Seriously, though, why throw out RAW! fish? It's almost always edible; put it in a cooler and send it to a food bank or similar. I hate to see GRR throw perfectly edible food in the trash when so many go hungry.
Edible/Not Edible. That's the litmus test that decides if food is thrown out. I've worked in restaurants and have seen much worse things happen to food before and have almost never seen anyone throw it out.
Don't believe the hype. They threw that food away because they were on TV. In the real world of restaurant food prep (where the customers can't see what goes on in the kitchen) they don't ever throw food away that easily. There is no chef Gordon department of quality control to kick dishes back to the kitchen when they don't pass muster. Once it's cooked it's served. They leave it to the customer to decide what is good or not good. Food costs money and a real world owner would probably fire any cook who threw food out like that.
