I almost never eat raw fish anymore, the occasional piece of tuna maybe, but generally everything should be cooked. Raw meat is just stupid.
So how do you keep a clean bill of health in the age of tapeworms? Since tapeworms live in the fish muscle and are destroyed by heat, it’s best to eat only fully cooked salmon. If you have to order sushi or ceviche, stick with critters like tuna that don’t spend time in rivers.
