FOOD SAFETY UPDATE: Outbreak of E. coli Infections Linked to Romaine Lettuce

November 20, 2018

The Centers for Disease Control and Prevention (CDC), public health and regulatory officials in several states, Canada, and the U.S. Food and Drug Administration (FDA) are investigating a multistate outbreak of Shiga toxin-producing Escherichia coli O157:H7 (E. coli O157:H7) infections linked to romaine lettuce.

CDC is advising that U.S. consumers not eat any romaine lettuce, and retailers and restaurants not serve or sell any, until we learn more about the outbreak. This investigation is ongoing and the advice will be updated as more information is available.

  • Consumers who have any type of romaine lettuce in their home should not eat it and should throw it away, even if some of it was eaten and no one has gotten sick.
    • This advice includes all types or uses of romaine lettuce, such as whole heads of romaine, hearts of romaine, and bags and boxes of precut lettuce and salad mixes that contain romaine, including baby romaine, spring mix, and Caesar salad.
    • If you do not know if the lettuce is romaine or whether a salad mix contains romaine, do not eat it and throw it away.
    • Wash and sanitize drawers or shelves in refrigerators where romaine was stored. Follow these five steps to clean your refrigerator.
  • Restaurants and retailers should not serve or sell any romaine lettuce, including salads and salad mixes containing romaine.

Read the CDC public notice for review along with an advisory from Health Canada.
