LEE COUNTY, Fla.- "Stamp Out Hunger" is the one day when letter carriers collect non-perishable food that has been left by mailboxes. You can leave yours out today.

The "Stamp Out Hunger" event is the nation's largest single-day food drive. Letter carriers throughout Southwest Florida will be collecting nonperishable food during their 21st annual drive. 

Food collected in Lee County will be distributed by the Harry Chapin Food Bank and several other agencies; food collected in Collier County will be distributed by Collier Harvest.  All food collected in food drives is distributed to participating agencies at no cost.

Virtually any kind of food may be donated in unopened, nonbreakable containers.  Items especially in need are peanut butter, tuna, rice, beans, and canned meats, fruits, vegetables, and soups. You can leave your items in a bag or box at your mailbox.
