You'd think everyone could agree that something as grimly named as Pfiesteria would be toxic. It sure sounds toxic. But a researcher in North Carolina has been at the center of controversy for the last several years because of her claim that the organism does in fact harm fish and is responsible for periodic massive kills. A team at her own school, in fact, refuted her claims, saying when they repeated the experiments they were unable to observe the dinoflagellate microbe forming some of its previously reported toxic life-stages. The ball's back in Dr. JoAnn Burkholder's court today, with a new study that her team says refutes the findings published last summer stating that Pfiesteria is not toxic to fish or humans.About us
