PORTLAND, Maine (AP) Maine is reconsidering its plan to allow bars to open for indoor service on July 1 because of recent COVID-19 outbreaks tied to bar patrons in other states.

Outbreaks involving dozens of customers and employees at bars in Jacksonville, Florida, and Boise, Idaho, show how easily the new coronavirus can spread, said Dr. Nirav Shah, director of the Maine Center for Disease Control. Tight quarters and loud talking or singing raise the risk of spreading the virus, he said.

“When we think about COVID-19, the duration and density of exposure, bars raise significant health concerns on both fronts,” Shah said. “This constellation of factors is prompting us in Maine as well as health authorities in a number of other states, including Massachusetts and Vermont, to re-evaluate our timeline for when bars can safely reopen.”

Bars, breweries and tasting rooms are currently allowed to open for outdoor seating only. Restaurants are allowed to open for indoor seating.
