In order to assess possible risk of occurrence of pseudorabies（PR）in intensive swine farms in Sichuan Province，a questionnaire investigation was organized to identify the status of production and management in breeding farms，propagation farms and commercial farms in the province，risk paths of occurrence of PR were described by a scenario tree，and an assessment model was constructed within the risk evaluation framework proposed by OIE. Based on the results of investigation and background survey data，the risk value of each risk path was estimated by a matrix method through a qualitative risk assessment. The results showed that the high-risk paths of PR in the intensive farms in Sichuan Province included introduction of animals，use of semen，ineffective control of rodents，dogs and cats，geographical location and control of drinking water. The risk of PR transmission via personnel，vehicles，supplies，materials and other traditional pathways was greatly reduced due to improvement of bio-safety management level in recent years，and the conditions for PR purification in various intensive farms have been relatively mature. Risk assessment in combination with PR purification could help farms find out their own shortcomings related to risk and put forward targeted suggestions for prevention and control of the disease，which could provide strong technical support for PR purification.
