There's some fascinating research going on in Brazil that could save burn victims from unnecessary pain and infections.

In Brazil, fish farming is a big business, but farmers typically throw away the skin from farmed tilapia. Doctors are experimenting with these skins — after they've been sterilized, of course — as bandages for burn victims, reports Stat. (Yes, there are some horror movie scenarios that come to mind, but listen to the science before your mind goes too far.)

The patient is covered in fish skin because researchers have found that collagen proteins, which help skin scar, are abundant in tilapia skin, even more so than in human skin. In a country where human skin, pig skin and other artificial bandage alternatives are in short supply, this tilapia skin research could make a tremendous difference.

When there's no alternative, Brazilian doctors cover burns with traditional bandages, which have to be changed daily to help prevent infection. Changing the bandages is painful, and the bandages don't help the wound heal. The tilapia skin not only can stay on for days or weeks at time, but it also blocks contamination, accelerates the healing process, and reduces the need for pain medication.

Tilapia skin used on animals

Tilapia skin is also beneficial for animals that suffer from burn wounds.

During the California wildfires in December 2017, a mountain lion cub and two adult bears suffered burns on their paws and were having difficulty walking. The animals were taken to the California Department of Fish and Wildfire for treatment in conjunction with veterinarians at the University of California, Davis. Vets decided to use tilapia skin to heal the wounds after reading about Brazilian doctors trying it.

“It’s like having little shoes on — fish shoes,” said Jamie Peyton, chief of the Integrative Medicine Service at the university’s vet school. Another benefit of using the organic material on a wild animal is that it's safe if ingested as opposed to traditional bandages.

The vets stitched the fish skin to the animals' paws when they were already under anesthesia for bandage changes or other care, then wrapped the treated feet with outer bandages made of corn husks.

In a matter of weeks, new skin had grown back on the bears’ paw pads and they were released back into the wild in late January. The mountain lion is still recovering and keeps nibbling at his edible fishy bandages.

Peyton says her team hopes to research the fish-skin treatment further and someday use it as a treatment for companion animals.

How effective is it on humans?

Right now the use of sterilized fish skin is limited to clinical trials, but those trials have been promising. Fifty-two patients have been treated using the method, and there have been no complications, barring the movie scenario reminders.

If you're concerned about awaking and finding fish skin covering your body in the hospital, there's not much of a chance of that happening here in the U.S. Donated human skin and animal-based skin substitutes are plentiful. But in Brazil and other developing countries, tilapia skin is a cost-effective solution that has environmentally sustainable side benefits.
