The new test is called ELISA, for enzyme-linked immunosorbant assay, and it makes use of the fact that the blood of animals with trichinosis infections contains specific proteins secreted by the worms. The ELISA test can detect those worm proteins in a blood sample taken at slaughter.
How do you know if bear meat has trichinosis?
Trichinosis is hard to detect when butchering because there are few signs. Larvae form cysts usually in the muscles of the jaw, tongue, and diaphragm. Cysts may not be visible to the naked eye. Animals may have swollen intestines with small bruises.
Where do you test for bear meat for trichinosis?
Dr. Berit Bangoura from the University of Wyoming Veterinary Service identifies the two best places to be the diaphragm of the animal as well as the tongue. Samples from these tissues often have the greatest density of trichinosis larvae. The best samples are cooled, not frozen, and are from within a few days.
Does canning bear meat kill trichinosis?
Know that other processing methods don’t kill parasites.
Other methods of meat processing or preserving, such as smoking, curing and pickling, don’t kill trichinella parasites in infected meat.
Can you get rid of trichinosis?
Anti-parasitic medication is the first line of treatment for trichinosis. If the trichinella parasite is discovered early, albendazole (Albenza) or mebendazole (Emverm) can be effective in eliminating the worms and larvae in the intestine. You may have mild gastrointestinal side effects during the course of treatment.
How long does trichinosis last?
These symptoms can last from 5 to 45 days, but they usually begin to appear 10 to 14 days after consuming the infected meat. Milder cases of trichinosis are often mistaken for the flu or other common illnesses. In extreme cases, trichinosis may result in death.
How do you know if you have trichinosis?
Nausea, diarrhea, vomiting, fatigue, fever, and abdominal discomfort are often the first symptoms of trichinellosis. Headaches, fevers, chills, cough, swelling of the face and eyes, aching joints and muscle pains, itchy skin, diarrhea, or constipation may follow the first symptoms.
What temp kills trichinosis?
The actual temperature that kills the trichinella parasite is 137°F, which happens to be medium-rare. But be forewarned: Every iota of meat must hit that temperature to kill the parasite, and cooking bear meat to medium-rare isn’t a guarantee of that.
Why does all bear meat have trichinosis?
Trichinosis is mainly spread when undercooked meat containing Trichinella cysts is eaten. In North America this is most often bear, but infection can also occur from pork, boar, and dog meat. Several species of Trichinella can cause disease, with T. spiralis being the most common.
