In the weeks since then, that total has grown to 84 individual cases reported, stretching across 19 states. Forty-two of those affected have been hospitalized, including nine who developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported to date.

As a result, the CDC has advised consumers to avoid whole heads and hearts of romaine, chopped romaine, and salads and salad mixes containing romaine lettuce, unless they can confirm the lettuce did not come from Yuma.
