Can you eat 12 hour old sushi?

Can you really consume sushi that's been sitting around for 12 hours? I'm curious about the safety concerns here. Sushi, being a raw fish dish, is known to be highly perishable. With the passage of time, bacteria can multiply rapidly, posing a risk of food poisoning. So, is it advisable to indulge in 12-hour-old sushi? What are the potential health hazards one might face? And are there any specific guidelines or best practices to follow when it comes to consuming sushi, especially when it comes to its freshness and storage?
