UNC Sea Grant re- searcher Mark Sobsey and his graduate stu- dents at the University of North Carolina at Chapel Hill are continu- ing to unfold the mys- teries of contaminated shellfish. Under Sobsey's direction, Anne Meinhold has taken a close look at the elimination of poliovirus in con- taminated oysters. She found that at lower water temperatures—between 43°F and 63°F—poliovirus is elimi- nated primarily through waste elimination and pseudo-feces. Pseudo- feces are particles the oyster draws in, but rejects as unsuitable to eat. As the thermometer rises, poliovirus, which is susceptible to higher temperatures, is made inactive by heat. Meinhold says that at the lower temperatures the poliovirus is elimi- nated slowly by the oysters, while at the higher temperatures the elimina- tion is much Please note that these images are extracted from scanned page images that may have been
