Mask policies have challenged stores throughout the pandemic, and some of the biggest stores in America have updated rules

That designation includes more than two-thirds of US counties. The CDC changed its guidance in response to the rising spread of the new, highly transmissible Delta variant and low vaccination rates in many areas of the country.

Mask policies have challenged stores throughout the pandemic and led to disputes between opponents of masks and frontline workers trying to enforce safety measures. Most large chains had removed face covering requirements for vaccinated shoppers in May, following CDC guidance at the time easing mask-wearing for people vaccinated. Stores have continued to ask unvaccinated shoppers to wear masks.

Walmart is asking shoppers to wear masks inside stores in counties deemed at high risk, but not requiring it. Walmart will also post signs to remind customers about the CDC’s revised guidance and encourage them to wear masks.

Target

“We’ll follow all local mandates, as we have throughout the pandemic, and continue to monitor guidance from the CDC closely,” Target says.

Costco

Home Depot

Home Depot is requiring all workers to wear masks in all stores, regardless of vaccination status or the transmission risks of the area.

Kroger

Kroger “strongly encourages” all workers and customers to wear a mask in stores and facilities, but does not require them.

McDonald’s

McDonald’s told CNN on Tuesday that customers and staff inside restaurants in areas with high or substantial transmission will be required to wear a mask, regardless of vaccination status. The chain added the policy change reflects CDC guidance.

The fast-food giant also said masks have already been required for staff and customers who are not vaccinated.

Starbucks

Where mandated by local law or regulation, Starbucks will require customers wear masks in our stores.

Starbucks employees are also required to wear masks on their shift.
