Past CLF Fellow Voices Alarm on Non-Native Oyster Introduction

In an op-ed published in yesterday’s online edition of the Baltimore Sun, a Center for a Livable Future researcher urges federal and state officials to stay away from the introduction of non-native species in the Chesapeake Bay

Dr. Sharron Nappier, a former CLF Fellow whose research on the Bay’s oyster population was supported by CLF, says the introduction of non-native oysters into the bay may present greater public health consequences for consumers than native oysters. “The ecological benefits provided by the (non native) oyster’s filtration efficiency may have harmful repercussions for the health of consumers,” she warns.

The study conducted by Dr. Nappier while at the Bloomberg School of Public Health showed that non-native oysters were statistically more likely to harbor human viruses than native oysters. The oyster research was published in the November issue of the American Society of Microbiology’s peer-reviewed research journal Applied and Environmental Microbiology.
