Investigating the Heat Stability and Inactivation Conditions of Decapod Iridescent Virus 1 (DIV1)

open access: yesAnimal Research and One Health, EarlyView.
Heat treatment effectively inactivates decapod iridescent virus 1 (DIV1) under milder conditions than current WOAH recommendations. DIV1 infectivity was eliminated at 56°C for 30 min, 60°C for 15 min, or 70°C for 1 min, providing optimized heat treatment strategies for aquaculture biosecurity and seafood safety.
