Analysis of residue of β-receptor agonists in livestock meat and products and assessment of exposure risk in Zibo city
Objective To understand the residual status of β-receptor agonists in livestock meat,liver and its products sold in the market in Zibo city of Shandong province from 2015 to 2022,and evaluate the exposure risk.Methods Livestock meat,liver and the products were randomly collected from different sales links for detecting the residue of β-receptor agonist,and the risk was evaluated by food safety index(IFS)method.Results In 187 samples,the β-receptor agonists were detected in 9 samples with a detection rate of 4.8％.The ractopamine was not detected,and the detection rate of clenbuterol,salbutamol and terbutaline was 3.7％,1.1％and 0.3％,respectively.There was no statistical difference(x2=0.015,P=0.902)between the detection rates of stores(4.7％)and farm produce fair(5.1％).The IFS of β-receptor agonist of clenbuterol,salbutamol and terbutaline was 0.507,0.033 and 0.033,respectively.Conclusions There are different degrees of residue ofβ-receptor agonist in livestock meat,liver and its products in Zibo city,but the exposure risk is low and acceptable.It is necessary to strengthen the supervision in the breeding process,carry out the β-receptor agonist monitoring,and establish a consultation mechanism for food safety risk to ensure that the exposure risk is minimized.
