ROME, ITALY -- The customers wander around in the stores, touch the food and even lick their fingers while riffling through bills. Any one of them could have the virus, and pass it along.

Such are the nagging thoughts of grocery store workers in Italy and beyond: exhausted, underprotected and, many say, overly exposed to the coronavirus.

Around the world, while millions of people are quarantined at home, people can still shop for food at grocery stores, heightening risk for the sector's employees.

A 48-year-old supermarket cashier who tested positive for coronavirus died in March in Brescia in Italy's hard-hit north, raising questions about whether enough was being done to protect workers.

Unions say others employed in the sector may have died without their cases being reported as coronavirus cases. Last week, a 33-year-old supermarket security guard died of the virus in Italy.

Trapped behind checkout counters for hours at a time, or stocking shelves amidst customers on supermarket floor, workers say they are on the front lines -- and insufficiently protected.

"We're scared of bringing something back home with us," said Piera, a 31-year-old part-time cashier. She has worked for over a decade at a superstore in Novara, west of Milan, the city where the security guard died.

Workers who spoke to AFP asked that their last names not be used.

Shopping daily

The worries are not restricted to Italy.

"We can't compare cashiers and health workers, but let's say we're not quite yet all aware that we have to protect both of them," said Ana, a Spanish cashier in Alcorcon, outside Madrid.

Piera, in Italy's north, has been given disinfectant gel, gloves, and a mask, which she must wash herself for reuse. It was only last week that the store installed Plexiglass shields in front of each checkout counter.

Entire families show up to shop, many get too close to workers, and a few persist in licking their fingers before counting out their bills, said Chiara, a cashier at a superstore in Rome.

"They're buying stuff that I wouldn't be buying in an emergency," she added, listing "Sushi, Nutella, beer..."

Last month, a man was arrested in Genoa after spitting in the face of a supermarket cashier, local media reported.

Lack of precautions?

Unions in Italy have called for the government to require grocery stores to cut hours in order to relieve the burden on workers.

But Prime Minister Giuseppe Conte -- hoping to reduce panic and runs on supermarkets -- promised Italians on March 21 that stores will stay open.

The two hardest-hit regions of Lombardy and Piedmont, in the north of the country, recommended that markets take shoppers' temperatures before letting them in. But only some have done so, with others saying they cannot get hold of the thermal scanners they need.

In a open letter published on March 24, the secretary general of the Fisascat-Cisl union, which represents store cashiers and janitors, deplored the "almost total lack of any precautions" taken by the industry to protect its workers.

The main supermarket association in Italy, Federdistribuzione, has not issued specific coronavirus regulations to members, a spokesman told AFP. Instead, individual chains are taking measures.

That includes putting up signs instructing customers to maintain safe distances, equipping staff "as far as possible" with gloves and masks, and limiting the number of people who can enter stores, said the group.

Panicked shoppers

After the government locked down 11 towns in the north in late February to stem the initial spread of the virus, Piera witnessed panicked shoppers storming her store.

"It was so strange because we saw people panicking, freaking out," she said, calling it a "dystopian" experience.

Unlike doctors or police who might be trained in how to deal with high-stress situations, supermarket workers were caught unawares.

"We're just like anyone else, normal people, and so we didn't even have the psychological preparation to confront a situation like that," she said.

Workers struggle to control a constant fear of touching something, or someone, contaminated.

Ana in Spain said practically all the cashiers at her store were women, with children at home or parents to take care of.

"So you're at the checkout, but at the same time you're thinking of your mom, who is considered at risk, and you wonder if just in bringing her food, in touching the bags, you're going to transmit the virus to her," she said.

Stress has provoked meltdowns, and some workers have called in sick to avoid going to work.

Those who spoke to AFP said that in their stores staffing had shrunk by as much as a third, with some workers on sick leave or using vacation to care for homebound children.

Piera said she and others felt disregarded, and in need of "courage" to go to work every day. A Facebook page she set up in 2010, "Confessions of a Cashier", helps revive morale, with workers in the field sharing stores and commiserating.

"Some say we're heroes," Piera said. "I don't think so, we're just doing our jobs, even though we're overlooked."

"I don’t want to be a hero. Just respected, that's enough."
