An Agreement on Pfiesteria Despite Disagreement

But Still Differ on Health Threat, Solution

Maryland and Virginia pledged yesterday to share medical data and resources in combating a fish-killing microbe, but they continued to differ on the organism's potential threat to humans and on how governments should respond.

Maryland Gov. Parris N. Glendening (D) hosted a six-state Governors' Summit in Annapolis that was called to address the problem. He basked in frequent praise for his aggressive response to the microbe, Pfiesteria piscicida.

At the same time, Glendening said his state will make a new effort to pass on medical data about the microbe's risks to humans that Virginia has been demanding, a pledge that Virginia Gov. George Allen (R) welcomed as an "important breakthrough." Glendening also tempered his earlier suggestions that the poultry industry might be a particular target for new restrictions on pollutants suspected of triggering the microbe's toxic form.

Meanwhile yesterday, Virginia officials said there was more evidence of pfiesteria in the Rappahannock River, where fish have been sickened and have lesions typical of those caused by the microbe. But the officials, backed by some independent researchers, reaffirmed Virginia's position that the organism poses no immediate health threat so long as it's not killing fish.

Also attending the summit were governors or senior officials of Delaware, West Virginia, Pennsylvania and North Carolina. In a day marked by broad smiles and pledges of cooperation, Glendening seemed eager to soften the distinctions drawn between his pfiesteria policy and Allen's.

"We realize that there are very different causes in different states, and different responses in different states," Glendening said.

Virginia has refrained from closing rivers, saying it will do so only if the microbe is suspected in significant fish kills. By contrast, Glendening has closed two Maryland waterways where fish have been sickened but not killed in large numbers.

At the summit's closing news conference, Glendening also said he will give poultry farms no more scrutiny than any other major source of nutrient runoff, which scientists blame for toxic blooms of pfiesteria.

"There is no time for finger-pointing," Glendening said. "There is no time for blaming one part of the economy or another. . . . The only place that I've seen any discussion of legislation being contemplated for poultry farmers or anything else was in the newspapers. I have not discussed that."

In response to a question at a Sept. 11 news conference, Glendening said he was considering new legislation to restrict chicken manure runoff. He said it was likely "we will have to go beyond the current status, which is voluntary compliance." Leaders of the poultry industry, Maryland's biggest agriculture sector, complained they were being unfairly targeted.

In hailing Maryland's promise to hand over medical information, Allen said he hopes Maryland soon will provide Virginia officials with data about a handful of Marylanders who apparently have suffered health problems from exposure to pfiesteria in its toxic form.

But Maryland officials warned that the data will be supplied only from those patients who waive their confidentiality rights. All patients have been promised that the raw data will be kept secret unless they give written consent to release the information, said Maryland Health and Mental Hygiene Secretary Martin P. Wasserman.

The medical information -- from which Maryland physicians concluded that several persons suffered memory loss and other problems after being exposed to pfiesteria -- is important because it was the basis for Glendening's decision to close streams if fish become sick but remain alive. Allen's medical advisers repeatedly have requested detailed information of the Maryland medical exams, so they can draw their own conclusions about pfiesteria's possible effects on human health.

Meanwhile in Richmond, officials reported that samples taken from the Rappahannock on Monday showed 600 cells per cubic centimeter of "pfiesteria-like" organisms in the water. North Carolina State University botanist JoAnn M. Burkholder -- who attended yesterday's summit and is considered the discoverer of pfiesteria -- characterized that as a high concentration.

But her analysis, requested by Virginia officials, has not yet confirmed that the organisms are indeed pfiesteria. And even if they are, they may not be toxic. Burkholder said waters with significant concentrations of pfiesteria in its nontoxic forms deserve monitoring but pose no immediate health threat.

Given the growing evidence of the presence of the microbe and the extent of its concentration in the river's waters, even state officials yesterday expressed surprise that there have not been widespread fish kills in the Rappahannock.

"Isn't that interesting that we are not having fish kills," Virginia Health Commissioner Randolph L. Gordon said.

Throughout the summit, Allen emphasized that evidence of pfiesteria's potential harm to humans is far from conclusive. "To date, we have not had a single person in Virginia report any ailment or sickness," Allen told reporters. "Maryland's approach is based on a different set of circumstances, really, from what we've had in Virginia."

Reminded that pfiesteria has become a minor campaign issue in Virginia's gubernatorial race, Allen, who is not running, said: "You know what the people of Virginia care about on this issue? They care about getting answers. They care about marine science. They care about medical science. They don't give a hoot about political science."

Also attending the summit were Delaware Gov. Thomas R. Carper (D), West Virginia Gov. Cecil H. Underwood (R) and representatives of the North Carolina and Pennsylvania governors.

There have been no confirmed outbreaks of toxic pfiesteria in Delaware, Pennsylvania or West Virginia, but all have rivers feeding the Chesapeake Bay.

Also addressing the group was U.S. Environmental Protection Agency Administrator Carol M. Browner. She pledged federal cooperation in understanding and combating pfiesteria's toxic forms.

The governors or their representatives signed an agreement pledging "to establish a mechanism for the effective exchange of information" on pfiesteria's biological traits; to notify each other immediately of suspected pfiesteria outbreaks; to work together for federal aid in the effort; and to "establish a regional technical team to report back by the end of this year . . . on the most effective measures" to evaluate pfiesteria's risks.

Glendening press secretary Judi Scioli said the D.C. government was invited to send a representative but did not respond.
