MONTPELIER — Gov. Peter Shumlin says he wants to revive something like the Vermont Seal of Quality to signal to consumers they are getting a Vermont product that meets certain standards.

Shumlin joined Commerce Secretary Lawrence Miller and Agriculture Secretary Chuck Ross at a news conference Wednesday to say the state is working on a new marketing campaign.

Companies would have to meet certain criteria, which are still in development, indicating they have sufficient links to Vermont. The front-runner for the symbol that would be applied to the products is the moon-over-the-mountains logo widely seen on state websites.

Miller says the symbol likely will be accompanied by a special code that can be read by smart phones, which then would display where a product and its ingredients are made.
