Ready-to-bake cookie dough not ready-to-eat, study of E. coli outbreak finds

The investigation of a 2009 multistate outbreak of Shiga toxin-producing Escherichia coli (STEC), an important cause of bacterial gastrointestinal illness, led to a new culprit: ready-to-bake commercial prepackaged cookie dough. Published in Clinical Infectious Diseases and available online, a new report describing the outbreak offers recommendations for prevention, including a stronger message for consumers: Don't eat prepackaged cookie dough before it's baked.
