In response to the coronavirus, two local grocery chains announced on Monday that store hours have been reduced.

Lunds & Byerlys’ store hours are now from 7 a.m. to 9 p.m. seven days a week until further notice. In addition, the Twin Cities grocery chain is asking that the hours between 7 to 8 a.m. each morning be reserved for those most at risk for COVID-19.

Reduced store hours are meant to cause less strain on staff and allow stores more time to replenish products and deep clean the stores. When stores reopen in the morning, the stores are asking shoppers to reserve the first hour for older adults and those with compromised immune systems.

“In doing so, our intent is to provide an opportunity for those individuals to be the first to shop after our overnight cleaning and stocking so they have increased access to essential products,” said a statement from Lunds & Byerlys.

Starting Tuesday, Kowalski’s Markets will have new, temporary store hours. “This is to ensure that in addition to our already intense cleaning practices, we can put even more cleaning, sanitizing, and restocking measures into place and continue to provide our customers and employees a safe and replenished environment to shop and work in,” according to a statement from the company.

Kowalski’s Markets Hennepin and Grand Avenue locations will be open from 6 a.m. to 10 p.m. and all other Kowalski’s Markets will be open from 6 a.m to 8 p.m. Opening times remain the same, but the closing hours are changed. Previously closing times varied by store between 10 p.m. to midnight. In addition, Kowalski’s Markets is asking shoppers to reserve the first two hours of when stores open for those at higher risk and those on the front lines.

“At this time, we are asking all customers to respect our request of having the 6 a.m. to 8 a.m. hours each day reserved for customers who are at higher risk for the virus, health care providers and first responders to shop,” the statement read. “Thank you for your patronage.”
