The 2010 Hawaii State Farm Fair, at Bishop Museum this weekend, will feature a celebrity cook-off and the Ag-Tastic Expo.

The cook-off will involve an Island Beef Stir-fry, starting at 12:15 p.m. Saturday. The beef comes courtesy of Michelle Galimba’s Kuahiwi Ranch in Kau, and all other food ingredients will come directly from the fair’s farmers market.

The expo will showcase samples of Hawaii-grown and locally made products from farm bureau members on Oahu, Maui, the Big Island and Kauai. They include Naked Cow Dairy; Hanalei Taro and Juice Co.; Maui’s Ono, producer of specialty dressings; honey producers from Molokai; Haliimaile Pineapple Co.; Lorie Obra, producer of award-winning Rusty’s Hawaiian coffee; and Will Tabios of Rising Sun coffee, another award winner.

The farm fair features a 4-H livestock exhibit with competition in lamb and beef categories, agriculture displays, the farmers market and exotic tropical plant displays and sales.

Admission is $7, $3 for children ages 4 to 12. The event runs from 9 a.m. to 8 p.m. Saturday and 9 a.m. to 5 p.m. Sunday. Purchase tickets at the door or beforehand at the museum box office or the Hawaii Farm Bureau office, 2343 Rose St. in Kalihi. Call 848-2074 or visit www.hfbf.org.
