Arizonans can help "stamp out hunger" at the largest single-day food drive in the world this weekend.
On Saturday, letter carriers nationwide, including 5,000 in the Valley, will pick up canned food items on their regular mail routes.
The drive started over 40 years ago in Arizona and has grown nationwide.
Currently, food donations in the Valley are down, according to St. Mary's Spokesperson Jerry Brown.
Brown says typically donations drop heading into summer -- one of their busiest times for helping others.
"There's four million people in the Valley," said Brown. "If everyone donated one can -- that would be four million cans for food banks. That's enough to get us through summer."
To participate, just leave canned goods at your mailbox on Saturday.
Brown says the most needed items are canned fruit and vegetables, soups and meals in a can, pasta, peanut butter, tuna, rice and cereal.
