“There is no evidence that sanitizing your groceries after shopping will help protect you. “
As Nassim Taleb says “Absence of evidence does not mean evidence of absence”.
Or in other words. Just because we don’t see evidence doesn’t mean there isn’t any!
Wether you decide to wipe down your groceries or not is up to you. But in my opinion it’s a very low cost for a potentially very high payoff.
