Mean total arsenic concentrations in chicken 1989-2000 and estimated exposures for consumers of chicken.

Abstract

The purpose of this study was to estimate mean concentrations of total arsenic in chicken liver tissue and then estimate total and inorganic arsenic ingested by humans through chicken consumption. We used national monitoring data from the Food Safety and Inspection Service National Residue Program to estimate mean arsenic concentrations for 1994-2000. Incorporating assumptions about the concentrations of arsenic in liver and muscle tissues as well as the proportions of inorganic and organic arsenic, we then applied the estimates to national chicken consumption data to calculate inorganic, organic, and total arsenic ingested by eating chicken. The mean concentration of total arsenic in young chickens was 0.39 ppm, 3- to 4-fold higher than in other poultry and meat. At mean levels of chicken consumption (60 g/person/day), people may ingest 1.38-5.24 microg/day of inorganic arsenic from chicken alone. At the 99th percentile of chicken consumption (350 g chicken/day), people may ingest 21.13-30.59 microg inorganic arsenic/day and 32.50-47.07 microg total arsenic/day from chicken. These concentrations are higher than previously recognized in chicken, which may necessitate adjustments to estimates of arsenic ingested through diet and may need to be considered when estimating overall exposure to arsenic.

Arsenic residues in broiler meat and excreta at arsenic prone areas of Bangladesh

“…Arsenic concentrations in animal tissues mainly depend on the dietary concentrations of arsenic, absorption rate and the homeostatic control mechanism of the body for arsenic (Doyle and Spaulding, 1978). In accordance with our study, variable concentrations of arsenic in chicken tissues under natural condition were reported by other investigators (Lasky et al, 2004;Mariam et al, 2004;Uluozlu et al, 2009). Conversely, Gacnik and Doganoc, (2000) did not find arsenic residue in meat, liver and kidney samples of poultry during 1994-1998 in Slovenia.…”

“…However, Wallinga (2006) found low or nondetectable levels of arsenic in certified organic and other "premium" brands, where the use of arseniccontaining feed additives were either legally prohibited or claimed not to have been used. Arsenic residue of skin> liver> lung> kidney> thigh muscle of broiler chicken is some extent similar as reported earlier (Lasky et al, 2004;Mariam et al, 2004). Highest arsenic residue obtained in broiler skin could not be compared due to lack of information.…”

Protective Role of Spirulina and Vitamin E against Arsenic Toxicity in Rats

“…Arsenic can enter into food chain (Ulman et al, 1998) causing wide spread distribution throughout the plant and animal kingdoms. The detection of arsenic in milk and meat is a new finding (Lasky et al, 2004;Awal, 2007). Poultry meat and feces may also contain arsenic because they also drink tube-well water especially in urban areas and at farm levels.…”

Impacts of Geochemical and Environmental Factors on Seasonal Variation of Heavy Metals in a Coastal Lagoon Yucatan, Mexico

“…Thus wastewater could be permeating downward through the karst and contaminating the aquifer. Importantly, these farms use industrial animal feeds that include As, which increases the absorption of nutriments and promotes faster growth (Lasky et al 2004). Also, as in the case of Cr, a redox change could be taking place.…”
