Nah, lots of inexpensive sushi is quite safe. The trick is that the sashimi is irradiated, killing all the potential biologicals. It’s no where near the quality you’ll get at a 4 star Japanese place, but I have developed a taste for it. I usually buy the seaside combo at the grocery store and pop it in my mouth on the drive home.
I am gonna disagree on that Melas. Too much chopping of veggies and fish-type-pre-cooked-stuff. Not something a typical school cafeteria can do safely. Worker safety and bio-safety.
You want a public school cafeteria worker using a mandolin? And certainly not one wielding a cleaver in skinnier than julienne slicing of veggies.
Not even considering the raw fish — that’s wholly out of the question.
But I’m no master of school cafeteria costs and management. Still, it is something that seems scary to me.
