Technology Vs. E.coli Outbreaks

jcatcw writes "The Centers for Disease Control and Prevention (CDC) found the patterns of illness in both of the recent E. coli outbreaks — packaged spinach and Taco Bell — using PulseNet, which uses a customized version of BioNumerics to conduct comparisons and analysis of samples in a SQL Server database. PulseNet holds the DNA fingerprints provided by pulsed field gel electrophoresis (PFGE). It operates at a national level and can link small, localized cases in a nationwide pattern. 'We can now see the connections you would not have seen before, which has revolutionized the world of food safety,' according to John Besser, clinical laboratory manager at the Minnesota Department of Health and a member of the Association of Public Health Laboratories."

Re:Not so revolutionary

[sporkme]

The point is that individual cases and the associated behaviors can be aligned and collated to trace the source of an outbreak. It is revolutionary in that many fewer people are getting sick.

There is no way to stop the spread of a disease directly with a database, but this system was fast and accurate enough to track down the source before the outbreak became something more like an epidemic. Taco Bell is so popular that this could have added up to hundreds of thousands of cases before someone realized the source.
