A. Morrie Craig – Endophyte Testing Laboratory, College of Veterinary Medicine, OSU (Corvallis)
Did you know that microbes have the capability to degrade many toxins? Dr. A. Morrie Craig is a professor in the
College of Veterinary Medicine whose research focuses on the degradation of plant toxins and environmental
pollutants by ruminal microbes. His research grew out of a finding that microbes in the sheep rumen allow sheep
to graze upon the toxic plant tansy ragwort without showing signs of liver toxicosis, while cattle cannot, as they do
not have an adequate amount of the ‘right’ microbes to degrade the toxins. Current research is being conducted
on understanding the fate and metabolism of endophyte fungal toxins found in forages in livestock. What happens
to these toxins once the animal ingests hay? Are they metabolized to a different chemical form? In what organ?
Are different species affected by these toxins at the same or different concentrations? Do any of these toxins
remain in tissues which humans consume? Dr. Craig also oversees the OSU Endophyte Service Laboratory which
uses HPLC (high-performance liquid chromatography) for quantifying the amount of specific endophyte alkaloids in
forages. Testing for ergovaline and lolitrem B in hay, straw, pellets, or grass from pastures is available for
veterinarians, animal owners, seed producers and straw exporters in order to provide ‘safe feed’ for livestock.
Other research focuses on nitroaromatic compounds which are widespread contaminants on over 16,000
Department of Defense (DoD) facilities, including manufacturing/handling sites and munitions ranges. An
estimated 700,000 cubic yards of soil and 10 billion gallons of groundwater require treatment at tremendous cost
to the DoD. Research in Dr. Craig’s lab investigates the bioremediation of munitions using a two-step process: 1)
explosives residues from contaminated soil are taken up into the blades of cool season grasses, partly remediated,
and then 2) made available for delivery to grazing sheep where degradation is completed by the microbes present
in their rumen. Molecular techniques including q-PCR, cloning and sequencing are utilized to determine which
species of bacteria are responsible for the degradation. LC-MS/MS (liquid chromatography-mass spectrometry)
analyses are used to monitor the degradation processes and develop degradation pathways.

David Farrer –Office of Environmental Public Health, Oregon Public Health (Portland)
Dr. Farrer works as a Public Health Toxicologist in the Oregon Public Health Division’s Office of Environmental
Public Health (OEPH). His primary work centers around assessing the human health risks associated with exposure
to chemical contaminants at hazardous waste sites and around other sources of point and non-point pollution
throughout Oregon. This work involves quantitative risk assessment, in-depth toxicological evaluations, public
health education, and risk communication. In this role, Dr. Farrer writes reports for the general public and attends
public meetings to explain findings in terms that are accessible to the lay public.
In addition to this site-specific work, Dr. Farrer responds to general questions about toxicology from other state
and federal agencies, legislators, and the general public. Dr. Farrer serves as a member of the Department of
Environmental Quality’s Air Toxics Science Advisory Committee which develops/selects health-based benchmark
air concentrations for air toxics in Oregon. As part of the OEPH’s Fish Advisory Group, Dr. Farrer reviews fish tissue
sampling data and help develop, update, and communicate fish consumption advisories for different waterbodies
throughout Oregon.

Steve Niskanen – NWFF Environmental (Philomath)
Mr. Niskanen is the Safety/Compliance Officer for NWFF Environmental, a company providing expert land-based
and marine spill emergency responses services, training, support and clean-up throughout the USA since 1991.
His responsibilities include tracking and scheduling training, checking and ordering (PPE), and staying up on rules
and regulations. With the many different situations NWFF encounters, proper PPE is essential. Training must be
kept current to ensure employees are competent to perform their duties. Among his duties is the opportunity to

business and have been in many unique situations. One of the trainers may be available for the students to
interview. This would be an eye opening opportunity. This job is very interesting due to the many situations that
arise, and varying locations our work takes us to. Each call is different and challenging in the hazards and locations
involved.
