Australia and New Zealand are the two countries recognized as the ones with the most stringent inspection and quarantine measures in the world. The mail inspection work in China, Australia and New Zealand was compared on the aspects of mail quarantine system, inspection, quarantine treatment and punishment, based on which something worth learning and referring could be found and some suggestions were put forward, with the aim to provide theoretical basis for the animal and plant quarantine of entry mails.展开更多
