Do polar bears have worms?
Polar bears are especially susceptible to the parasitic roundworm Trichinella, which they contract by feeding on infected seals. Trichinella larvae encyst in various parts of the polar bear’s body, usually muscle tissue. If enough larvae encyst in one area, such as the heart, the tissue becomes severely damaged.
Do polar bears have trichinosis?
Trichinella parasites can infect a wide range of animals worldwide. In the lower 48 states, trichinellosis cases and outbreaks have been caused by the consumption of brown and black bear, wild boar, and cougar; in Alaska, walrus and black, brown, grizzly, and polar bear; and in Hawaii, wild boar.
What animals can carry trichinosis?
How is trichinosis spread? Animals such as pigs, dogs, cats, rats, and many wild animals (including fox, wolf, and polar bear) may carry the parasite. When humans eat infected pork or wild game that has not been properly cooked, they become infected.
Can polar bears get fleas?

These parasites are usually killed by cooking the fish to a temperature of at least 145°F for fifteen seconds. The Food Code and the Texas Food Establishment Rules require that fish that are to be consumed raw or undercooked be frozen at a temperature and time guaranteed to kill parasites.
Can you be cured of trichinosis?
Is there a cure? Most trichinosis infections have minor symptoms and do not require any treatment as all symptoms resolve without treatment. In those with more intense symptoms, thiabendazole (Mintezol) can be used to eliminate the adult worms in the gastrointestinal tract.
How does a Polar Bear Kill a seal?
Aquatic stalk is when a polar bear swims to a piece of sea ice and emerges from the water quickly to grab its prey. After capture, they disable the seal by biting it several times in the head and neck. They eat the skin and blubber first, then the meat, only to leave behind a few scraps.
How are polar bears different from other mobs?
Polar bears are neutral mobs, unless they are around their cubs. At that point, they are hostile.

Polar bears are also faster than a player when swimming.

How are polar bears protected in the wild?
Polar bears sit at the top of the food chain in the Arctic—they are the apex predators. Adult bears do not seem to have any potential predators in the wild.

Polar bears primarily feed on fat, which is relatively free of parasites; however, larvae of the Trichinella parasite have been confirmed in polar bears throughout their range, and antibodies to the protozoan parasite Toxoplasma gondii have been found in polar bears in Alaska (U.S.), Greenland and Svalbard (Norway).
What parasites do bears have?
