As part of a new order issued this week in Mendocino County, you’ll start seeing signs in businesses that serve food and beverages that show their vaccination policies. A green sign means employees are either vaccinated or test weekly and patrons must be vaccinated to dine inside. A yellow sign means employees are either vaccinated or test weekly but patrons do not need to be vaccinated to dine inside. A red sign means the business has no knowledge of whether employees are vaccinated or test, and patrons do not need to be vaccinated.
