Objective

To construct a Bayesian network risk assessment model to systematically quantify the risks of tetracycline, quinolone, β2-receptor agonist and sulfonamide drug residues.

Methods

The risk value was evaluated by expert scoring, and the initial model was established by using the information entropy weight method to obtain the prior probability. The Bayesian network warning model was established by importing the monitoring data through the expectation maximization algorithm (EM) of Bayesian network, and the risk prediction of the risk factors of animal residues was carried out.

Results

The overall risk probability of a province obtained by the Bayesian network model was (within the maximum detection limit): Low risk 74%, medium risk 16% and high risk 10%. The highest sensitivity of tetracycline was 0.37, which was the key risk factor; the risk of quinolones and sulfonamides was in good condition; as a banned drug, the risk probability of β2-receptor agonist did not reach 100% low risk, and supervision needed to be strengthened.

Conclusion

The constructed Bayesian network model has risk assessment and warning, and many kinds of drugs can be classified and supervised, which provides technical support for improving the accuracy and timeliness of veterinary drug residue risk management.
