I think one of the most interesting techniques for burn victims is using placentas. I haven't seen it too much in my current hospital system, but have seen it talked about at medical association conferences and think it's pretty exciting.

Here is a gift link for an article about them in the New York Times from about a year ago.

TLDR; Its a fantastic substitute for bandages in the sense that you don't need to take off the fish skin everyday. Its also better are retaining moisture in the burn wounds than cotton badages. No need for antibiotics, painkillers etc Its also really cheap. Fish farms regard them as waste.

I think any farmed animal is or should have no waste. Even if it’s turned into cat food the skin is most definitely not just waste, there’s uses out there. However, if it is as cheap and readily available as cat food then that’s great for burn victims too.

How expensive is the sterilization process, though? That would be my primary concern if tilapia-skin bandages started to get widely available/mass-produced: that unscrupulous vendors would cut corners during sterilization, and then the burn victims would get nasty infections from remnant bacteria on the tilapia skin.

There is an Icelandic company called Kerecis that produces these kinds of fish skin based grafts. There are some videos of some of their patient's before and after over at their webpage[0] but be warned, they might be a bit graphic for some. [0]: https://kerecis.com

Wow, those before and after videos really are amazing - while my own scars are tiny, they aremore noticeable than some of these fairly major wounds.

> In the US, animal-based skin substitutes require levels of scrutiny from the Food and Drug Administration and animal rights groups that can drive up costs, Lee said. Given the substantial supply of donated human skin, tilapia skin is unlikely to arrive at American hospitals anytime soon. This reminds me of Milton Friedman’s arguments against the FDA.

I wonder what’s the difference between countries that drives that. It’s not like Brazil doesn’t have its own FDA, which is much more strict than the US one, from what I know. Maybe some kind of lobbying? Or are animal rights group that much stronger?

Unless we are talking about pesticides, where Brazil is effectively dumping grounds for substances banned in EU. Every time some pesticide is forbidden in Europe, brazilian regulators are happy allowing local agribusiness import it by the ton in fire sales: https://www.brasildefato.com.br/2025/10/14/export-grade-pois...

Dunno what method they use, but gamma irradiation is pretty cheap at scale

This has been going for long enough that there's been several metastudies debunking it. Was hyped in the news around 2017. Fish skin or silver sulfadiazine had similar effects and to me are both approximating placebo from the studies I read. The fish does nothing for pain and no difference in the scarring time vs the silver ointments.

fish skin (rich in collagen) sounds like a version of collagen patch. And for collagen patch for example https://pmc.ncbi.nlm.nih.gov/articles/PMC3081477/ where despite the "Conclusion" the "Results" show that it helps (and one can also expect that collagen patching is starting point to engineering artificial skin) : Results: With two weeks of treatment, 60% of the ‘collagen group’ wounds and only 42% of the ‘convent…

You made me go re-search for those meta studies and I can only find a brazilian one which disputes the claims but I do find a few showing benefits. I'm back to not knowing what to believe in isolation, but with results also for plasters that you shared I'm more leaning towards you being right. Thanks for sharing.

Earlier quoted context omitted.

What's special is that tilapia is probably cheaper than even the local fish since it's farmed in massive quantities and shipped all over the world as food. If other fish skins were tried it must have been similar results.

Tilapia imports are heavily restricted to Australia, The live fish will not be allowed, they are considered "restricted noxious fish". The rules are: Illegal to Keep: You cannot keep tilapia (dead or alive), sell them, give them away, or use them as bait. Immediate Euthanasia: Humanely kill the fish as soon as you catch it. Disposal: Bury: Bury them deep and well away from the water's edge to prevent scavengers from…

I also hear you can dispose of them by placing them in a pan with fresh pulverized tomato, garlic, olive oil, basil, then a little lemon juice, oregano then finally, salt and pepper to taste. Highly effective, efficient and delicious.

My nephew had multiple heart surgery, and after the last one, he kept having the wound release liquids. For months, they just medicated the wound regularly hoping it would solve by itself. At last, they decided for a cleaning surgery, and a pediatric specialist came from Rome and apparently brought something like "fish sheets" to "cover the wound while it heals.
