Prevalence of Plastic and Hardware Foreign Bodies among Goats at Malawi Markets

Simple Summary Goat smallholdings are common in both rural and urban areas of Malawi, and are kept as a food source and as investments to improve livelihoods. However, goats are known to forage on indigestible items that can negatively impact health and lead to a loss of productive performance. To date, no studies have estimated the prevalence of pollution among Malawi goats despite issues with waste management. To this end, we sought to survey the frequency of plastic and other indigestible foreign bodies among goats slaughtered by informal market butcher stands in five districts spanning Malawi. Most of the butchers surveyed identified plastic during slaughter (80%) while almost half (45.3%) identified other indigestible objects (hardware). Plastic was found by butchers in all districts and across rural and urban settings. While being less common than plastic, the hardware noted by butchers included sharps such as needles and bicycle spokes. When purchasing, butchers do consider animal health important, but 70.7% consider injury status as less or not important. Overall, this study highlights the issues of pollution among smallholder goats and demonstrates the need for further study to address the impacts of pollution on animal health and knock-on impacts on smallholder livelihoods.Abstract Smallholder goat production plays a major role in rural livelihoods and food security in Malawi, but suffers from drastic and unpredictable production losses. While goat production is closely linked to small-scale local markets for slaughter and butchering, the perspectives of butchers and their potential as a source of animal health information are largely untapped. Butchers can provide insights into goat health status at slaughter as well as issues that go unseen before slaughter, such as the presence of indigestible foreign bodies (IFBs). IFBs include solid materials such as plastics and hardware (metals, stones, and other hard objects) that cause foreign body syndrome and can lead to impaction, oedema, malnutrition, and death. To estimate the presence of IFBs, 150 market stand butchers were surveyed across five districts in Malawi, focusing on a distinction between hardware and single-use plastics, which are still widely present in Malawi despite bans on production. Most butchers found plastic IFBs (80.7%), with over half (56.7%) reporting plastic IFBs recently among the past five slaughters. Hardware IFBs were less common, reported by 45.3% of butchers. While some butchers commented on the impact of IFBs on meat quality metrics ex-post, the majority observed no differences. While butchers unanimously considered health to be an important characteristic when sourcing goats, 70.7% consider injury status to be less important or not important. Overall, this study highlights the issue of anthropogenic waste pollution on goat production in Malawi and demonstrates the potential for the surveillance of goat health at market.
