Long-Term Exposure to Aflatoxins and Early Onset of Cognitive Decline: A Scientific and Policy Analysis Abstract Aflatoxins, toxic secondary metabolites produced by Aspergillus species, are well-established hepatotoxins and carcinogens. However, emerging evidence suggests that chronic exposure may also contribute to neurotoxicity and early-onset cognitive decline. This paper synthesizes current knowledge on the mechanisms linking aflatoxin exposure to neurological impairment, including oxidative stress, neuroinflammation, and disruption of the gut–brain axis. It further explores epidemiological patterns in high-exposure regions and evaluates policy gaps in food safety systems. The paper argues that aflatoxin exposure represents an underrecognized risk factor for neurodevelopmental deficits and premature cognitive aging, particularly in low- and middle-income countries. 1. Introduction Aflatoxin contamination is a persistent public health issue in many parts of Africa, part...

Quality of Livestock Feeds, Aflatoxins, and Other Toxins: Implications for Consumers of Livestock Products—A Scientific and Policy Analysis Abstract Livestock feed quality is a critical determinant of food safety, animal health, and human well-being. Contamination of feeds with aflatoxins and other toxic compounds—such as fumonisins, pesticide residues, and heavy metals—poses significant risks across the food chain. This paper examines the occurrence, mechanisms of transfer, and health implications of feed-borne toxins in livestock products including milk, meat, and eggs. It integrates toxicology, animal science, and public health perspectives, with a focus on African production systems. The paper further evaluates regulatory gaps and proposes policy interventions aimed at reducing exposure risks and safeguarding food systems. 1. Introduction Livestock production systems depend heavily on the quality and safety of feed inputs. In many African countries, including Kenya, fee...

Acaricide Use in the Mara Region and Its Implications for Wildlife Populations and Conservation: A Scientific and Policy Analysis Abstract The widespread use of acaricides in livestock production across the Maasai Mara ecosystem has significantly improved tick control and livestock productivity. However, increasing evidence suggests that acaricide residues and misuse pose substantial risks to wildlife populations and conservation outcomes. This paper examines the environmental fate, ecological impacts, and conservation implications of commonly used acaricides in the Mara region. It integrates toxicology, wildlife ecology, and socio-economic drivers to assess how chemical tick control strategies influence biodiversity, trophic interactions, and ecosystem stability. The paper concludes with policy recommendations aimed at balancing livestock health with conservation priorities. 1. Introduction The Mara-Serengeti ecosystem is one of the most biologically diverse regions in Af...

Downstream Implications of Acetamiprid Decay on Fish Production in Lake Victoria : A Scientific and Policy Analysis Abstract Acetamiprid, a neonicotinoid insecticide widely applied in African agriculture, undergoes environmental degradation into metabolites that may retain biological activity and persistence in aquatic systems. In the Lake Victoria basin, diffuse agricultural runoff introduces both parent compounds and transformation products into freshwater ecosystems. This paper examines the downstream implications of acetamiprid decay on fish production through integrated analysis of environmental chemistry, aquatic toxicology, and fisheries ecology. Evidence suggests that chronic exposure to acetamiprid metabolites contributes to endocrine disruption, trophic instability, and reduced fish reproductive success. The study highlights significant policy gaps and proposes an integrated basin-level regulatory framework. 1. Introduction Lake Victoria is central to East Africa’...
