In 1999, I gave a talk to hundreds of farm leaders in Ottawa and told them that DNA fingerprinting – via PulseNet – would revolutionize foodborne illness outbreak investigations and that farmers better be prepared (the pic is from a 2003 awards ceremony where I was acknowledged for my outreach and extension efforts, the hair was fabulous).
Joanie Stiers of Farm Flavor writes that Michigan’s laboratory toolbox now includes whole-genome sequencing, allowing public health officials to stop the spread of foodborne illness faster than ever.
Since January of 2017, the Michigan Department of Agriculture and Rural Development (MDARD) has actively used whole-genome sequencing to precisely identify illness-causing pathogens and defend against widespread outbreaks of foodborne diseases.
MDARD’s Geagley Laboratory works in tandem with laboratories in the U.S. Food & Drug Administration’s GenomeTrakr network, which allows global collaboration in the fight against foodborne illness.
“With food now being distributed worldwide, illness can be spread from anywhere in the world,” says Ted Gatesy, laboratory manager of the microbiology section at Geagley Lab, which houses the whole-genome sequencing. “Using whole-genome sequencing, an illness can be tracked, for the most part, to the point in the food chain where it originated.
