<p>Organohalogen compounds (OHCs) are persistent environmental contaminants that can pose health risks to both humans and animals. This study aimed to assess the contamination levels of OHCs in dry and wet pet foods sold in Japan and evaluate their potential health implications for companion animals.</p><p>Results indicated that OHCs were widely present in all types of pet foods analyzed, with dry foods generally exhibiting higher contamination levels than wet foods. Polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethanes (DDTs), chlordanes (CHLs), hexachlorocyclohexanes (HCHs), polybrominated diphenyl ethers (PBDEs), and decabromodiphenyl ethane (DBDPE) were detected in varying concentrations across different pet food types. The contamination profiles differed based on the raw materials and country of origin. Estimations of OHC concentrations from raw materials highlighted potential contamination sources beyond ingredient-related contributions, including the manufacturing process.</p><p>Moreover, risk assessments were conducted to evaluate the potential health risks posed by OHCs exposure through pet food consumption. While PBDEs, CHLs, and DDTs generally posed low risks, PCBs were found to be of concern, particularly in pet foods containing salmon as a primary ingredient. The results underscored the importance of considering the type of pet food and its raw materials when assessing exposure risks.</p>
