One tea bag can contain DNA from up to 400 species of insects.

Scientists analyzed 40 samples of tea and dried herbs that people most often buy in supermarkets. The researchers note that they found exactly traces of “environmental” DNA there, which can be caught even from the air. In order for the DNA of an insect to remain on a tea leaf, he only needs to nibble it. The trace remains for a long time, until the moment the tea enters the cup. The author of a new study admitted that he prefers coffee precisely because coffee beans are roasted, during which any DNA breaks down.
