I'm a bit torn on this issue. I'm somewhat agreed that if you pay for something that you don't know what it is, you deserve what you get. On the other hand, more to your point, there's also a safety issue about this as well. I found this article-The New Bait and Switch on Seafood that describes the seafood fraud more in depth. She describes the types of fraud in levels from most benign to most dangerous. When it gets to the level that people can die from the fraud, it's pretty severe. In this case, toxic puffer fish was substituted for monkfish and caused two people to nearly die.After two Chicago diners nearly died from bad fish in 2007, FDA investigators used forensic DNA barcoding to discover that the supposed monkfish on menus was actually the highly toxic puffer fish, resulting in the recall of nearly 300 cases of seafood.
