How is Wagyu beef killed in the USA?

Could you elaborate on the process used to slaughter Wagyu beef cattle in the United States? I'm curious about the methods employed to ensure the humane and ethical treatment of these animals, as well as any regulations or industry standards that may be in place to guide this process. Is there a particular method that is typically favored, or does it vary depending on the farm or facility? Additionally, how does this process compare to other countries where Wagyu beef is produced?
