Influencia Ecotoxicológico de Microplásticos en el Perfil Hematológico de Vacunos Brown Swiss Fistulados
Summary
Researchers measured Bisphenol A (BPA) — a plastic-associated endocrine disruptor — in the blood of cattle that were exposed to microplastics through their environment. The study found detectable BPA levels that disrupted blood parameters, raising concerns about how microplastic-associated chemicals accumulate in livestock and potentially transfer to humans through meat and dairy.
El Bisfenol A (BPA) compuesto químico empleado en la fabricación de plásticos. El uso cotidiano e inadecuada disposición de plásticos se ha incrementado de manera desproporcionada, la degradación de esta se genera partículas plásticas (microplásticos). El BPA pertenece a un grupo de sustancias denominadas disruptores endocrinos que tienen la capacidad de alterar las funciones y sistemas del organismo. El presente estudio determina si existe influencia de microplásticos en el perfil hematológico. Además, se cuantifica la concentración ecotoxicológico del BPA en microplásticos. Se aplicó la técnica de la degradabilidad In situ de las bolsas de nylon. Estas fueron efectuadas en tres vacunos estabulados de raza Brown Swiss, sexo macho, con fistulas permanentes en el rumen. Asimismo, se evaluó 16 parámetros del perfil hematológico tanto en el pre inducción y post inducción de microplásticos. Del Perfil Hematológico únicamente el parámetro Hematocrito (HCT), presento una variación media a nivel de significancia 0.05 en T2. Los valores en pre inducción (47.53 ± 1.29), post inducción (45.80 ±1.87) y concentración de BPA con valores inferiores a 0.01 mg/kg. Se puede presumir del resultado, que los microplásticos no influyen en el perfil hematológico de manera significativa, por el tiempo de exposición y cantidad de microplásticos.

Pathological Impacts Due to The Existence of Plastic Waste in Rumen of Bali Cattle
Researchers examined 100 Bali cattle slaughtered at traditional abattoirs and found that 9% had plastic waste in their rumens; those animals showed elevated blood lead levels and histopathological damage in liver, kidneys, lungs, spleen, and intestine. The findings raise food-safety concerns because livestock ingesting plastic waste accumulate heavy metals and sustain organ damage that could affect the quality of meat entering human food supply chains.
Fate of Plastics in Cattle Digestive Systems
Researchers detected plastic microfibers (0.5 to 15 mm) in the fecal matter of two herds of cattle on a college campus, demonstrating that cattle ingest microplastics at similar rates regardless of management differences, and raising concerns about plastic transfer through livestock products.
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.
Effect of microplastic on rumen metabolism.
This review examines how microplastics and plastic additives including bisphenols and phthalates accumulate in water, soil, and animal feed and transfer into animal products such as milk, meat, and eggs, raising food safety concerns. The authors discuss microplastics as disruptors of rumen metabolism in livestock.
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.
