YAPHANK - A new advertisement campaign called "Grown on Long Island" was launched today in Yaphank to encourage more people to buy farm-fresh and locally grown food.

A large farmer's market was held this afternoon at the Suffolk County Farm to celebrate local growers and launch the initiative, aimed at getting Long Island produce into more supermarkets.

"It's helping Long Island, it's keeping these farmers alive," says County Executive Steve Levy (R-Suffolk).

Frank Beyradt, the owner of Delea's Sod Farm, says events like this are essential to the survival of local farming.

Levy says his administration is also trying to get schools, hospitals and other county institutions that buy food in bulk to contract local farmers and help them boost their business.
