This week’s Open Mic guest is Kam Quarles, CEO of the National Potato Council. The potato industry is worth billions to the nation’s economy but is facing strong headwinds from regulatory issues, farm policy and global trade access. The group’s annual Potato Expo is expected to see record attendance this week in Austin, Texas including a presentation by USTR Chief Ag Negotiator Doug McKalip. Quarles says the industry is caught up in debate over the potato’s place in nutritional guidelines for adults and children.
