For many businesses along the Gulf Coast, including those in North Central Florida, the oil spill could be devastating. The city of Cedar Key is not immune.

The owner of Southern Cross Sea Farms, a clamming business, says it could be shut down by the state if the oil reaches the coast. Between 100 and 200,000 clams are processed there daily and without his major source of income, the effects could be felt for sometime.

BP has already spent $350 million on clean up efforts. The total cost could run into the tens of billions.
