ClearEffects of Microplastics on Animal Health and Nutrition
This review summarizes the current understanding of how microplastic ingestion affects animal health across multiple species including livestock, poultry, and aquatic organisms. Researchers found that microplastics can cause inflammation, oxidative stress, and disruption of gut function in animals, with smaller particles posing greater risks due to their ability to cross biological barriers. The study suggests that microplastic contamination in feed and water sources is an emerging concern for animal agriculture and nutrition.

Impact of Microplastics and Nanoplastics on Livestock Health: An Emerging Risk for Reproductive Efficiency
This review summarizes the growing evidence that microplastics and nanoplastics harm livestock reproductive systems through oxidative stress, hormone disruption, and organ damage. Farm animals are particularly important because contaminants in their bodies can transfer to humans through meat, milk, and eggs. The review warns that microplastic accumulation in livestock could create a hidden food safety risk through biological amplification up the food chain.
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.
The impact of polyethylene microplastics exposure on the, growth performance, reproductive performance, antioxidant capacity, and intestinal microbiota of quails
Researchers fed quails different levels of polyethylene microplastics and found that exposure harmed their growth, reproduction, and gut health. The microplastics reduced antioxidant defenses and disrupted the balance of beneficial bacteria in the birds' intestines. Since poultry is a major food source for people, microplastic contamination in farm animals raises concerns about indirect human exposure through the food chain.
Micro- and nanoplastic contamination in livestock production: Entry pathways, potential effects and analytical challenges
This review evaluates how micro- and nanoplastics enter livestock production systems through plastic mulching, waste fragmentation, and water runoff. The study suggests that these plastic particles can accumulate in livestock animals and potentially transfer up the food chain, though standardized analytical methods and comprehensive studies on livestock health effects are still lacking.
Impact of microplastic intake via poultry products: Environmental toxicity and human health
This review examines how microplastics enter the human diet through poultry products like chicken meat and eggs. Microplastics from contaminated feed, water, and farm environments accumulate in poultry tissues and are then passed to consumers. The study highlights that this food chain transfer represents an underappreciated pathway of human exposure, with potential risks including inflammation, gut disruption, and accumulation of toxic chemicals carried by the plastic particles.
A critical review of microplastic pollution in breeding industry: Sources, distribution, impacts, and characterization techniques, mitigation strategies and future research directions
This review provides a comprehensive overview of microplastic pollution in the breeding and livestock industry, covering sources, distribution patterns, and potential impacts on animal and human health through the food chain. Researchers identified key gaps in current understanding of how microplastics move through farming environments and accumulate in livestock. The study calls for more systematic research to help the industry develop strategies for preventing microplastic contamination.
From farm to fork: Microplastic contamination in the meat and dairy supply chain
This review evaluated the prevalence, pathways, and risks of microplastic contamination in meat and dairy products across the supply chain. Researchers found persistent microplastic presence in livestock tissues, poultry organs, processed meats, raw milk, and commercial dairy products, with common polymers including polyethylene and polypropylene, raising concerns about food safety from farm to fork.
Animal exposure to microplastics and health effects: A review
Researchers reviewed how microplastic exposure affects animals across terrestrial and aquatic environments, finding that species suffer physical harm, chemical contamination from pollutants that stick to plastic surfaces, inflammation, and behavioral changes. Because microplastics accumulate up the food chain, the review warns that animals entering the human food supply may carry these particles into our bodies.
The Environmental Pathways and Veterinary Health Implications of Microplastics and Nanoplastics: A Comprehensive Evaluation of Emerging Contaminants from a One Health Perspective
This review examines how microplastics and nanoplastics enter animal-based food products including milk, poultry meat, and eggs, and what this means for both veterinary and human health from a One Health perspective. Researchers found that these particles have been documented in various livestock products, but significant gaps remain in understanding contamination from raw, unprocessed sources. The study emphasizes the need for standardized detection methods and farm-to-fork monitoring to identify real contamination sources and develop effective control strategies.
Microplastics in Terrestrial Domestic Animals and Human Health: Implications for Food Security and Food Safety and Their Role as Sentinels
This review examines how farm animals and pets are exposed to microplastics, and what that means for human health. Livestock can accumulate microplastics in their tissues during their lifetime and from processing equipment, meaning meat and dairy products may contain plastic particles. Pets like cats and dogs, who share our living spaces, could serve as early warning indicators for the levels of microplastic exposure that humans face at home.
Quail Meat Under Threat: Hidden Microplastics Pose Risks to Public Health and Environment
Researchers analyzed tissues and organs of quails that had died naturally and found microplastics in the form of filaments, fragments, and films throughout the digestive system and edible meat. Polyethylene and polyvinyl stearate were the most commonly detected polymer types, with the highest concentrations found in intestinal contents. The presence of microplastics in breast and leg meat raises concerns about human dietary exposure through poultry consumption.
The potential effects of microplastics on human health: What is known and what is unknown
This review summarizes what is currently known about how microplastics might affect human health, noting that while contamination is widespread in food, water, and air, direct evidence of harm in humans is still limited. Studies in animals and cell cultures suggest microplastics could trigger immune responses, cause inflammation, and affect reproduction and development. The authors call for more rigorous clinical studies to determine whether the levels of microplastics that people actually encounter pose real health risks.
First Report on Microplastics Quantification in Poultry Chicken and Potential Human Health Risks in Pakistan
Researchers in Pakistan found microplastics in the crops and gizzards of poultry chickens from eight different farms, identifying over 1,200 particles across 24 samples. Fibers were the most common type, likely coming from plastic feed bags and the farm environment. Since chicken is a major protein source, this study reveals another pathway through which microplastics may enter the human diet.
