Labs Are Euthanizing Thousands of Mice In Response To Coronavirus Pandemic (sciencemag.org) 65

sciencehabit writes: Science Magazine has learned that researchers across the U.S. are euthanizing thousands of lab mice in anticipation of a shortage of workers who can care for them. Some scientists have had to sacrifice half or more of their colonies, potentially resulting in the loss of months or years of work. "I was staring at my mice one by one and deciding who lives and who dies," says one researcher. "It was really rough." At the moment, Science has not seen evidence that larger animals such as cats, dogs, or monkeys are being proactively euthanized. That will likely remain the case. Unlike larger animals, mice breed quickly and must be used quickly. And because they comprise about 95% of all research animals, they suck up the most money and time.

  • If I was a mouse, I'd certainly prefer to be euthanized painlessly and quickly instead of remaining a lab rat subject to experiments.

      It would certainly take some unusual science to turn a lab mouse into a lab rat!
      • Well, the mouse can identify as a rat.

          They call these people scientists? They're referring to test animals as persons. No wonder the Wuhan virus made it out of containment.

          • You've got to be pretty blind or willfully ignorant to think there's something special about humans that grants us personhood.

            We're all animals. Humans are a lot brighter than most, but most everything that makes us something other than calculators is shared with most other higher animals.

            You can value another being's life far less than a human one, without denying their personhood. They love, they hate, they fear... all evidence indicates they're just as sentient as us, just far less sapient.

      Not every lab mouse is getting injected with some untested concoction and then dissected to see what effects it had on them. If scientists are doing a proper job of things, a good amount of these mice are going to be control group subjects in which case the biggest crime is that they get to live out a pretty boring existence. Even of the mice used in experimental groups, a lot of them merely have their diets changed to observe effects over the lifetime of the animal.

      If you think that every lab animal endures a life of excruciating torture and pain, then I'm not really sure what to tell you. Perhaps we should just release them all into the wild where they'll live happy Disney movie lives free from harm [wikipedia.org] or worry [wikipedia.org].

      I have a PhD in biochemistry. I've worked in mouse labs, I've worked in yeast labs, I've worked in E coli labs, I've worked in human cell culture labs, and now I work in a plant lab. The fact you suggest that we "make them suffer fog [sic] a long time" shows you don't know what is actually going on.

      To even be approved to do mouse work at any US university (and most other countries as well) you have to clear many hurdles first:
      • You have to show that you can't do the work with a simpler system (including cell culture)
      • You have to have a plan in place for caring for the animals, including feeding them, handling waste, and handling their remains
      • You have to have either trained people on your staff or at your facility who can monitor their well-being
      • You have to have your methods reviewed by a DVM and an ethics board
      • You have to use the most humane euthanasia technique possible for your methods

      You can't just let the animals suffer, even if they are mice; you'll never get approval or funding to do so. Even though mice get the least attention from regulatory inspectors they still count at the institutional level. When I was in the mouse lab we had a special facility in the (rather small) school that was dedicated to mice; grad students were absolutely not allowed in without a post-doc, faculty member, or DVM accompanying them. Each animal was accounted for, birth to death. Each cage had to be paid for by the PI all the way through and no animals were allowed to be acquired or birthed unless the supplies were already ready for them.

      • I'm guessing there are way, way more cumulative mouse-hours of suffering at the hands of people using glue traps to catch them than there are scientists using them for laboratory experiments.
    • We all die in the end. The only question is how long, and how well, we live in the meantime.
      That's kind of the whole point of free range farming - just because you intend to eventually eat an animal doesn't necessarily mean you're okay with commissioning it to live a short, miserable existence until then.

      • Mice have a higher lifespan in an enclosure than they do in the wild. Regular meals, regulated temperature, fewer diseases, no ticks, no predators, no poison. And a white mouse tends to do very poorly in the wild as it lacks even the most basic camouflage. I've kept extra mice from the lab as pets, my longest lives one last just short of 4 years the next oldest was 2.5 years.

        • I was trying to argue that just because we plan to kill them anyway, that doesn't mean killing them today for no good reason is morally equivalent.

          Sure, an engineered breed of severely inbred mice that should never have existed in the first place, do poorly in the wild. That doesn't reduce the moral price paid for breeding new ones that will be subjected to a lifetime of imprisonment and experimentation. The benefits we get may be worth it, I just think it's extremely disingenuous to pretend a price isn't

          • Sure, an engineered breed of severely inbred mice that should never have existed in the first place, do poorly in the wild.

            lab mouse, fancy mouse, and the wild house mouse are all related and all in the same ballpark for life span captivity.

            If you try to argue that it's completely fine to subject mice to imprisonment and experimentation with no moral qualms since it helps humans,

            Morality or immorality is a non sequitur position, and nobody could rationally debate it. Sorry!

            Is it ethical to breed and use live animals for experimentation? The general consensus is that yes it is, under limited circumstance. There are some great essays discussing the ethics of either position that I think are worth reading. (and was, and may still be, required reading in ethics classes

For particular strains, depending on what was done to them, you would have to add up all the hours technicians spent getting them that far.

    Such a poor criteria for deciding who gets to remain open, rather than "risk of disease transmission". And one that's subject to arbitrary political whims. In the bay area, marijuana dispensaries are declared "essential". Gotta keep people lining up to get their pot, after all. In Ontario, new car dealerships are declared "essential" - not just their repair shops, but the whole dealerships.

    Totally different here; here, places are shut down based on disease risk. Which is a huge incentive for businesses to take steps to reduce their risk of disease transfer. The other day, for example, I ordered a vinyl wrap from a small printing company. Surely anyone would declare such a company to be nonessential. Yet it's run by a guy working by himself. He took my order online. I showed up for him to measure the hood - I didn't need to be anywhere near him. He'll only be touching the hood when he wraps it, and never getting inside the vehicle. Why exactly should this be banned, unless hurting the economy is the goal? For me, delaying this purchase would be a minor inconvenience, but for him, it's his livelihood. What buys him food and pays his rent.

    These sorts of things are not a significant means of disease transmission outside of the household. That's things like parties, public transit, crowded restaurants / bar / shops / etc, dense lines, and so forth, which put people in close contact with numerous random people for long periods. Where businesses are fundamentally incompatible with social distancing - to pick an example, hair salons - yes, this can mean forcing shutdowns. For others - restaurants, theatres, stores, etc - business as usual is too dangerous, but with significantly reduced capacity and employee hygiene measures, spread can be reduced to minimal levels. Public transit may need to (in addition to additional cleaning costs) reduce capacity and/or shift traffic to lower-demand times, which may require prioritizing certain riders and may potentially indirectly disrupt businesses as a result - but indirect disruption is a different topic than specifically-ordered shutdowns. And while governments may be hesitant to enforce against private gatherings, as major sources of the spread of disease, enforcing against them is very important, because they're major sources of spread between groups.

    The goal should be to disrupt life as little as possible while disrupting transmission to the maximal extent. These "some arbitrary politician declares certain companies essential or nonessential while doing little concerning things that are actually serious sources of spread" policies are... not that. Yes, it is a way to reduce spread, but a very economically inefficient one relative to how much spread you reduce.
