Two children in Colorado were diagnosed with E. coli at Penrose St Francis Health Services in September of 20005. The young brothers had both eaten hamburgers at the USAF Academy faculty picnic.

Further investigation revealed that the hamburgers were purchased at a Wal-Mart store and were manufactured by the Flanders Provision Company.

Other cases of E. coli infection related to Flanders ground beef products has been recorded in other parts of Colorado. Flanders Provision Company recalled 900,000 pounds of their frozen ground beef patties in cooperation with the US Department of Agriculture. Several weeks later, an additional 184,000 pounds of Flanders ground beef patties were recalled.
