A few years ago during the flu outbreak, many may not have understood how to disinfect周转箱周转boxes. It was only online that I learned about a specific process.
This was originally an ultraviolet light, where the staff at the chicken farm temporarily disinfected their white coats. Not far to the right of the main gate is a workspace for handling plastic crates. The crates brought back usually need to soak in caustic soda for a while before being washed with clean water.
Here, it's clear to everyone that the周转箱 needs to be disinfected.
