The World Wide Web Implementation of the Regulatory Fish Encyclopedia |
Image Example |
---|---|
The Seafood Products Research Center (SPRC), SEA-DO, SAN-DO, and CFSAN have
collaborated to create the Regulatory Fish
Encyclopedia (RFE) Website at http://www.cfsan.fda.gov/~frf/rfe0.html.
The RFE, as a government service, uses the Internet and the graphical World Wide Web to disperse
fish species information within and outside of FDA.
The RFE is built upon the concept of the highly expandable "RFE PAGE" information container. An RFE PAGE is dedicated to a combination of pictorial, textual, graphical and numerical data for the theme of that page. For instance, RFE PAGE 0, General Browser, shows the top page of the RFE and links to available fish species. |
RFE 0: General Browser |
The RFE Website pairs fish images with biochemical "fingerprint"
patterns for widespread use. This helps the public, private and
educational sectors, as "Internet Consumers" of the RFE.
American consumers potentially lose millions of dollars per
year due to seafood economic fraud through species substitution.
The use of the RFE will reduce these fraudulent practices and save
consumers money. By publishing on the World Wide Web, the RFE information
is available to a far wider internationl readership at a reduced cost to
the government.
In this frame, RFE PAGE 0, Species Specific Browser to Pacific cod, indicates links to the various information pages available for this species. |
RFE PAGE 0: Species Specific Browser |
RFE PAGE 1 contains high quality images (drum scanned from high
quality 4" x 5" photographic transparencies) of finfish in the round and
in market form. Several
market product forms are viewable. Internet Users from over 30 countries access the RFE Website monthly. Three hundred unique users a month from all over the world download over 7500 images on a monthly basis. Educational and Trade Journals have asked and been granted permission to download and publish hardcopy images. |

RFE PAGE 2 provides general information for the species including geographical distribution, nomenclature variation, associated health risks in HACCP Guidebook (under construction) and other miscellaneous market information. |
RFE PAGE 2: Nomenclature and General Information |
RFE PAGE 3 provides detailed taxonomic information for the species
of interest. As in the example, details are provided for head size and
proportion. Features that are species unique are provided to aid in
species identification.
Internally, the RFE is a quick way for FDA scientists and inspectors to compare species in the lab and the docks to authentic specimens by their physical appearance and biochemical fingerprints for inference and deduction in economic fraud investigations. This is particularly useful when only fillets are available in the lab for identification. |
RFE PAGE 3: Taxonomy |
A key feature of the RFE that distinguishes it from other fish references
is the inclusion of species biochemical pattern information in RFE PAGE 4. Currently included are the isoelectric focusing protein patterns for the pH range 3-10 for fresh, frozen, uncooked seafood based on AOAC 980.16, although a detailed data stamp on each gel image reflects the experimental conditions. (Under construction are methods to add DNA fingerprinting information.) |
RFE PAGE 4: PAGplate IEF |
RFE PAGE 5 contains numerical and graphical tools used to examine IEF protein fingerprint patterns. Potential substitutions are confirmed from protein patterns for
selected species using graphical and numerical tools for pattern matching
between specimen patterns.
Through the RFE project, FDA also maintains a National Fish Tissue Collection for the acquisition of
authentic species used in validation experiments in the lab. The RFE site
is hypertext cross-linked with
http://www.cfsan.fda.gov/~frf/seaintro.html
Worldwide users of the Internet may browse the top page of the RFE . Upon selecting the commercially relevant species of choice, users can proceed through a variety of information that is currently available for that species. There are now 94 species available with information that can assist in the identification of species substitution or assist in species education. |
