Effects of Microplastics on Animal Health and Nutrition Year 2024, Volume: 21 Issue: 2, 72 - 77, 02.08.2024
Summary
This review examined the effects of microplastics on animal health and nutrition, summarizing experimental evidence across livestock, poultry, and aquaculture species and identifying pathways by which dietary plastic exposure affects growth and feed efficiency.
Macro plastics are defined as plastics that are larger than 20 cm. Plastics that measure between 5-20 cm are referred to as mesoplastics, while those between 1-5 mm are known as large microplastics. Plastics that measure between 1-1000 μm are called small micro plastics, and those that are smaller than 1000 μm are referred to as nano-plastics. Microplastics are particles that result from the degradation of plastic products or are specifically produced in the form of small pieces. They are considered to be less than 5 μm in size. Micro plastics have come to the fore in re-cent years and are pollutants of major concern to the environment. Plastic materials are commonly used on farms, but they can have negative effects on farm animals. Ruminants such as cattle, sheep and goats require cellulolytic micro-organisms for fiber digestion in their diet. The micro biota of the digestive system varies according to dietary habits. The digestive system and other organs can be adversely affected by sudden changes and damage to the micro biota. The ingestion of large plastic materials causes rumen complications such as rumen atony, indigestion and tympani in livestock. Ingested plastic fragments degrade in the digestive tract, increasing the number of small particles likely to be ingested. In a recent study, the presence of low-density micro plastics in sheep feces suggests that animals can ingest micro and macro plastics from their environment and feed. The increase in demand for the consumption of plastics worldwide is increasing the production of plastics. This situation causes the presence of micro plastics to increase rap-idly day by day. Even if the production of plastics decreases, the continuous degradation of plastic waste in the earth will continue the formation of micro plastics and cause environmental pollution. The effects of microplastics in our coun-try should be investigated by conducting detailed studies from the perspective of veterinary medicine.

Effects 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 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.
Presence 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.
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.
