long-term risks to human fertility and reproduction.
The Pressing Issue of Micro- and Nanoplastic Contamination: Profiling the Reproductive Alterations Mediated by Oxidative Stress
This review examined how micro- and nanoplastics affect reproductive health across aquatic and land-based organisms, focusing on oxidative stress as the primary damage mechanism. Researchers found that these plastic particles can reach the gonads through the bloodstream and even accumulate in human and mouse placenta, with harmful effects on sperm and egg development, embryo growth, and offspring survival. The severity of reproductive harm appears to increase with smaller particle sizes and longer exposure times.
