I had sushi for lunch today and it was FANTASTIC
I love ceviche. But I buy the fish from a place I trust and make it myself. And I enjoy sushi, too, again in a trustworthy restaurant, and where I live there are some excellent sushi places. But think about quality control and guaranteeing the health of 700,000 students on sushi day in a public school system that big, which contracts for its food suppliers to a large extent based on price. I would not let my children eat raw fish at a public school.
