Safe serving of snacks is important, especially since there are so many opportunities to serve them. It could be a small gathering in which everyone practices safety rules. Or it could be an event after the pandemic is over. It could be a small social group that gather on a regular basis, a club meeting, or even a holiday gathering once they are permitted.
The pandemic has changed many things, and handling of food is one of them. Perhaps some of the changes are best to maintain even after the pandemic abates. After all there have been quite a few outbreaks of disease over the years that have been accompanied by fear, a fear that would have been well founded had these prior diseases not been contained.
One thing that we should practice is to not handle food that will be consumed by others. This can be a daunting problem when children lick their fingers after finishing a cookie, then use the licked fingers to search for their favorite kind of cookie that they just know is in that big pile.
