Well, now an organization called Oceana has revealed, in a whopper of a publicity campaign that many of the fish for sale isn't what the label says. (hat tip: NY Times email digest; but since I no longer read their articles, since they want to restrict them to paying subscribers, I googled a phrase from the summary and found the same information on a different site)
According to Oceana’s new report, “Bait and Switch,” “[C]onsumers are frequently served the wrong fish — a completely different species than the one they paid for. Recent studies have found that seafood may be mislabeled as often as 25 to 70 percent of the time for fish like red snapper, wild salmon and Atlantic cod, disguising species that are less desirable, cheaper or more readily available (Miller and Mariani 2010, Buck 2007, Jacquet and Pauly 2008).”
“Estimates of red snapper fraud range as high as 77 percent (Marko et al. 2004),” the report adds, “or even 90 percent (Logan et al. 2008), as a proportion of DNA-tested fish.”
Jewish Laws of Kashrut require that we always know exactly what we're eating. The big question is:
At what stage of "production," the shipping, catching, skinning, fileting, packaging do the official kashrut observers enter the scene?
