4. Best Management Practices for Farm Biosecurity for Pig Production
This step helps define where the dirty versus clean boundaries are located and applies to most of routes of contamination. The video "Access to the CAZ and RAZ" (below) descibes the process. The boundary may include a physical barrier such as a fence or may just be a location where a set of rules apply for entry.
The Controlled Access Zone (CAZ) is the pig farm yard, including buildings and driveways, where access is limited and rules for entry apply to avoid cross-contamination, as between workers or rodents contacting contamination on the driveway from the dead stock or feed truck, for example. The Restricted Access Zone (RAZ) is where the pigs are housed and there would be a defined entry protocol. Identify and sketch these.
CAZ = Pig farm yard including buildings and driveways.
RAZ = inside of buildings where the pigs are housed.
4.2.1 Driveway surfaces should be constructed of hard surfaces or gravel to avoid the pooling of water and to make cleaning easier.
22.214.171.124 Install at the points of access a gate or barrier that can be locked.
126.96.36.199 Signs should direct traffic flow as well as assist visitors.
188.8.131.52 Entry of CAZ is only allowed when preauthorized by management.
184.108.40.206 Visitor parking should be outside the CAZ.
220.127.116.11 A log for vehicles and drivers entering the CAZ should be maintained. Regularly reoccurring entries, feed trucks for example, may use delivery slips as a record.
18.104.22.168 The boundary must be in an entrance room (anteroom).
22.214.171.124 The boundary can be a bench or shower where the entrance procedure is completed.
126.96.36.199 Entry into the RAZ should be kept locked.
Doors to the barns must be kept locked to prevent accidental uninvited visitors from entering.
