ISSUE 33: Is there a direct linkage between livestock production and outbreaks of pfiesteria ?
RESPONSE: NO direct linkages have been scientifically documented between the production of livestock and outbreaks of the toxic dinoflagellate, pfiesteria. It is suspected that eutrophication of surface waters, or the enrichment of these waters with nutrients, contribute to these outbreaks. Scientists cannot link their presence or the emergence of toxic forms to any particular source of nutrients. There are many sources of nutrient inputs to surface waters. Livestock and poultry production are but two of these contributors. Solving the nutrient enrichment issue may or may not resolve our concerns with pfiesteria. According to a recently released U.S. Geological Survey report, nitrogen and phosphorus levels in the Neuse River have generally declined since 1980. Any linkage between animal production and pfiesteria outbreaks at this point is more speculation than scientific fact. The goal has been and should continue to be a long-term program for reduction of nutrients entering our water
