This Saturday is the United States Postal Service’s 20th Annual “Stamp Out Hunger” Food Drive. Postal customers are asked to leave non-perishable food items at, or next to, their mailboxes. Donations of food go to pantries in the communities where they’re collected. Examples of non-perishable items include canned soups, canned meats and fish, canned vegetables, fruits and juices, boxed goods, pasta and rice. Glass containers are not accepted because they can pose a risk to carriers and pantry volunteers if they’re broken in transit. The Post Office has collected more than one billion pounds of food since it began in 1993.
