I just found this resource from the CDC about what they are suggesting as levels of safeness (is that a word?) for Halloween and the upcoming other holidays.
I think this is a great resource for food bloggers to look at and come up with creative ideas for your readers.
Looks like “traditional” trick or treating is not suggested, but giving out goodie bags that are easily picked up individually, like if you set them out on a table, etc, is a suggestion.
Anyway, here’s the link: CDC Holiday Celebrations
