The Mexican Hass Avocado Importers Association pledged up to $25,000 for Hurricane Sandy relief through a Facebook promotion in December.

The Fallston, Md.-based group plans to donate $1, up to $25,000, for every Facebook engagement, including likes, shares and wall posts during the month of December to City Harvest, a relief organization providing food and support to communities affected by Hurricane Sandy, according to a news release.

The organization also chose a winner for its “Tis the Avocado Season” sweepstakes. Brad Golden of Ogallala, Neb., was chosen randomly among eligible entries for a trip to New York for a cooking lesson with chef Roberto Santibanez, chef and owner of Fonda restaurants and author of Tacos, Tortas and Tamales.
