Abstract
This systematic review examined evidence linking climate-related changes in pest dynamics with pesticide use, livestock exposure pathways, and pesticide residues in animal-derived foods. Scopus, Web of Science Core Collection, PubMed/MEDLINE, and ScienceDirect were searched for studies published from 2000 to 2025. Of 2,230 records identified, 92 studies met the eligibility criteria. Owing to substantial heterogeneity, evidence was synthesized narratively with descriptive study-reporting frequencies. Increased pesticide application was reported in 63 studies (68.5%), and feed contamination was the most frequently reported livestock exposure pathway (73 studies; 79.3%). Residues were reported in studies of milk, meat, and eggs, but matrix-specific detection percentages were not calculated because reliable denominators were unavailable. Overall, the evidence supports an association-based climate-pest-pesticide-livestock-food framework rather than a complete causal sequence. The principal evidence gap is the scarcity of studies evaluating the full pathway within a single empirical design.
