Salmon may harbor infectious coronavirus for a week, say scientists

Live Mint  

Coronavirus lingering on chilled salmon may be infectious for more than a week, according to researchers in China, where imported fish have been investigated as a potential source of infections. Researchers at the South China Agricultural University and Guangdong Academy of Agricultural Sciences in Guangzhou found SARS-CoV-2, the virus that causes Covid-19, collected from salmon samples could survive for eight days at 4 degrees Celsius. Chinese authorities have been investigating imported meat, packaging and containers as a potential source of Covid-19 since June after repeatedly finding traces of the pathogen on packaging and food. “SARS-CoV-2-contaminated fish from one country can be easily transported to another country within one week, thus serving as one of the sources for international transmission,” the researchers said, noting the fish must be kept at a temperature of 0-4 degrees Celsius during shipping.
