U.S. food banks dealing with increased demand from families sidelined by the pandemic now face a new challenge – surging food prices and supply chain issues. As holidays approach, some food banks worry they won't have enough turkeys, stuffing and cranberry sauce for Thanksgiving and Christmas.

OAKLAND, Calif. — U.S. food banks already dealing with increased demand from families sidelined by the pandemic now face a new challenge — surging food prices and supply chain issues walloping the nation.

The higher costs and limited availability mean some families may get smaller servings or substitutions for staples such as peanut butter, which some food banks are buying for nearly double what it cost two years ago. As holidays approach, some food banks worry they won’t have enough stuffing and cranberry sauce for Thanksgiving and Christmas.

“What happens when food prices go up is food insecurity for those who are experiencing it just gets worse,” said Katie Fitzgerald, chief operating officer of Feeding America, a nonprofit organization that coordinates the efforts of more than 200 food banks across the country.

Food banks that expanded to meet unprecedented demand brought on by the pandemic won’t be able to absorb forever food costs that are two to three times what they used to be, she said.

Supply chain disruptions, lower inventory and labor shortages have all contributed to increased costs for charities on which tens of millions of people in the U.S. rely on for nutrition. Donated food is more expensive to move because transportation costs are up, and bottlenecks at factories and ports make it difficult to get goods of all kinds.

If a food bank has to swap out for smaller sizes of canned tuna or make substitutions in order to stretch their dollars, Fitzgerald said, it’s like adding “insult to injury” to a family reeling from uncertainty.

Bryan Nichols, vice president of sales for Transnational Foods Inc., which delivers to more than 100 food banks associated with Feeding America, said canned foods from Asia — such as fruit cocktail, pears and mandarin oranges — have been stuck overseas because of a lack of shipping container space.

Issues in supply seem to be improving and prices stabilizing, but he expects costs to stay high after so many people got out of the shipping business during the pandemic. “An average container coming from Asia prior to COVID would cost about $4,000. Today, that same container is about $18,000,” he said.

Kate Waters, a spokeswoman for the USDA, which administers the SNAP program, said there were no immediate plans for an emergency boost in SNAP benefits to compensate for the rising food costs. But she said that previous moves by the Biden administration such as the permanent increase in SNAP benefits earlier this year and a fresh wave of funding for food banks should help ease the burden.
