Three days ago, the Centers for Disease Control and Prevention (CDC) announced two E. coli O157:H7 outbreaks that have, so far, sickened a total of 44 people, killing one of them. Investigators are still working to confirm a food source, but some type of leafy greens, most likely romaine, are suspected in both. This is based on food histories of those sickened and genetic tests of the E. coli strains, each one closely resembling a strain linked to a previous romaine E. coli outbreak, or outbreaks. These aren’t the only outbreaks that are linked.

In fact, nine E. coli outbreaks since 2017 share either the same strain, the same romaine lettuce grower or both. That’s multiple links among nine outbreaks in the last three years.

Before we take a look at key events in the timeline of all nine outbreaks, some key facts.

Where Does E. coli O157: H7 Come From?

The E. coli serotype E. coli O157: H7 was discovered in 1982. It is among a small group of E. coli serotypes that produces a kind of poison called a Shiga toxin which, in humans, can cause a type of kidney failure called hemolytic uremic syndrome (HUS), other severe illnesses and death. E. coli O157: H7 live in the intestines of ruminant animals, cattle are the primary reservoir.

Arizona and California Grow Almost All the Lettuce in U.S.

Arizona and California grow 90 percent of the nation’s leafy greens, dividing the year between them. In November, production transitions to Arizona. In April, it shifts back to California. Each state has several growing regions, the areas linked to these outbreaks are Yuma, AZ and Salinas, CA.

E. coli Outbreaks Linked to Leafy Greens are Common

In the U.S., 40 E. coli outbreaks were linked to leafy greens between 2009 and 2018, according to the CDC. Together, those outbreaks resulted in 1,212 illnesses, 420 hospitalizations, 77 cases of HUS and eight deaths. Two of the nine interlinked outbreaks are ongoing, but so far these nine outbreaks have resulted in 541 illnesses, 241 hospitalizations, 50 cases of HUS and seven deaths in the U.S. Some of the outbreaks caused illnesses in Canada, too, which is why their government laid down a set of strict import rules on all romaine lettuce shipments originating from Salinas arriving in Canada from October 7, 2020 to December 31, 2020. These rules include required proof of origin and product testing. Our regulatory agency, the U.S. Food and Drug Administration (FDA), has made suggested modifications instead of required changes.

      • The Salinas-grown Romaine E. coli Outbreak, the Fresh Express Sunflower Crisp Chopped Salad E. coli outbreak, and an E. coli outbreak linked to Evergreens restaurants in Washington state are each linked to a different E. coli strain, but all of them have a common grower in Salinas.
      • FDA, CDC and state health officials end their investigation of the common grower associated with the romaine outbreak with cases in U.S. and Canada, the Evergreens outbreak in Washington state and the Fresh Express Sunflower Crisp Chopped Salad Kits outbreak with cases in the U.S. and Canada.

        Note: About half of the people who got sick needed to be hospitalized, 15 of them had HUS, a form of kidney failure associated with E. coli infections, including one of our clients, a teenage girl in Wisconsin who developed HUS.
      • Soil sample results have come back negative for the three outbreak strains of E. coli.
      • FDA states that although one grower was determined to be a common supplier for all three outbreaks based on available supply chain information, the romaine lettuce from this grower does not explain all of the illnesses seen in the three outbreaks.
      • The FDA reveals that (surprise!) when investigators arrived at the ranch in question there was no romaine in the ground and the fields had been plowed as “the growing season had already ended.”
      • Careful readers of this timeline will have noted the note in the 12/4/2019 entry stating that the growing season in Salinas ends in November and, therefore, the FDA’s approach to removing contaminated product from the market seemed unusual.
      • As a refresher: the FDA requested that the industry perform a voluntary withdrawal of romaine grown in Salinas from the market and requested that the industry withhold distribution of Salinas romaine for the remainder of the growing season in Salinas. This was the most efficient way to ensure that contaminated romaine was off the market.”
      • With the Salinas growing season over and no illnesses reported, the CDC says it is no longer advising people to avoid romaine lettuce grown in Salinas.

Multiple Links Among 9 Outbreaks in the Last 3 Years?

The FDA says there are a number of reasons why this keeps happening: Some of these growing areas are near land used for cattle grazing or feedlots. Runoff, from animal waste can contaminate water that produce growers use for irrigation;  leafy greens are perishable and their limited lifespan leaves a narrow product-testing window;  many of the outbreaks occurred as the growing season in one region was coming to a close and crops were no longer in the fields;  poor record-keeping by growers;  co-mingling of product by distributors and so on. But one thing that the FDA doesn’t mention is enforcement.

After each outbreak, the FDA releases a report of findings and proposes new voluntary measures the industry can take. “Unfortunately, proposed procedures and recommended actions do not protect consumers. Mandatory safety and tracking rules, effective testing and actual enforcement do,” said Food Safety Attorney Fred Pritzker. “These mandatory changes are long overdue.”
