约翰•盖德：如何打造你心目中坚不可摧的猪场?

Next, the farm is divided into 2 areas, one where visitors' footwear, clothes, utensils and vehicles never cross into the areas used by the farm staff and likewise the farm staff (and of course their pigs) never travel over surfaces available to ‘outside’ individuals and their vehicles. Notice that the surfaces used by the farm staff and their vehicles (A, B and C on the plan) are fenced off securely from those surfaces used by visiting people and their vehicles, such as those delivering supplies, including bulk feeds and equipment, and others removing finished pigs for sale and any dead stock to be disposed.

其次，猪场分成两个区域，一个供来访者使用，他们的鞋子、衣服、工具和车辆不会进入到猪场员工的区域；同样的，猪场员工和猪群也不会接触到对外来者开放的区域。注意，猪场员工及其车辆可用的区域（图示A、B、C区）已经筑起一道安全围栏，与来访者及其车辆（比如必需品的运送，包括饲料、设备等）隔离开，并和待出售的育肥猪、待处理的死畜所经之路隔开。

Keeping your farm staff ‘in’ their working areas is as important as keeping all others ‘out’ of them.

让猪场员工待在他们自己的工作区域，和让其它外部事物远离他们一样重要。

Visiting veterinarian

兽医来访

Only the visiting veterinarian is allowed in (via the staff showers) but it is essential that he leaves his vehicle either off the farm or in the visitor’s car park, and his equipment enters via the delivery’s drop-off point. The same goes for other outside professionals – electricians, plumbers, ventilationists and those needed to fix equipment and computers must only enter by the staff entry facilities.

只允许兽医（经过员工沐浴通道）进入猪场，但他必须把车停在远离猪场的地方或者来访者指定停车处，他的工具经由指定入口送入。其他外部专业人员也是如此，电工、水管工、通风设备维修工、其它设备维修工及电脑维修人员，只能从员工入口进入猪场。

理论上，鸟类和啮齿动物也可以进入一个保护良好的猪场，这也应当引起注意。

Of course rodents and birds can transgress these barriers – the answer is to appoint both a rodent controller member of the staff, and have another one responsible for bird control.

当然，啮齿动物和鸟类可以越过这些屏障，解决办法是任命一名专职人员对啮齿动物进行控制，同时另外聘请一名负责控制鸟类的工作人员。
