Abstract This study analyzed arsenic speciation in livestock meat and viscera from Jiaxing and assessed the health risks associated with inorganic arsenic (iAs) exposure. Total arsenic and ten arsenic species, including organoarsenicals and their degradation products, were determined in chicken and pork tissues. Results showed total arsenic levels complied with standards, with chicken liver having the highest concentrations (105.65 μg/kg total arsenic; 41.78 μg/kg iAs). DMA and As(III) dominated, DMA comprised 62.59 % in chicken kidney and 50.94 % in pork kidney, As(III) accounted for over 36 % in both chicken liver and pork liver. ASA (31.33 μg/kg) in chicken muscle suggested potential illegal or historical use; ROX, NPAA, and CBAs were undetected in any of the samples. Margin of exposure (MOE) values all exceeded 1, indicating a low health risk. Dietary iAs exposure from meat and viscera in Jiaxing poses minimal risk, but cumulative multi-source effects require attention. Strengthened regulation of arsenic-containing feed additives is advised to prevent banned substance misuse.
