Reese Witherspoon sparked a heated debate about whether it's safe to eat snow after sharing a video of herself making a Snow Salt Chococinno on TikTok. Scientists have long chewed over the age-old question: Is it safe to eat snow? A study published in 2016 found that snow in urban areas can absorb toxic substances from car exhaust. However, very fresh snow has very little bacteria, so it's best to dig in before it's 2 days old. Romanian researchers determined that very fresh snow has very little bacteria, so it should be dug into before 2 days have passed. Environmental scientist Staci Simonich told NPR in 2016 that she would not hesitate for her children to have the joy of eating a handful of fresh fallen snow from her backyard.
