Scientists in mainly Muslim Kazakhstan have come up with an instant test for the presence of pork in food, a popular newspaper reported on Monday.
The plastic-stick test detects food molecules that are found only in pork, which is forbidden by Islam but is easily found in the Central Asian state, Megapolis weekly said.
"It's no secret that some chefs cheat and add pork to beef to make the dish cheaper," the newspaper wrote on Monday, saying the practice was widespread in Kazakhstan.
"When you get your beef patty, cut off a couple of small pieces and drop them in a glass of water. Stir, shake, put the test stick in ... In a minute or two you will see the result."
Megapolis said it was unclear when the test, in which the stick changes colour as in a pregnancy test, would become widely available.
