No confirmed cases in Delaware so far, but Division of Public Health urges consumers to take precautions.

The Delaware Division of Public Health is advising Delawareans of a multistate outbreak of E. coli infections linked to chopped romaine lettuce from the Yuma, Arizona, growing region.

Before purchasing romaine lettuce at a grocery store or eating it at a restaurant, consumers should confirm with the store or restaurant that it is not chopped romaine lettuce from the Yuma region. Do not buy or eat it if the source of the romaine lettuce is unknown.

The lettuce could be contaminated with Shiga toxin-producing E. coli O157:H7 and could make people sick. To date, there have been no confirmed cases reported in Delaware, but DPH urges consumers to take precautions to prevent illness.

Consumers who have store-bought chopped romaine lettuce at home, including salads and salad mixes containing chopped romaine lettuce, should not eat it and instead throw it away, even if some of it was eaten and no one has gotten sick. If it is not known if the lettuce is romaine, do not eat it and throw it away.
