Beef Patties Test Negative for E. Coli at CDA Lab

On Tuesday, October 22, the Colorado Department of Agriculture (CDA) laboratories received multiple lots of McDonald’s brand fresh and frozen beef patties collected from various Colorado McDonald’s locations associated with the ongoing E. Coli investigation. 

The CDA Microbiology Laboratory analyzed dozens of subsamples from all the lots and all samples were found to be negative for E. coli. CDA has completed all beef testing and does not anticipate receiving further samples.

If you’ve ever seen the movie “Wall-E,” you might remember the premise that green, growing life is precious and rare. Once it has been lost, the impacts on human life are devastating. Beyond the obvious fact that food provides life, if we lose the connection to how food is cultivated, it can be easy to forget that crops and livestock are themselves living, breathing entities. This means that they can be just as affected by diseases or bacteria as humans can.
