When entering Taiwan (China), passengers who carry meat or other meat-based food are subject to fines of between NT$10,000 and NT$1 million (US$300-32,000).
In Japan, passengers are required to comply with local regulations on fresh meat, processed food, and fruit and vegetables. In the case not having certificates, they face up to three years in prison or fines of up to JPY1 million (US$8900).
Meanwhile, passengers arriving in Australia will have to fill in the incoming passenger card to declare goods with risks, including food, plant materials, animal-based products and cooking ingredients.
Even a small amount of light snacks also requires declaration.
Those failing to declare such goods or declaring incorrectly may face imprisonment and a fine of up to AUD420,000.
Passengers are recommended to obey these regulations in order to avoid massive fines and prevent diseases.
Leaflets have been distributed by Vietnam Airlines to passengers at check-in areas, while audio and video announcements are also broadcast on flights bound for the aforementioned destinations.
