You may have already tried this as a child, but it appears fresh snow might be safe to eat. The team found that snow that is a half-day old is safe to eat, especially in the colder months. Scientists collected snow from a park and from a roundabout in central Romania in January and February 2017, when temperatures ranged from minus 1.1C to minus 17.4C. A day later scientists found there were five bacteria per millimetre of snow in January. According to Istvan Mathe, a professor at the Sapientia Hungarian University of Transylvania, snow that is two days old is not safe to eat.
