Attention all shoppers: Just stop it. Please.

California grocers are urging coronavirus-obsessed customers to take a deep breath and put those seven extra tins of tuna fish and three-months supply of toilet paper back on the shelves. There’s plenty of groceries in the supply chain — and, if you give them a chance, your local grocer will eventually deliver it to you.

“The supply is there,” said Dave Heylen, spokesman for the California Grocers Association. The group represents roughly 80 percent of grocery retailers in the state, including Costco, Whole Foods, Raley’s, Albertson’s and Safeway. “It’s a fluid situation. Right now, we feel very confident we’ll be able to meet the needs if customers don’t over-buy.”

The spread of coronavirus has spun Bay Area shoppers into a frenzy. They are emptying aisles, stretching lines outside doors and hunting multiple shops for cleaning and paper products and other staples. Customer demand is also overwhelming online delivery services, and creating an immediate demand for drivers, stockers and check out clerks.

Seven Bay Area counties on Monday announced shelter-in-place restrictions for the next three weeks. Health officials deemed grocery stores and pharmacies essential services, and allowed them to keep regular hours.

The great unknown of the pandemic — how long people will self-quarantine, when will new county, state and federal guidelines further restrict movements — have pushed demand to historic levels.

Heylen said grocers and suppliers have been confident about getting goods to market. Major companies have contingency plans for continuing service during local emergencies like earthquakes, hurricanes and tornadoes, he said. The virus is different, however, because it’s striking nationwide.

The association has enlisted local elected leaders to tell consumers that by over-buying, they may be taking supplies more urgently needed by their neighbors.

But Heylen said overall, supply remains strong. Online customers may see some uncertainty in deliveries, he said, since volume is high and the services are relatively new.

Local grocers have also been taking cues from the Centers for Disease Control and Prevention, limiting contacts and deep cleaning throughout the stores. Some workers show up in gloves and masks.

School closings have put a further crimp on the workforce, as employees look after their children instead of running the meat departments and ringing up customers.

Online grocers have seen business surge 30 to 60 percent week-over-week, said Pradeep Elankumaran, co-founder and CEO of Farmstead. “The online grocery world is generally not ready for this kind of spike,” he said. “It’s pure operational hell.”

The San Francisco-based Farmstead has been managing orders for fresh produce among its 1,500 staples, but plans to double its workforce from 70 available warehouse workers and drivers.

Safeway also announced Monday it will be hiring more than 2,000 workers for its Safeway, Andronico’s, Vons, and Pak ‘N Save retail stores. The openings are available in Northern California, Hawaii and Nevada.

Elankumaran said the crisis will push Farmstead and other online grocery services to hone their business and expand their market. “It’s a challenging time for everyone,’ he said. Related Articles Coronavirus: Santa Clara County passes 20,000 cases amid statewide decline

Traditional brick and mortar stores have been limiting purchases of certain items for days — particularly sanitizers, cleaning products and toilet paper. Many have been cutting hours to allow for restocking and cleaning.

Product selection varies between Safeway stores, and workers are doing their best to re-stock and clean, according to the company. “As products run low, we are replenishing them just as soon as the supply chain allows,” said company spokeswoman Wendy Gutshall.

Fred Zanotto, vice president of operations at the family grocer Zanotto’s, said demand has been unlike anything he’s seen in his career. Even in the aftermath of the 1989 earthquake, shoppers were able to line up and purchase necessities.

Pac-12 football will be back in 2020, but the specifics remain a mystery In the past week, Zanotto’s has placed signs on shelves for certain products asking shoppers to limit their purchases. “The demand is high for everything,” he said.

But Zanotto said employees at the family’s four stores have been steadfast in showing up for work, and customers have been generally good-natured and understanding.

One shopper brought a basket of seven peanut butter jars. Zanotto asked if she really needed them all. The woman answered she was shopping for her neighbors.

“The only scary thing is just the unknown,” he said. “You just don’t know.”
