ClearPresence of Microplastics in Livestock Production: A Challenge for Animal Health and Sustainability
This review examines microplastic contamination in livestock production systems, summarizing evidence of microplastic presence in feed, water, and animal tissues, and discussing implications for animal health, food safety, and sustainability.
Development and application of a novel extraction protocol for the monitoring of microplastic contamination in widely consumed ruminant feeds
Researchers developed the first specialized method for detecting microplastics in cattle feed, including corn silage, hay, and mixed rations. They found that 50-60% of foreign objects in slaughtered cattle are plastic-based, and microplastics have been detected in ruminant tissues and feces. Since contaminated feed is a likely source, this detection method is important for understanding how microplastics enter the meat supply chain and potentially reach human consumers.
Detection and characterisation of microplastics in animal feed
Researchers detected microplastics in livestock and poultry feed samples collected from 12 different farms using infrared spectroscopy and thermal analysis. The study suggests that microplastic contamination in animal feed represents a potential pathway for these particles to enter the human food chain, raising concerns for food security.
Impact of Microplastics on Livestock: Sources, Exposure Pathways, and Physiological Consequences
This review examined how microplastics enter livestock systems through contaminated soil, water, and feed, and assessed the resulting risks to animal health, food safety, and agricultural sustainability. The review highlights that livestock exposure pathways are numerous and that microplastic contamination of the food chain is a growing concern.
Microplastics contamination in ruminant feeds of Northwestern Italy: a preliminary assessment
Researchers measured microplastic contamination in common cattle feeds at dairy farms in northwestern Italy, including corn silage, hay, and high-protein feedstuff. All feed types contained microplastics, with corn silage being the most contaminated at about 38 particles per gram. Since microplastics in animal feed can transfer into meat and dairy products, this finding highlights a potential route of human exposure through the food we eat.
The measurement of food safety and security risks associated with micro- and nanoplastic pollution
Researchers reviewed how micro- and nanoplastic pollution enters the human food chain through agricultural systems, raising concerns for food safety and security. They identified major gaps in our ability to assess the risks of plastic contamination in food and feed sources. The study calls for interdisciplinary approaches and better analytical methods to understand and address this growing challenge.
Microplastics in manure: Sources, analytical methods, toxicodynamic, and toxicokinetic endpoints in livestock and poultry
Researchers reviewed the occurrence of microplastics in livestock and poultry manure, finding hundreds to thousands of particles per kilogram depending on the animal, with plastic-contaminated feed and mulching films as the primary sources. Because manure is widely spread on farmland as fertilizer, it represents a significant — and underappreciated — pathway for microplastics to enter agricultural soils and ultimately the food chain.
Rapid detection of microplastics in feed using near-infrared spectroscopy
Researchers tested whether near-infrared spectroscopy could rapidly detect microplastic contamination in animal feed products like corn silage, hay, and soybean meal. The technique successfully identified polyethylene and polystyrene contaminants at concentrations as low as 1 milligram per gram of feed. The study offers a practical, non-destructive screening method that could help protect the food chain from microplastic contamination in livestock nutrition.
Microplastic Contamination in Aquafeed Ingredients Used as Protein and Carbohydrate Sources
Researchers analyzed microplastic contamination in common aquafeed ingredients used as protein and carbohydrate sources. They found that poultry by-products had the highest microplastic levels, with polypropylene being a dominant polymer type likely originating from packaging materials. The study identifies a pathway by which microplastics can enter aquaculture food chains through contaminated feed ingredients.

This review summarized current knowledge about microplastics in animal nutrition, covering their occurrence in feed ingredients and water, routes of exposure in livestock and poultry, and potential physiological and metabolic effects on animal health.
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.
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.
Microplastic assessment in aquaculture feeds: Analyzing polymer variability across commercial fishfeeds from three continents
Researchers assessed microplastic contamination in commercial aquaculture feeds, detecting particles across multiple feed types and suppliers and characterizing polymer variability, which may introduce plastics into farmed fish.
Quantitative and Qualitative Assessment of Microplastics in Drinking Water, Raw Materials, and Animal Feed Additives
Researchers assessed microplastic contamination in drinking water, feed ingredients, and complete diets at two dairy farms in Iran. The study found large numbers of microplastics of varying sizes and colors in feedstuffs, estimating that each cow ingests over 5,000 microplastic particles daily through their feed, raising concerns about potential transfer through the food chain.
