The U.S. food system is under renewed strain as Covid-19’s Omicron variant stretches workforces from processing plants to grocery stores, leaving gaps on supermarket shelves.
In Arizona, one in 10 processing plant and distribution workers at a major produce company were recently out sick. In Massachusetts, employee illnesses have slowed the flow of fish to supermarkets and restaurants. A grocery chain in the U.S. Southeast had to hire temporary workers after roughly one-third of employees at its distribution centers fell ill.
Food-industry executives and analysts warn that the situation could persist for weeks or months, even as the current wave of Covid-19 infections eases. Recent virus-related absences among workers have added to continuing supply and transportation disruptions, keeping some foods scarce.
Nearly two years ago, Covid-19 lockdowns drove a surge in grocery buying that cleared store shelves of products such as meat, baking ingredients and paper goods.
Now some executives say supply challenges are worse than ever. The lack of workers leaves a broader range of products in short supply, food-industry executives said, with availability sometimes changing daily.
Supermarket operators and food makers say that overall supplies are ample, despite the continuing labor shortages and difficulties transporting goods. They say that shoppers will find what they are looking for, but may have to opt for different brands.
Eddie Quezada, produce manager at a Stop & Shop store in Northport, N.Y., said Omicron has stretched his department more than any previous wave of the pandemic, with one in five of his staff contracting Covid-19 in early January. Deliveries also have taken a hit, he said: Earlier in the month he received only 17 of the 48 cases of strawberries he had ordered.
“There is a domino effect in operations,” Mr. Quezada said.
At a Piggly Wiggly franchisee in Alabama and Georgia, about one-third of pickers needed to organize products and load trucks at the grocery chain’s distribution centers were out sick in the first week of January, said Keith Milligan, its controller. The company has been struggling to get food to stores on time due to driver shortages and staffing issues that haven’t improved, Mr. Milligan said, leaving Piggly Wiggly to change its ordering and stocking plans daily in some cases. Frozen vegetables and canned biscuits are running low, he said.
In-stock levels of food products at U.S. retailers hit 86% for the week ended Jan. 16, according to data from market-research firm IRI. That is lower than last summer and pre-pandemic levels of more than 90%. Sports drinks, frozen cookies and refrigerated dough are especially low, with in-stock levels in the 60% to 70% range. In-stock rates are lower in states such as Alaska and West Virginia, IRI data show.
“We were expecting supply issues to get resolved as we go into this period right now. Omicron has put a bit of a dent on that,” Vivek Sankaran, chief executive of Albertsons Cos., said on a Jan. 11 call with analysts. He said the Boise, Idaho-based supermarket giant expects more supply challenges over the next month or so.
