Is eating from the first snow fall of the year unhealthy? As a child I was warned that the 1st snowfall was dirty snow. The theory was that as the flakes form they pick up more small airborne particles than rain might; since they are suspended longer and “trap” particles as they grow. Thus the first snow is laden with the particles (some also say the first snow has the largest flakes?). Subsequent snowfalls are formed in more “pure” air. Another theory is that the 1st snow has higher moisture content and is likely to pick up more particles as it falls to earth than drier snow.
I am not sure it matters as long as you aren’t gorging on snow. The biggest factor may be how much the snow gets contaminated while laying on the ground.SHARE
