Application of HACCP in vector control of passenger trains
Objective To explore the application of HACCP system in vector control of passenger trains.Methods According to the seven steps of HACCP,the vector control of train was implemented,including hazard analysis,determination of critical control points,determination of critical control point threshold,critical control point threshold evaluation,corrective measures,verification procedures,establishment of documents and records.Results Eight risk factors were identified,including whether the vehicle was air-conditioned and sealed,whether the"four entry"train was used,and vehicle type,vehicle age,vehicle driving direction,vector status of passenger car servicing station,vehicle detection history,and the season when the vehicle was investigated.After controlling the risk factors,the overall level of positive rate decreased from 4.8％to 1.9％,with statistically significant difference(x2=9.311,P=0.002).Conclusion HACCP system can improve the effect of vector control on passenger trains,help to improve the competitiveness and credibility of enterprises in the market,and promote the development of enterprises.
