Microplastics in Small Ruminants I
AI summary Read the abstract
A study in Guayas Province, Ecuador, found microplastics in every sample collected from 200 sheep feces, water, and feed samples, with water origin and feed category as the primary sources of microplastic contamination in small ruminant farming.
The research work in the Province of Guayas (Ecuador) aimed to evidence the presence of microplastics in sheep based on the analysis of 200 samples divided between feces, sources of water, and diet types given. Different methods were applied for the different analyses. The findings were shocking, with microplastics found in every single sample. The most significant factors, such as water origin and feed category, were assessed, which indicated that they are both sources of pollution in sheep. Statistically, dependent and independent factors related with the contamination in these animals were detected. However, one of the biggest concerns is due to their omnipresence, microplastics have now become an enormous problem for both human health and the environment, in part because of their slow disintegration. The build-up of the microplastics is a significant issue as the plastic items typically have a very short useful life and are generally single use, yet they remain in the environment for years without breaking down.

Presence of microplastics in small ruminants from pastoral systems on the Ecuadorian coast
AI summary Read the abstract
Researchers testing goats and sheep in coastal Ecuador found tiny plastic particles (microplastics) in every single animal they checked — mostly plastic fibers, likely from farm materials like textile waste or degrading plastic tarps. This matters because these are farm animals raised for meat and milk, so if microplastics are building up in their bodies, they could potentially be making their way into the food we eat too — though more research is needed to confirm exactly what these particles are and how they might affect us.

Researchers assessed microplastic contamination in water sources, feed types, and equine feces at two horse husbandry facilities in Guayas province, Ecuador, finding microplastics detectable in all sample types. Results showed 58 percent of river water samples and 66 percent of balanced feed samples contained microplastics, demonstrating that horses are exposed to plastic particles through multiple pathways in both their water supply and diet.
