    Abstract:

    Objective To investigate the pollution of heavy metals in chicken, eggs and chicken viscera in Anhui province, and to provide a basis for food safety risk monitoring and dietary guidance.Methods Chicken, eggs, chicken liver and gizzard were randomly sampled around the cities in Anhui Provinceof in 2019. Heavy metal element arsenic (As), lead (Pb), cadmium (Cd), chromium (Cr), mercury (Hg) contents were detected. Health risk was calculated combining the exposure levels of heavy metals and the Chinese residents’ food consumption survey data.Results The detection rates of heavy metals in chicken, egg, liver and gizzard samples were different, and the qualified rate was 100%. The contents of the same heavy metal (except Pb) in chicken, egg, chicken gizzard and chicken liver were significantly different (P<0.05), and the contents of different heavy metal were significantly different (χ2=17.13, P<0.05). The content of heavy metals in viscera was higher than that in chicken and eggs, and Cr content was the highest, followed by Pb. The exposure of heavy metals in chicken, eggs and chicken offal in Anhui province was far lower than the health guidance value.Conclusion The accumulation capacity of heavy metals in chicken, eggs and chicken viscera in Anhui Province is different, and heavy metals are more easily accumulated in viscera. The content of heavy metals in chicken, eggs and viscera in Anhui Province is low, the dietary exposure of the population is low, and the risk to human health is relatively small.
