Why are American eggs not safe to eat raw?

I've heard that it's not SAFE to eat raw eggs in the United States, but I'm not quite sure why. Could you explain the reasons behind this? Are there specific regulations or standards that American eggs don't meet that make them unsafe for raw consumption? I'm particularly interested in understanding the potential health risks associated with consuming raw American eggs, and what steps can be taken to minimize these risks. Additionally, are there any alternatives to raw eggs that offer similar nutritional benefits but are considered safer to consume?
