E. Coli O157:H7 in Lettuce Update as of May 1, 2018
The last update from the CDC on the E. Coli contamination of Romaine Lettuce was 5/2/18 and contained an update of cases and states.
To date, there are 121 cases of E Coli O157:H7 in 25 states. Of the 102 cases with known information, there have been 52 hospitalizations (51%), 14 cases (13.7%) of hemolytic uremic syndrome (HUS), and one (1) death in California. Reported illnesses started between March 13, 2018 and April 21, 2018. Since there is a 2-3-week lag time between infection of an individual to when the case is reported, these numbers may not include all cases that occurred after April 11.
Although 25 states have recorded cases, all the states except the following, have only 1-3 cases each. Those with more than 3 cases include Alaska (8), Arizona (8), California (24), Georgia (4), Idaho (11), Michigan (4), Montana (8), New Jersey (7), Pennsylvania (20), and Washington (6).

The good news is that the growing season of the Yuma region is typically done at the end of March, so cases of infection should decrease until completely gone. However, remember that there will be several weeks after the produce is picked before it isn’t in a refrigerator or on a shelf somewhere. The edible time period for Yuma-region romaine lettuce should be done/nearly done. Confirm where romaine lettuce is from until the CDC/FDA gives the all clear.
Previously Provided Info:
As reported in the last E Coli update on the FirstWatch website, the CDC widened their recommendations to NOT BUY OR EAT ANY ROMAINE LETTUCE UNLESS YOU CONFIRM THAT IT IS NOT FROM THE YUMA, ARIZONA GROWING REGION. This includes whole heads, hearts of romaine, chopped, baby, organic, and salads or mixes of greens that you can’t confirm don’t have Romaine lettuce, and any purchased at restaurants. Labels often do not indicate the area where the product was grown but will have labels of suppliers or distributors, so avoid the product unless you can confirm where it was grown.
It is worth noting that washing greens or other raw vegetables and fruits, even if using commercially prepared washes, baking soda, vinegar, or bleach is not reliable for killing E. Coli and other pathogens. Washing them with a cleansing agent (as above) with friction like a brush or cloth will remove pesticide residue, dirt, and other debris but pathogens (which are microscopic) can hide in crevices, cuts or blemishes on the vegetable/fruit, or even be covered with a film, produced by some bacteria, to assist in protecting the pathogen and resisting being washed or rubbed off.
