2004 PFGE Pattern Submissions
38,682 PFGE patterns submitted to PulseNet databases in 2004, an increase of 37% over 2003 submissions Increases in the 4 major pathogens – E. coli 37%– Salmonella 25%– Listeria 41%– Shigella 17%
18,729 of 38,682 (48.4%) of submissions in 2004 were electronic submissions to the databases (This is a PART measure for CDC that OMB evaluates. We exceeded the goal for 2004)– 27% increase over electronic submissions in 2003

Why should we go international with PulseNet?
We live in a global communityFoods produced in one part of the world are consumed in another part of the world, 100’s to 1000’s of miles awayDiseases transmitted through foods should be addressed as a global problemNeed an effective global early warning systemGlobal networking and communication will allow us to utilize scarce public health resources effectivelyLeverage the network to respond to other emerging infectious diseases or acts of bioterrorism

This new peer-reviewed, international journal publishes original papers and short communications on research and diseases caused by foodborne pathogens. Topics include emerging pathogens; emergence of drug resistance; methods and technology for rapid and accurate detection; strategies to destroy or control foodborne pathogens in food production and processing; and development of novel strategies for the prevention and control of plant and animal diseases that impact food safety. The Journal will include timely reviews and special reports on topics such as agroterrorism and the safety of organically grown and genetically modified foods.
Special PulseNet Issue Planned for March 2006
