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."
If people are still getting sick.
Seems it would take a while for the DNA to grow enough to supply fingerprints.
They will do an plugin for Google Earth?
It makes sense to spend our efforts trying to eradicate these strains in the domestic and wild animal populations. Otherwise, we run the risk of every farmer's field and every outdoor trail becoming a serious health hazard.
So while the epidemiologic effort to trace the source of the human outbreak is impressive, I think research into controlling it in animals is even more important.

A guy on tv said,"Who is shitting in the spinach!". The other guy said, "No one is shitting on the spinach, it is the fertilizer that is the source of the outbreak". To which the man replied, "O.K., Who's shitting in the fertilizer!". I laughed my ass off
The database is nice but it would be nicer if we'd simply apply what we already know to prevent the outbreaks in the first place. There's nothing new about composting and how to do it safely, yet we see big commercial farms rush the job and spray immature and dissease causing crap on food stuffs that will be eaten raw. I'm not sure if this is a problem of economies of scale or lax enforcement of existing laws. I am sure that the problem needs to be fixed in a way that won't discriminate against small operators who have never had the problem to begin with.
Friends don't help friends install M$ junk.
You have obviously not eaten at taco bell very often. Horrible diarrhea comes even without the food poisoning.
revolutionized the world of food safety
I think what he meant to say was, "the EXCITING world of food safety"
The spinach contamination a few months ago was traced to a field about 30 miles from where I live. The speculation is that some wild pigs (boars) were snacking on some spinach in the field and and an infected pig took a dump. It's probably not the first time this has happened, nor will it be the last. Shit happens.
I think a bigger problem is how so much clean spinach was destroyed as a result. The pig probably ruined a few heads of spinach. Those few heads got mixed in with a bunch of clean spinach as the spinach was pre-packaged. So that one pig's dump killed more people than would have died a few years ago if they had eaten head spinach. We could irradiate the packaged produce to clean the spinach further than its current 3 wash cycle but some people won't eat irradiated food. Even still, there's probably a variety of bug out there that would survive x-raying. If you eat spinach from a head of spinach, you run the risk of not cleaning it sufficiently as well as dealing with the multiple number of hands that have touched it between the field and your mouth. Never mind intentional contamination like the Tylenol killer came up with or the zealots in Oregon who contaminated a salad bar so voter turnout would be low.
In short, there's no way to guarantee that every piece of food that goes into your mouth is benign. With techniques such as the one described in the article, we'll hear of more people dying from contaminated food than we otherwise would have. People will panic, food will be destroyed, lawyers will sue and we'll plod along eating slightly more expensive food as a result. Will we be any better off? Probably not.
In fact, we may be worse off. As people demand more safety, government power will grow. We won't be safer, but the government will be larger which means we'll all be the poorer.
