Oyster Bed Closures Threaten Growing Industry

A mystery of sorts threatens to stunt Massachusetts' small but growing oyster industry after illnesses linked to bacterial contamination forced the state to shut down beds for the first time ever.

Massachusetts has about 260 oyster growers who harvested roughly $12 million worth of oysters in 2012. That total is dwarfed by Louisiana, the highest-revenue oyster state, at $42 million, but it's in the top five nationally, according to federal statistics.
