Bake Before You Bite: New E. coli Outbreak Report on Raw Flour

Cooking ingredients on a table before and after baking

A new CDC report describes an E. coli outbreak linked to raw flour in 2019. Several people in the outbreak said they ate, licked, or tasted raw dough or batter before they became sick. Read the report to find out more about the outbreak.

Raw flour is not a ready to eat food, meaning it hasn’t been treated to kill any germs in it. Germs are killed only when food made with flour is cooked. As tempting as it is, never eat raw dough or batter, even if it’s just a small taste.

For more information about how to stay healthy when handling raw dough or batter, please visit our updated CDC feature, also in Spanish.

New Antibiotic Resistance Data and Features on NARMS Now: Human Data

A suite of upgrades to NARMS Now: Human Data makes it even easier and faster to access CDC’s antibiotic resistance data for five enteric (intestinal) bacteria transmitted commonly through food: Campylobacter, E. coli O157, Salmonella, Shigella, and Vibrio (species other than V. cholerae). Data in this interactive, online database come from CDC’s National Antimicrobial Resistance Monitoring System (NARMS). The latest version of NARMS Now includes new search, report, and export features—and more data and categories for you to explore.

  • Narrow your search with new antibiotic pattern and antibiotic class-selection options or create your own custom antibiotic pattern searches.
  • Generate on-demand reports showing resistance by antibiotic, resistance by pattern, or minimum inhibitory concentration (MIC) distribution.
  • Export results to Excel, which provides both formatted tables and raw data.

Take a look at the data, observe trends, and enhance your analyses with the upgraded NARMS Now: Human Data. For more information on antibiotic resistance in foodborne and other enteric bacteria, visit CDC’s NARMS website.
