A separate biosecurity protocol would be devised for hatcheries . the hatcheries would for example have to be bird - proofed and the hatchery workers should not have contact with other live poultry 渔护署将会制订另一套关于孵化鸡蛋的生物安全守则，例如孵蛋场必须有防雀措施，孵化场的员工亦不应接触其他活生家禽。

Ash trees can resist many dieases , but they can not resist the emerald ash borer . it lays eggs on the bark , then the young larva drill into and feed on the inner bark . this harms the ability of the tree to transport water and nutrients . the insect is attacking tree farms and can also spread when logs and firewood are transported 灰树可以抵御很多疾病,但是它们不能抵御灰虫.灰虫在树皮上孵蛋,那么幼虫钻入树皮并以内部树皮为食.这个破坏了树木传输水和营养的能力.昆虫正在攻击树木的耕种,并且当圆木和柴火运输的时候它们就能传播
