Deskripsi
Aquatic animals are an important source of food for humans, yet little is known about their potential to transfer zoonotic viruses. Multiple recent cases of SARS-CoV-2 from cold-chain aquatic food and environmental samples has evoked worldwide concerns, and even though these cases pale in comparison to poultry and livestock. To investigate the potential threat of food from aquatic animals, we map their transcriptomes to the genomes of human respiratory- and intestine-related viruses. Analyses only find an influenza virus sequence in a salmon (Salmo salar) skin transcriptome. BLAST and phylogenetic analyses identify this sequence as influenza A, and this likely owes to contamination from a worker. Thus, when prepared properly, aquatic animals can provide great nutritional benefits to humans while posing minimal health risks.
