The state Division of Health reported 700 complaints from businesses not following Phase 2 restrictions.
The state has been stepping up enforcement efforts regarding social distancing, sanitation, and masks after receiving complaints.
Health Director Dr. Karyl Rattay said the complaints led to 220 visits.
Violations have included a lack of proper signage, staff not wearing facemasks, not controlling crowding, or incoming guests.
Rattay said the division has seen improvements in compliance, especially in the Dewey Beach area, but added that some businesses have resisted.
Rattay did not rule out fines and shutdowns if businesses do not comply.
Gaining praise from Rattay were Iron Hill Brewery, Bethany Blues and Harpoon Hanna’s.
“We know this is not easy,” she said of efforts to deal with guests and employees on compliance.
Restaurant owners have complained about employees getting abuse from guests who are upset with mask requirements.
Gov. John Carney earlier ordered bar areas of taprooms and restaurants to close in beach areas to avoid crowding issues.
