Multi-state Outbreak of E. coli O157:H7 (STEC O157)
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.
Update: Based on new information, CDC is narrowing its warning to consumers. Consumers should not eat and retailers should not serve or sell any romaine lettuce harvested from the Central Coastal growing regions of northern and central California.

DPHHS Press Release
There are no cases in Montana as of 12/7/2018. This site will be updated weekly, or as cases occur.
CDC Advice to Consumers
- Do not buy or eat any romaine lettuce that was harvested in the Central Coastal growing regions of northern and central California. If you do not know where the romaine is from, do not eat it.
- There is no recommendation to avoid romaine lettuce that is grown outside of this region; romaine from Yuma, the California desert growing region near Imperial County and Riverside County, Florida, and Mexico, for example, does not appear to be related to the current outbreak.
- There is no evidence that hydroponically-grown and greenhouse-grown romaine is related to the current outbreak.
- Romaine lettuce products will soon be labeled with a harvest location by region, but it may take some time before these labels are available.
- If you do not know where your romaine lettuce was harvested, do not eat it and throw it away.
