Summary

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.

This study aimed to determine the prevalence of Bali cattle rumen containing plastic waste and its impact on tissues and health risks. A total of 100 Bali cattle were investigated after being slaughtered at several traditional slaughterhouses in Denpasar City. Rumen samples were examined for any plastic waste, meanwhile blood, liver, kidney, lungs, spleen, intestine, and myocardium were collected for evaluation of heavy metals content and histopathological examination. The heavy metal measurement was performed using the atomic absorption spectrophotometry (AAS) method. Those tissues for histopathological examination were fixed in buffer neutral formalin (BNF) and then evaluated using hematoxylin-eosin (HE) staining. The results of the examination reported 9 rumens (9%) containing plastic waste. The hematological profile showed leucocytosis and the content of lead (0.841 ± 0.522 ppm). Histopathological changes in the liver, kidneys, lungs, spleen, and intestine, were found in various types of degeneration, inflammation, and mild necrosis. In conclusion, the prevalence of plastic waste in the rumen of Bali cattle was 9%, with leucocytosis, lead content was 0.841 ± 0.522 ppm, and various histopathological lesions such as congestion, inflammation, and fatty degeneration in parenchymous tissues.

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.

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 Poor Municipal Waste Management on Ruminant Livestock

A study at an abattoir in Maiduguri, Nigeria found that nearly three-quarters of examined cattle had ingested non-biodegradable waste, with plastics (mostly polypropylene and polyethylene) present in 95% of those cases. The findings highlight how poor municipal waste management in African cities allows plastic litter to reach livestock through open grazing, creating both animal welfare concerns and potential food safety issues when contaminated animals enter the human food chain.
