I don’t know what bitlong is, but it’s apparently popular in South Africa and apparently it’s made from whatever meat is available.

Using DNA analysis on biltong, researchers found, according to the N.Y Times,  horse meat labeled as springbok, the native gazelle; giraffe meat labeled as the African antelope, kudu; and in an inexplicable case, kangaroo labeled as ostrich.

“For me the saddest finding was to find the Cape mountain zebra, an endangered species, being sold as biltong,” said Maria Eugenia D’Amato, a geneticist at the University of the Western Cape in South Africa and one of the authors of the study, in the journal Investigative Genetics.

From a total of 146 samples of biltong, sausage and minced meat, more than a hundred pieces of meat were mislabeled.

Beef was correctly labeled in all of the samples.

“Our biggest surprise was to find kangaroo in the samples,” Dr. D’Amato said. “This isn’t found anywhere on the continent, and it must have been imported.”
