China imports about 80,000 tonnes of frozen salmon every year. Chile, Norway, Faroe Islands, Australia, and Canada are the main exporters to China.
Lin Li, chief scientist of a team that monitors aquatic disease and control in Guangdong Province, told the Global Times it is not possible for live salmon to be contaminated with the virus as it breeds in the ocean, neither can frozen salmon be a source of Covid-19 which can only exist in active cells.
Forty-six people in Beijing have tested positive for the coronavirus over the last few days, the Global Times report said.
