Dovel has released MyFoodAlerts.com.
The application uses public feeds from FDA, USDA, and CFIA and, using semantic technology, analyzes recall data. The application then translates the information into a user-friendly map interface accessible at myFoodAlerts.com. Data about the feed is also published into the data.gov format.
And, no, I do not know what the data.gov format is...

Water Canary analyzes water samples by using light and measuring what wavelengths to draw conclusions. A red light flashes to alert the user to a potential water problem.
The idea is not to use the device (currently built by hand and running about $200) to test water, but rather to collect data points for further investigation. The device was shown off at TED.
A study used GIS to explore the impact of avgas (a type of gas used in aircraft) on levels in the blood of children near airports in NC that use it. The FAA is looking at regulations on the gas.
Methods: We used Geographic Information Systems (GIS) to approximate areas surrounding airports in which lead from avgas may be present in elevated concentrations in air and may also be deposited to soil. We then used regression analysis to examine the relationship between residential proximity to airports and NC blood lead surveillance data in children aged 9 months to 7 years while controlling for factors including age of housing, socioeconomic characteristics, and seasonality.
The result suggest higher levels in the blood for children up to 1000M from the airport with the most pronounced effect within 500M.
