called the lawsuit meritless and maintains it buys only skipjack and yellowfin tuna from fisheries with stocks that aren't overfished.with results of a commercial lab analysis of"60 inches worth of Subway tuna sandwiches" purchased from three different locations in Los Angeles. The tuna meat was removed, froze, and shipped for testing.
A spokesperson for the lab told the Times that the results pointed to two possible scenarios."One, it's so heavily processed that whatever we could pull out, we couldn't make an identification. Or we got some and there's just nothing there that's tuna," the spokesperson said. The newspaper also notes that it's not the first to try and uncover whether Subway's popular tuna sandwich do indeed contain all tuna.and found the tuna purchased in the sandwiches was in fact tuna.
2 questions: 1. can they find tuna DNA in canned tuna that is frozen & sent in for identification? 2. why not compare composition of amino acids or proteins of Subway's supposed tuna & mayo with known similarly cooked/processed tuna & mayo instead of DNA? More reliable
good luck
