The Municipal Administration of the Macau Special Administrative Region Government has suspended the import application of a Danish cold storage and a Canadian processing fishing vessel after samples of the outer packaging of 'frozen Greenland halibut' imported from them tested positive for the new crown virus. However, subsequent tests on 12 samples of the outer packaging took from local merchants were negative, and no abnormalities were found. The government has formulated emergency plans and upgraded preventive and regulatory measures in response to the detection of the new crown virus in outer packaging of imported cold chain foods.
