and quality A summary of his current projects are outlined below.
Working in Washington, D.C. Dr Parish spent ayear(199R-1999)
in Washington, D.C. as Policy Analyst in Food Safety for the
Congressional Research Ser ice (CRS). The CRS provides scientific
information to Congress to aid in the decision making process.
Parish produced reports, provided briefings and organized
seminars on food safety issues for Congressional members and
staff. The information was used to help make decisions on food
safety and other scientific issues that have far-reaching effects

Technologists (IFT). The IFT sponsored Parish's lello. ship to the
Congressional Science Fellowship Program, which is administered
by the American Association for the Advancement of Science

Lorrie Friedrich
Originally from: Pennsylvania
Education: B.S. and M.S. in microbiology from the University
of South Florida in Tampa.

Food Safety and Quality On The Forefront -

Dr. Parish's work, some of which is funded by the FDOC and USDA, focuses on food microbiology related to food safety
and quality. Here's a summary of some ongoing work:
* Investigations on the microflora, particularly human pathogens, found on the fruit surface at the processing plant. Dr.
Rente Goodrich is also a collaborator.
* Studies on Salmonella, Shigella and non-pathogenic E. coli on oranges and strawberries. This is a cooperative project
on microbiological food safety for fresh fruit involving UF-Gainesville and CREC, University of California-Davis and
Texas A & M. Dr. Goodrich is a collaborator on this project.
* Studies on Alicyclobacillus and possible disinfection methods. Alicyclobacillus is a spore-forming bacterium that can
cause spoilage of shelf-stable juices. Spoilage caused by Alicyclobacillus is characterized by a "horrific" odor.
* Investigations on whetherfhow bacterial pathogens can infiltrate citrus peel. This work, funded by the California Re-
search Board, will facilitate the development of food safety regulations by the Food and Drug Administration (FDA).
* Drs. Parish and Goodrich are involved in work related to Hazard Analysis Critical Control Point (HACCP) food safety
regulations for citrus juice. He and Dr. Goodrich serve on a Juice HACCP alliance and participate in HACCP training for
the citrus processing industry.
