Cornell researchers have created a method that uses geospatial algorithms, foodborne pathogen ecology and Geographic Information System (GIS) tools to predict hot spots where these pathogens may be present and spread on farms prior to harvest. Many of the recent outbreaks of foodborne pathogens have been linked to contamination on the farm.
The method, which can be applied to any farm, uses classification tree tools with remotely sensed data, such as topography, soil type, weather trends, proximity to various sources (water, forests) and more, to predict areas where pathogens are likely to be present.
The research was funded by USDA.
Baltimore based firm Sickweather has claimed that members of the public tweeting and posting to Facebook about their illness allowed them to declare that flu had hit the U.S. on October 18th.
Even though the Centers for Disease Control warned that the outbreak was getting off to its earliest start on December 3rd, that was still six weeks after Sickweather.

A severe flu strain has hit the US and is spreading to start the year 2013.
As of Dec. 29, 2012 the CDC categorized the illness as "widespread" in 41 states (see the map above and the list of states below), and 7 other states are seeing regional activity.
