Just a quick update to my post from this morning about how most tuna sold in the U.S. is not actually tuna, and that 84% of fish samples labeled “white tuna” were actually escolar, a fish that can cause prolonged, uncontrollable, oily anal leakage.
In that post I joked that, rather than giving up on tuna altogether, one could choose to carry around a DNA analyzer, knowing full well that no such consumer device actually exists, much less one that’s portable enough.
And yet, a mere hour later, I read that a device, aimed at grouper fish fraud, which is apparently a thing, will soon be available for the low, low introductory price of $2,000, and that devices for identifying other fish are on the way.
Via the Los Angeles Times:
Scientists develop sensor to sniff out fish fraud
…scientists at the University of South Florida College of Marine Science have come up with a handy little portable gadget that can identify exactly what kind of fish you’re eating — even if it’s cooked and smothered in sauce.
