Lawsuit Over Subway Tuna Now Says Chicken, Pork, Cattle DNA Were Detected 136

Posted by msmash from the closer-look dept.
A new version of a lawsuit accusing Subway of deceiving the public about its tuna products said lab testing shows they contain animal proteins such as chicken, pork and cattle, and not the advertised "100% tuna." From a report: Karen Dhanowa and Nilima Amin filed a third version of their proposed class action this week in the federal court in San Francisco, near their homes in Alameda County. Subway said in a statement it will seek to dismiss the "reckless and improper" lawsuit. The chain said the plaintiffs have "filed three meritless complaints, changing their story each time," and that its "high-quality, wild-caught, 100% tuna" was regulated strictly in the United States and around the world. Since the case began in January, Subway has run TV ads and launched a website defending its tuna. It also revamped its menu but not its tuna, saying an upgrade wasn't needed. The original complaint claimed that Subway tuna salads, sandwiches and wraps were "bereft" of tuna, while an amended complaint said they were not 100% sustainably caught skipjack and yellowfin tuna.

    Even if it's possible there's something to the lawsuit, the first two lawsuits were clearly absurd. The first one claimed there's no tuna whatsoever in the tuna, which is not only something that's impossible to get away with, but they refused to release the lab tests.

    In the second lawsuit, they claimed it "was not 100 percent sustainably caught skipjack and yellowfin tuna" which is curiously specific wording. Are they really claiming that sustainable tuna have different DNA from unsustainable ones? And does that mean that they suddenly admit that the lab tests do show tuna when they claimed they didn't the first time? They didn't release the lab tests for this one either.

    At this point, I'd assume either 1) they're suing only for the publicity and don't believe anything's wrong, or 2) they're fanatics who don't understand that no evidence means no evidence. It's possible that they have evidence the third time, but I wouldn't bet on it.

    By the way editors, there's no link to read other than the previous article, so here: https://www.reuters.com/business/retail-consumer/new-lawsuit-over-subway-tuna-says-chicken-pork-cattle-dna-were-detected-2021-11-11/

    There's no way a "marine biologist" as stated in the Reuters write up could collect 20 samples of tuna from a Subway of all places and determine if their tuna was real tuna or not. First of all, tuna is red. The reason it looks brown in cans and the bags used to make tuna salad is that it's cooked twice, once in a convection oven before final packing, and again in a tort oven. That cooking process utterly destroys DNA, because it's very thoroughly cooked. On top of that, chicken and pork are very lightly cooked. Often they are salted heavily and cooked just to the point where any bacteria or pathogens would be eliminated. That's enough to damage DNA, but not destroy it. DNA also floats around like crazy; it's everywhere. Everything sheds it; that's why labs that do proper DNA medical testing for example require tight environmental control, because you can very easily contaminate a sample and create confusing results.

    Odds are that Subway would not allow these fools to test their supply chain's tuna, so it's most likely the samples came from buying a tuna sandwich from a Subway. Given that DNA floats just about everywhere, if the tuna happened to be sitting next to an open bin of say grilled chicken or sliced ham, like you would find at every lunch counter on the planet, you would get the results they found.

    But unfortunately for Subway, it makes for sensational headlines to turn this into a scandal to generate more clicks and sell more ad space in your newspaper, despite this being the most laughable attempt at a class action shakedown ever.

    Too bad we have so many lawyers in Congress, maybe if we had fewer we could see actual tort reform rather than this kind of thing which amounts to little more than a legal form of protection racketeering.
