Abstract

Commercial Atlantic blue crabs (Callinectes sapidus) were exposed to 2.0x10(4) infectious waterborne oocysts of Cryptosporidium parvum. The study demonstrated that blue crabs can transfer C. parvum oocysts to persons involved in handling or preparing crabs and that they may contaminate other surfaces or products during storage.
