Grocery workers around the world are among those on the frontline of the Covid-19 crisis and they have earned praise from the likes of Pope Francis and former US president Barack Obama for their role in keeping people supplied.
Toilet paper, eggs, produce and canned goods fly off the shelves with households locked down across the world and the grocery workers run their own health risks in working in such an exposed environment.
They disinfect keypads, freezer handles and checkout counters as hundreds of people weave around them, sometimes standing too close for comfort amid the pandemic.
Some work for hours behind clear plastic barriers installed at checkout counters, bulwarks against sudden sneezes or coughs that can propel germs.
They may not be doctors or nurses, but the importance of their work is finally getting recognition.
From South Africa to Italy to the US, grocery workers, many in low-wage jobs, have their work deemed essential to keep food and critical goods flowing.
Some fear falling sick or bringing the virus home to vulnerable loved ones, and frustration is mounting as some demand better workplace protections, including shorter hours to allow them to rest, and “hazard” pay for working closely with the public.
“Everyone is scared everywhere, here in South Africa and everywhere in the world,” said Zandile Mlotshwa, a cashier at Spar supermarket in the Johannesburg suburb of Norwood.
For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough, and the vast majority survive. But for others, especially older adults and people with existing health problems, it can be more severe, even causing pneumonia or death.
In the US, a handful of states, Minnesota and Vermont were the first, have given grocery workers a special classification that allows them to put their children in state-paid child care while they work.
Unions in Colorado, Alaska, Texas and many other states are pressing governors to elevate grocery workers to the status of emergency personnel.
“The government’s responsibility is to step up in these moments,” said Sarah Cherin, chief of staff for the United Food and Commercial Workers International Union in Seattle, the first US epicentre of Covid-19.
The union, which represents about 23,000 grocery workers and 18,000 health care workers, won early concessions for higher pay.
“We have always been a group of people who come to work when others stay home,” Ms Cherin said.
“Our workers need the same protection others get.”
US grocery and food delivery workers are insisting employers pay them more and provide masks, gloves, gowns and access to testing.
Whole Foods workers called for a recent “sickout” to demand better conditions, including double pay. A group of independent contractors for the Instacart grocery delivery service walked out to force more protections.
Jake Pinelli, who works at a ShopRite in Aberdeen, New Jersey, said customers do not stay six feet away from others and typically do not wear masks or gloves.
Staffers have protective gear, but the younger employees often give it to older co-workers or those they know have health conditions.
“Most of us are terrified,” Mr Pinelli said.
But he stays on because he wants to help.
“I have not only bills to pay, but it’s the only way right now I feel like I can do anything for my community and help out,” Mr Pinelli said.
Some have fallen sick.
The Shaw’s supermarket chain told workers last week at six stores in Massachusetts, New Hampshire and Vermont that one of its employees had been diagnosed with Covid-19.
The company reminded workers to wash their hands regularly and stay home if they don’t feel well.
At the Organic Food Depot in Norfolk, Virginia, cash is no longer used.
Customers cannot bring reusable bags.
Children under 16 are banned.
“If somebody fell sick in the store, the store is most likely going to shut down,” manager Jamie Gass said.
Mr Gass, 47, said his wife has asthma, which means she would be more vulnerable to the coronavirus.
Yet he feels pride going to a job that helps ensure people get fed in a crisis.
“Am I scared that I could catch this? Absolutely,” Mr Gass said.
“But I’m sure everybody is in that position.
“I’m just taking as many precautions as I can, so I don’t have to worry as much.”
In Italy, where more than 14,000 people have died of Covid-19, consumers seem to prefer smaller, family-run stores and markets.
One of them, the Innocenzi grocery store in Rome, was established in 1884 by Emanuela Innocenzi’s grandfather.
Its wooden shelves, marble entrance steps and cherished custom of clerks waiting on each customer hearken back to another era.
The small store now allows in only two customers at a time.
A dentist’s office provided masks, which employees wipe down with alcohol each day and reuse.
Ms Innocenzi shrugged off the pope’s praise.
“The doctors, the nurses have special training,” she said.
“This is our work.”
