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 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.
Microplastics in animal nutrition: Occurrence, spread, and hazard in animals
Researchers reviewed how microplastics — tiny plastic particles less than 5mm — move through the food chain and enter animals via contaminated food, water, and prey, potentially disrupting gut health, nutrient absorption, and hormonal function across fish, birds, mammals, and invertebrates. Because these effects can pass up the food chain, the review warns of human health risks from eating animal products contaminated with microplastics.
