Since it was launched Sept. 8, the social media festival Organic-Palooza has exposed millions of consumers to the industry and prompted many to participate online.

Brattleboro, Vt.-based Organic Trade Association, the event organizer, as well as dozens of other organic groups have shared information and encouraged feedback using the #OrganicFestival hashtag on Facebook, Twitter and Pinterest, according to a news release.

Social media uses hashtags to group similar subject postings so others can search by topic and see what’s trending.

Each day, the association will introduce a new discussion topic related to organic food and farming. Other association members will join in the online conversation.

More than 50 organic companies have committed to provide 60 prizes to consumers who share content during the event.

“We’re incredibly excited by the online buzz Organic-Palooza has generated just a few days into the campaign,” Laura Batcha, executive director and chief executive officer,” said in the release. “Brands are highly engaging and sharing on Twitter, while fans are jumping into the Facebook conversation. Our aim was to spark a grass fire of conversation about organic during the peak of Organic Harvest month in September, and so far it’s being wonderfully successful.”
