A Wegmans employee at the Perinton store has tested positive for COVID-19, prompting a Monroe County legislator to demand a full accounting from the grocery chain.

The Perinton employee last worked on March 22 at the store, which is located at 6600 Pittsford Palmyra Road, according to a statement from a Wegmans spokesperson.

The grocer said it is following guidance from the Monroe County Department of Health. The county did not immediately provide a comment to the Democrat and Chronicle on Monday evening.

County Legislator Rachel Barnhart, D-Rochester, who previously has pressed Wegmans to act on coronavirus issues, put out a statement Monday evening in which she said the company should make public how many employees have tested positive for coronavirus and in which store they worked.

"Employees and customers have a right to know if frontline workers in this crisis test positive for COVID-19," said Barnhart. "They deserve to make informed choices. In keeping this information secret, Wegmans damaged trust with its customers, workers and the community."

Grocery store workers are on the front lines of the nation's struggles against the coronavirus. They don't have the personal protective equipment or medical training provided to first responders and health care workers, but are exposed to large numbers of shoppers as demand and lines in grocery stores have surged. Supermarket employees are beginning to be infected across the country, including Wegmans stores around the state and Northeast.

A Trader Joe's worker in Westchester County, a Giant store employee in Maryland and two Walmart workers in Illinois have died due to COVID-19.

Wegmans has not made public any information in the Rochester area about employees contracting the coronavirus.

The store has been cleaned and sanitized multiple times since March 22 and the company said it extends its concern for workers and customers directly impacted.

"We continue to implement additional preventative measures for sanitation, hygiene, and social separation guided by the most up-to-date recommendations from health experts and continue to encourage all employees who think they may be sick to stay home – any employee with COVID like symptoms is eligible for a fully paid sick leave," said the statement from Wegmans.

It was unclear when the Perinton employee developed symptoms of COVID-19 and whether the employee worked any shifts while carrying the virus. Neither Wegmans nor the Monroe County Department of Health has publicly issued advice to co-workers or customers who might have come in contact with the employee.

A Wegmans employee at the Ithaca store has also tested positive for COVID-19, Tompkins County health officials reported Sunday.

That person worked multiple shifts at the store's coffee shop over the past two weeks. The Tompkins County Health Department urged customers who had close contact with any employee at the coffee shop from March 23 to April 4 to get tested for the virus and self-quarantine at home for 14 days from the last time they visited the kiosk.

Wegmans confirmed at the end of March an employee at a New England store contracted the virus.

Last week the supermarket chain said it doesn't plan on taking temperatures of employees.

"As standard practice, we encourage our employees to stay home and take care of themselves whenever they don’t feel well," the company said in a statement.

Barnhart wrote a letter to Wegmans on March 28 and then shared it on social media. In the letter, she said she had heard from Wegmans employees and their families who claimed they were not allowed to wear masks or gloves at work.

Wegmans agreed to change its policy five days later to allow workers to wear masks and gloves. The company said employees must watch a two-minute safety video on proper use and disposal of masks before wearing one.

Masks are not provided to employees.

Shortly after Wegmans relented and gave employees permission to wear masks, the federal government began advising everyone to wear cloth masks in public. County Executive Adam Bello echoed that sentiment at a news conference Monday.

The Washington Post reported Monday that a number of grocery workers have died in recent days.
