“Arsenic-based drugs are permitted in poultry production. Inorganic arsenic (iAs) causes cancer and maybe other adverse health outcomes. The contribution of chicken consumption to iAs intake, however, is unknown. Objectives: To characterize arsenic species profile in chicken meat and estimate bladder and lung cancer risk associated with consuming chicken produced with arsenic-based drugs. Methods: Conventional, conventional antibiotic-free, and organic chicken samples were collected from grocery stores in ten US metropolitan areas from December 2010 to June 2011. 116 raw and 142 cooked samples were tested for total arsenic, and 78 samples ≥10µg/kg dry weight underwent speciation. Conclusions: Conventional chicken meat had higher iAs concentrations than conventional antibiotic-free and organic chicken meat samples. Cessation of arsenical drug use could reduce exposure and the burden of arsenic-related disease in chicken consumers.”
