Letter carriers across zip code 55616 will be doing more than delivering mail on Saturday, May 11 - they'll also be collecting bags of food for the 27th annual Stamp Out Hunger Food Drive.

The food drive is the largest one-day food drive collection event in the nation, carried out over 10,000 American cities across America. The Two Harbors Food Shelf collected over 4,200 pounds of donations last year.

To participate, the National Association of Letter Carriers asks residents to fill one or more bags with nonperishable, non-expired food and place the bags by their mailboxes by 9 a.m. Saturday. Donations can also be left in the collection box at the Knife River Post Office and the collection box at Super One Foods in Two Harbors.

Wishlist items include canned fruits and vegetables, all canned beans, canned meats and condiments such as salsa, pickles and relish. Soups, pasta and pasta sauce, peanut butter and brown rice, as well as diapers and health and hygiene products, are among the biggest needs. However, any nonperishable item in its original packaging that isn't expired will be accepted.

Volunteers are needed to bring in and sort donations. Sign up for one of two shifts, 9 a.m. to 12:30 p.m. or 12:30-4 p.m., by visiting the food shelf's Facebook page and clicking on "Stamp Out Hunger Volunteer Event."
