Click the icon to the left of the MOFGA Certified logo to reveal the dropdown menu. From there you can see all production categories, or hide those you do not want to view (by unchecking the red checkbox). Beneath each scope title is a down arrow; click to see a list of all farms under that scope. Click the individual farm name to focus in on one producer.
